This is a soft-starter for the PID setpoint.
RUN
The drive usually uses the acceleration and deceleration times set in C1: ACCEL / DECEL, but when PID control
is enabled, the drive applies C1-xx after PID output. If you frequently change the PID setpoint, the drive
responsiveness decreases. When resonance with PID control causes hunting, overshoot, or undershoot, set b5-17
for longer acceleration and deceleration times.
Decrease C1-xx until hunting stops, then use b5-17 to check the acceleration and deceleration. To enable and
disable the setting in b5-17 through an MFDI terminal, set PID SS Cancel [H1-xx = 75].

◆ b6: DWELL FUNCTION
The Dwell function momentarily holds the output frequency at start and stop.
This prevents motor speed loss when you start and stop heavy loads. The Dwell function is also enabled when
backlash on the machine side causes sudden movement at the start of acceleration and deceleration.
At the start of acceleration, the drive uses the output frequency and acceleration time set for the Dwell function to
automatically operate at low speed to minimize the effects of backlash. Then, the drive can accelerate again. The
Dwell function operates the same for deceleration.
For conveyor applications, the Dwell function also lets the drive interlock the output frequency and a delay time
for the holding brake on the load side.
The Dwell function momentarily stops during acceleration to prevent a PM motor from stepping out. Figure 12.34
shows how the Dwell function works.
Note:
When you use the Dwell function at stop, set b1-03 = 0 [Stopping Method Selection = Ramp->Stop].

■ Use Output Frequency Level to Switch Acceleration and Deceleration Times
The drive can use output frequency to automatically switch between different acceleration and deceleration times.
When the output frequency = C1-11 [Accel/Decel Time Switchover Freq], the drive automatically switches the
acceleration and deceleration times. Set C1-11 = 0.0 Hz to disable this function.
Note:
• Acceleration and deceleration times set to MFDIs are more important than the automatic switch using the frequency level set in C1-11.
For example, if you set the switchover frequency to C1-11, the drive will not automatically switch acceleration and deceleration times
when the MFDI terminal set for Ac/Dec Time1 [H1-xx = 18] is activated.
• If Motor 2 Select [H1-xx = 61] is activated, the drive will set the acceleration/deceleration time to C1-05 and C1-06 for motor 2 when
the output frequency is more than the frequency level set in C1-11.

Torque compensation is a function that increases voltage to increase output torque as compensation for
insufficient torque production at start-up or low-speed operation.
Voltage drops due to motor winding resistance cause torque generating voltage to decrease, which causes
insufficient torque. If the main circuit cable connecting the drive and motor is long, this can also cause insufficient
torque due to voltage drops.

■ Before You Adjust ASR Parameters
• Do Auto-Tuning and set up all motor data correctly.
• Always make adjustments with the load connected to the motor.
• Use analog output signals to monitor U1-16 [SFS Output Frequency] and U1-05 [Motor Speed] when you
adjust the ASR.
■ ASR Adjustment Procedure for AOLV/PM and EZOLV
Do this procedure to adjust ASR parameters:
1. Run the motor at zero speed or low speed and increase C5-01 [ASR PGain 1] until immediately before
vibration starts to occur.
2. Run the motor at zero speed or low speed and decrease C5-02 [ASR ITime 1] until immediately before
vibration starts to occur.
3. Check for oscillation when you run the motor at maximum speed.
4. If oscillation occurs, increase C5-02 and decrease C5-01.
When there is no oscillation, the adjustment procedure is complete.
5. Set the low-speed gain. Run the motor at zero speed or low speed and increase C5-03 [ASR PGain 2] until
immediately before vibration starts to occur.
Figure 12.45 Low-speed/High-speed Gain Settings
6. Set the low-speed integral time. Run the motor at zero speed or low speed and decrease C5-04 [ASR ITime 2]
until immediately before vibration starts to occur.
7. Set C5-07 [ASR Gain Switch Frequency].
8. Check for oscillation when you run the motor at speeds more than the setting in C5-07.
Note:
• If overshooting occurs when acceleration ends, decrease the value set in C5-01 and increase the value set in C5-02.
• If undershoot occurs at stop, decrease C5-03 and increase C5-04.
■ Use MFDI Switch for Proportional Gain
You can use the input terminals set for ASR Gain (C5-03) Select [H1-xx = 45] to switch the proportional gains set
with C5-01 and C5-03. When the configured input terminal is deactivated, the proportional gain set for C5-01 is
selected. When the terminal is activated, the proportional gain set for C5-03 is selected. The proportional gain
changes linearly over the time set in C5-02 [ASR ITime 1]. The signals from this MFDI are more important than
C5-07 [ASR Gain Switch Frequency].

■ Speed Waveform Monitoring Method
To make small adjustments of ASR parameters, monitor the speed waveforms when you make the adjustments.

The manufacturer recommends that you monitor the output frequency after SFS and the motor speed for delays in
response and differences in reference values.
■ Adjust ASR Parameters
Use Table 12.22 to adjust ASR. The table lists parameters for motor 1. You can make the same changes to motor 2
parameters when you run a second motor.
Note:
When adjusting the proportional gain and integral time, adjust the proportional gain first.

■ Multi-Step Speed Operation
The drive has a multi-step speed operation function that can set many frequency references in advance. Set
frequency references in d1-xx parameters. You can select the set frequency references with MFDI signals from an
external source. Activate and deactivate the digital input to select the frequency reference to change the motor
speed in steps. You can use the 16-step frequency reference and one Jog Frequency Reference (JOG command) to
switch the speed to the maximum 17-step speeds.
Note:
• The Jog Frequency Reference (JOG command) overrides all other frequency references.
• You can use the MFDI to switch the frequency reference when the motor is running. The drive will apply the enabled acceleration and
deceleration times.
• The default settings for Multi-Step Speed Reference 1 (master frequency reference) and Multi-Step Speed Reference 2 (auxiliary
frequency reference) are the analog frequency reference.
Also, voltage command input terminal AI1 and current input terminal AI2 for Multi-Step Speed Reference 1 (master frequency

input terminal.

Set the Jog Reference [H1-xx = 6] to one of the MFDI terminals DI1 to DI7.
Multi-step Speed Operation Combinations
Refer to Table 12.26 and Figure 12.49 for information about multi-step speed reference combinations. The
selected frequency reference changes when the combination of digital input signals from an external source
changes.

0.00 Hz
(0280)
Sets the frequency reference in the units from o1-03 [FrqDisplay Unit Selection].
(0.00 - 590.00 Hz)
RUN
Note:
• The upper limit value changes when the E1-04 [Max Output Frequency] and d2-01 [FRef Upper Limit] values change. Calculate the
upper limit value with this formula:
Upper limit value = (E1-04) × (d2-01) / 100
• When A1-02 = 6 [Control Method = PM AOLVector], the drive sets o1-03 = 1 [0.01% (100%=E1-04)].
• To set d1-01 to 1-step speed parameter in a multi-step speed operation, set b1-01 = 0 [Freq. Ref. Sel. 1 = Keypad].
