12.4 d: REFERENCE

◆ d2: REFERENCE LIMITS

d2 parameters set the upper and lower frequency limits to control the motor speed. Apply these parameters to for

example, run the motor at low-speed due to mechanical strength concerns, or if the motor should not be run at low

speed because of lubrication issues with the gears and bearings.

The upper frequency limit is set in d2-01 [FRef Upper Limit] and the lower limit is set in d2-02 [FRef Lower

Limit].

(0293)

Sets the lower limit for the master frequency reference (the first frequency of the multi-step speed

reference) as a percentage. The maximum output frequency is 100%.

This parameter does not change the lower limit of Jog reference, frequency reference for multi-step speed

operation, or the auxiliary frequency reference.

The drive operates at the value set in d2-03 when the frequency reference decreases to less than the value set in

d2-03.

Note:

When lower limits are set to parameters d2-02 [FRef Lower Limit] and d2-03, the drive uses the larger value as the lower limit.

◆ d3: JUMP FREQUENCY

The Jump frequency is a function that sets the dead band to a specified frequency band. If a machine that operated

at constant speed is operated with variable speed, it can make resonance. To operate the machine without

resonance from the natural frequency of the machinery mechanical system, use a frequency band jump.

You can program the drive to have three different Jump frequencies. Set d3-01 to d3-03 [Jump Frequency 1 to

Jump Frequency 3] to the median value for the jumped frequency and set d3-04 [Jump Frequency Width] to the

Jump frequency width.

When you input a frequency reference that is the same as or near the Jump frequency width, the frequency

reference changes automatically.

514

12.4 d: REFERENCE

The drive accelerates or decelerates the motor smoothly until the frequency reference is not in the range of the

Jump frequency band. The drive will use the active accel/decel time to go through the specified dead band range.

If the frequency reference is not in the range of the Jump frequency band, switch to constant speed operation.

Figure 12.51 Jump Frequency

Note:

• When you set Jump Frequencies 1 to 3, make sure that the parameters do not overlap.

• When the drive is in the range of the Jump frequency, the frequency reference changes automatically. When Jump is executed, the

output frequency changes smoothly as specified by the values set in C1-01 [Accel Time 1] and C1-02 [Decel Time 1].

12.4 d: REFERENCE

◆ d4: FREQUENCY UP/DOWN

The d4 parameters set the Frequency Reference Hold function and Up/Down and Up/Down 2 commands.

WARNING! Sudden Movement Hazard. When you use the drive in a lifting application, you must also install external safety

circuitry. The drive does not have protection against accidental load drops in lifting applications. Install electrical and/or

mechanical safety circuit mechanisms that are isolated from the drive circuitry. If you do not use external safety circuitry, the

drive could drop the load and cause serious injury or death.

WARNING! Sudden Movement Hazard. When you use a mechanical holding brake with the drive in a lifting application, you

must close the brake if an input terminal triggers the Baseblock command to stop drive output. If you enter the baseblock

command, the motor will suddenly coast and the load will slip, which can cause serious injury or death.

• Frequency Reference Hold Function Command: This acceleration/deceleration ramp hold command uses an

MFDI to momentarily stop the acceleration/deceleration of the motor, and continues to operate the motor at the

output frequency at which the command reference was input. Turn OFF the acceleration/deceleration ramp hold

command to continue acceleration/deceleration.

With a crane for example, use the function and a 2-stage push button to stop acceleration and operate at low

speed with one of the output frequencies.

• Up/Down command: The Up/Down command is a function to activate and deactivate an MFDI to increase and

decrease the frequency reference. The Up/Down command overrides frequency references from the analog input

terminal, pulse train input terminal, and keypad.

• Up/Down 2 command: The Up/Down 2 command is a function that adds a set bias value to the frequency

reference to accelerate or decelerate. The Up/Down 2 command activates and deactivates the MFDI to add a

bias value.

0 : Disabled

• Acceleration/Deceleration Ramp Hold

When you enter a Stop command or de-energize the drive, the hold value is reset to 0 Hz. The drive will use the

active frequency reference when it restarts.

• Up/Down Command

When you enter a Stop command or de-energize the drive, the frequency reference value is reset to 0 Hz. The

drive will start from 0 Hz when it restarts.

• Up/Down 2 Command

When you enter the Stop command or 5 s after you release the Up/Down 2 command, the drive does not save

the frequency bias. The Up/Down 2 function will start with a bias of 0% when the drive restarts.

1 : Enabled

• Acceleration/Deceleration Ramp Hold

When you clear the Run command or de-energize the drive, it will save the last hold value. The drive will use

the saved value as the frequency reference when it restarts.

Note:

When you energize the drive, continuously enable the MFDI terminal set for Ac/Dec Hold [H1-xx = 17]. If the digital input does not

activate, the drive will clear the hold value and set it to 0 Hz.

• Up/Down Command

When you clear the Run command or de-energize the drive, it will save the frequency reference value. The drive

will use the saved value as the frequency reference when it restarts.

• Up/Down 2 Command with Frequency Reference from Keypad

When a Run command is active and you release the Up/Down 2 command for longer than 5 s, the drive adds the

Up/Down 2 bias value to the frequency reference and sets it to 0. The drive saves the frequency reference value

to which the bias value was added. The drive will use the new value as the frequency reference when it restarts.

Figure 12.53 Up/Down 2 Example with Reference from Keypad and d4-01 = 1

• Up/Down 2 Command with Frequency Reference from Input Sources Other Than the Keypad

When a Run command is active and you release the Up/Down 2 command for longer than 5 s, the drive will

save the bias value in d4-06 [FRef Bias(Up/Dw2)]. The drive saves the frequency reference + d4-06 as a

frequency reference value. The drive will use the new value as the frequency reference when it restarts.

Figure 12.54 Up/Down 2 Example with Other Reference than Keypad and d4-01 = 1

Note:

To use the combination of the frequency reference hold function and the Up/Down 2 function, configure the Up/Down 2 upper limit

[d4-08] and lower limit [d4-09] correctly.

517

12.4 d: REFERENCE

Remove the Saved Frequency Reference Value

The procedure to remove the saved frequency reference value is different for different functions. Use these

methods to remove the value:

• Release the input programmed for Ac/Dec Hold [H1-xx = 17].

• Set an Up or Down command while no Run command is active.

• Use the Up/Down 2 Command to set d4-06 = 0.0 or set d4-06 = 0.0 during stop.

• Setting d4-03 = 0.00 Hz

When H1-xx = 65, 66 [d4-03: Up2 Command, d4-03: Dw2 Command] is active, the drive uses the accel/decel

times set in d4-04 [d4-03: Up/Dw2 Ramp Selection] to increase or decrease the bias value.

Figure 12.55 Up/Down 2 Bias when d4-03 = 0.00 Hz

• Setting d4-03 ≠ 0.00 Hz

When H1-xx = 65, 66 [d4-03: Up2 Command, d4-03: Dw2 Command] is active, the drive increases or

decreases the bias in steps for the value set in d4-03. The drive uses the acceleration and deceleration times set

The Up/Down 2 function setting changes the function of d4-06:

Note:

When the keypad sets the frequency reference, you do not usually use parameter d4-06.

• When d4-01 = 0 [FRef Hold Selection = Disabled] and a source other than the keypad sets the frequency

reference, the drive adds the value set in d4-06 to the frequency reference. If the value set in d4-06 is a negative

number, the drive will subtract it from frequency reference.

• When d4-01 = 1 [Enabled] and a source other than the keypad sets the frequency reference, the drive will store

the bias value adjusted with the Up/Down 2 command in d4-06 5 seconds after you release the Up/Down 2

command. The drive adds or subtracts the value set in d4-06 to the frequency reference.

Conditions that Reset or Disable d4-06

The drive resets and disables the bias value in these conditions:

• d4-01 = 0 and the Run command was cleared.

• H1-xx = 65, 66 [MFDI Function Select = Up2 Command, Dw2 Command] is not set.

• The frequency reference source was changed.

RUN

Handles frequency reference changes while H1-xx = 65, 66 [Up2 Command, Dw2 Command] is activated. When

the frequency reference changes for more than the level set in d4-07, the drive will hold the bias value, and the

drive will accelerate or decelerate to the frequency reference. When the drive is at the frequency reference, it

releases the bias hold and the bias follows the Up/Down 2 input commands.

This parameter is applicable only when an analog or pulse input sets the frequency reference.

◆ d6: FIELD WEAKENING / FORCING

d6 parameters set the field weakening and field forcing functions.

The field weakening function decreases the energy consumption of the motor. It decreases the output voltage of

the drive to a set level. The function decreases the motor excitation current inversely proportional to speed in a

constant output range, and does not let the induced voltage of the motor become more than the power supply

voltage. To enable this function, set Field weakening [H1-xx = 44] ON.

Note:

Use the Field Weakening function in constant light-load applications. To control the energy consumption of the motor for other load

conditions, use the parameters b8: ENERGY SAVING.

The Field Forcing function adjusts the delaying influence of the motor time constant when the drive changes the

excitation current reference and it also increases motor responsiveness. This function uses a high motor excitation

current reference for drive start-up only to help develop actual motor excitation current. Enable the Field Forcing

function to increase motor responsiveness.

Note:

You cannot use Field Forcing during DC Injection Braking.

Note:

Be aware of the following points when manually setting V/f patterns.

• To set linear V/f characteristics at frequencies lower than E1-06 [Base Frequency], set E1-07 = E1-09 [Mid A Frequency = Min Output

Frequency]. In this application, the drive ignores E1-08 [Mid A Voltage].

• Set the five frequencies as specified by these rules: Incorrect settings will cause oPE10 [V/f Data Setting Error].

E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04 [Min Output Frequency ≤ Mid A Frequency < Base Frequency ≤ Mid B Frequency ≤ Max

Output Frequency]

• Setting E1-11 = 0 [Mid B Frequency = 0 Hz] disables E1-12 [Min Output Voltage]. Ensure that the four frequencies are set according

to the following rules;

E1-09 ≤ E1-07 < E1-06 ≤ E1-04

• When you use A1-03 [Init Parameters] to initialize the drive, it will not reset E1-03.

■ Notes on Manually Setting V/f Patterns

Figure 12.61 Motor 2 V/f Pattern Diagram

• To configure a linear V/f pattern at frequencies lower than E3-06 [M2 Base Frequency], set E3-07 = E3-09 [M2

Mid A Frequency = M2 Min Out Frequency]. In this application, the drive ignores E1-08 [M2 Mid A Voltage].

E3-09 ≤ E3-07 < E3-06 ≤ E3-11 ≤ E3-04 [M2 Min Out Frequency ≤ M2 Mid A Frequency < M2 Base

Frequency ≤ M2 Mid B Frequency ≤ M2 Max Out Frequency]

Incorrect settings will trigger oPE10 [V/f Data Setting Error].

• If E3-11 = 0.0 Hz, the drive will ignore the V/f pattern settings.

• When you use A1-03 [Init Parameters] to initialize the drive, the drive will reset the manually set values for E3-

Sets the length of time that the drive must not receive a pulse signal to cause PGo [Encoder (PG)

(0.0 - 10.0 s)

Feedback Loss].

If the drive does not detect ouput pulses from the encoder for the time set in F1-14, it will trigger PGo.

Note:

• When A1-02 = 0 [Control Method = V/f Control], set H6-01 = 3 [PI Pulse Train Function = PG Feedback] to enable this parameter.

• Motor speed and load conditions can cause ov [Overvoltage] and oC [Overcurrent] faults.

◆ F6: COMMUNICATIONS, F7: ETHERNET

F6 and F7 parameters are used to set the basic communication settings and method of fault detection for the

communication option card. The communication option card parameters include common option card parameters

and communication protocol-specific parameters.

The following table lists the parameters that need to be set for each communication option card.

Refer to the technical manual for each communication option card for more information on installing, wiring, and

configuring the details needed before starting communication.

WARNING! Sudden Movement Hazard. Do test runs and examine the drive to make sure that the command references are

correct. If you set the command reference incorrectly, it can cause damage to the drive or serious injury or death.

■ Gateway Mode

Note:

When you use Gateway Mode, do not install the communication option in slave drives. If you install a communication option in a slave

drive, the drive commands and responses will not synchronize.

In gateway mode, you can use one communication option to communicate with more than one drive.

You can use one communication option to connect a maximum of five drives to the field bus communications.

Refer to Figure 12.63 for more information.

When you install a communication option on the master drive, you can use the RS-485 communication card to

transmit data to slave drives that do not have a communication option.

• Control commands: Run commands and frequency references

• Control responses: Output frequency and drive status (during run, faults)

• Read and write parameters

• Read monitors

Synchronous control

Not supported

Gateway Mode is not available with Yaskawa 1000-series drives or previous series drives.

Note:

• The communication speed in gateway mode is slower than the speed in fieldbus communications. Make sure that the speed is

acceptable for your system.

• Response speed with the communication option is slower than with point-to-point communications.

• Set H5-03 [Mbus Parity] to the same value on the master drive and slave drives.

WARNING! Injury to Personnel. Separately prepare safety protection equipment and systems, for example fast stop switches. If

the motor does not stop correctly from the disconnection of communications cable or electrical interference, it can cause serious

injury.

Restart the drive to apply the new settings.

Specify the number of slave drives you will connect.

Setting 0 will not let the drive respond to Modbus communications.

Set a slave address that is different from other slave devices.

Enter the same value that you use for the master drive.

To correctly detect the response timeout, do not change the value of H5-06 from the default value.

Set H5-09 ≥ 0.9. When H5-09 < 0.9, the drive will detect CE [Modbus Communication Error] before it detects a response timeout.

On each slave drive, set b1-01 [Freq. Ref. Sel. 1] and b1-02 [Run Comm. Sel 1] to 2 [Modbus].
