• Use MFAI to individually set the four torque limit quadrants. Set H3-02, H3-10 = 9, B, C [MFAI Function
Select = FW Trq Lim, Rev Trq Lim, RegenTrqLim].
• Use MFAI to set all four torque limit quadrants together. Set H3-02, H3-10 = D [GenerTrqLim].
• Use a communication option to set all four torque limit quadrants together.
This figure shows the configuration method for each quadrant.
Figure 12.127 Torque Limits and Analog Input Setting Parameters
Note:
• When L7-01 to L7-04 and analog inputs or communication option torque limits set torque limits for the same quadrant, the drive
enables the lowest value.
In this example of parameter settings, the torque limit for quadrant 1 is 130% and the torque limit for quadrants 2, 3, and 4 is 150%.
Settings: L7-01 = 130%, L7-02 to L7-04 = 200%, and MFAI torque limit = 150%
• The drive output current limits maximum output torque. The torque limit is 150% of the rated output current for HD and to 120% of
the rated output current for ND. The actual output torque is not more than the limits of the drive rated output current when you set the
torque limit to a high value.

◆ n3: HIGHSLIP/OVEREXCITATION BRAKE
n3 parameters configure High Slip Braking and Overexcitation Deceleration.
■ High Slip Braking (HSB)
High slip braking quickly decelerates motors without braking resistors.
This lets you stop a motor more quickly than with the ramp to stop processes. This function is best for
applications that do not frequently stop the motor, for example the fast stop function for high-inertia loads.
Braking starts when the MFDI for HiSlipBraking [H1-xx = 32] activates.
Figure 12.129 High Slip Braking Time Chart
An induction motor is necessary to use high slip braking. Set A1-02 = 0 [Control Method = V/f Control] to enable
high slip braking:
Principles of Operation
HSB increases motor slip by significantly decreasing the frequency supplied to the motor at the same time that
deceleration starts. A large quantity of current flows through the motor to increase the motor loss, and the motor
decelerates while the motor windings consume the regenerative energy.
The drive keeps the motor current at a constant level during deceleration to prevent overvoltage and do automatic
braking and it also keeps a slip level that causes the maximum quantity of deceleration torque.
High Slip Braking Precautions
• Do not use the high slip braking function in these applications:
- Frequent deceleration
- Deceleration time differences
- Continuous regenerative loads
- It is necessary to accelerate again during deceleration
• Motor loss increases during high slip braking. Use this function when the duty time factor is 5% ED or less and
the braking time is 90 seconds or less. The load inertia and motor characteristics have an effect on the braking
time.
678
12.9 n: SPECIAL
• The drive ignores the configured deceleration time during high slip braking. To stop motors in the configured
deceleration time, set L3-04 = 1 [StallP@Decel Enable = Enabled] and L3-50 = 3 [StallP@Decel Mode =
HiFlux Overexcitation].
• You cannot use high slip braking to decelerate deceleration at user-defined speeds. To decelerate at user-defined
speeds, use the overexcitation deceleration function.
• You cannot accelerate the motor again during high slip braking until you fully stop the motor and input the Run
command again.
• You cannot use high slip braking and the KEB Ride-Thru function at the same time. If you enable those two
functions, the drive will detect oPE03 [Multi-Function Input Setting Err].
■ Overexcitation Deceleration
Overexcitation deceleration quickly decelerates motors without braking resistors. This lets you stop a motor more
quickly than with the ramp to stop processes.
Overexcitation deceleration increases excitation current during deceleration to cause a large quantity of braking
torque through motor overexcitation. You can set the deceleration speed to adjust the deceleration time for
overexcitation deceleration. Overexcitation deceleration lets you accelerate the motor again during deceleration.
Enter the Run command during overexcitation deceleration to cancel overexcitation deceleration and accelerate
the drive to the specified speed.
To enable this function, set L3-04 = 1 [StallP@Decel Enable = Enabled] and L3-50 = 3, 4 [StallP@Decel Mode
= HiFlux Overexcitation, HiFlux2 Overexcitation].
When L3-04 = 4, the motor will decelerate for the Deceleration Times [C1-02, C1-04, C1-06, or C1-08]. If the
drive detects ov [Overvoltage], increase the deceleration time.
When L3-04 = 5, the drive uses the value in C1-02, C1-04, C1-06, or C1-08 to decelerate and it adjusts the
deceleration rate to keep the DC bus voltage at the level set in L3-17 [DCBus Regul.Level]. The load inertia and
motor characteristics have an effect on the braking time.
Notes on Overexcitation Deceleration
• Do not use Overexcitation Deceleration with a braking resistor.
• Do not use Overexcitation Deceleration for these applications. Connect a braking resistor to the drive as an
alternative to Overexcitation Deceleration.
- Frequent sudden decelerations
- Continuous regenerative loads
- Low inertia machines
- Machines that have no tolerance for torque ripples
• Motor loss increases during overexcitation deceleration. Use this function when the duty time factor is 5% ED
or less and the braking time is 90 seconds or less. The load inertia and motor characteristics have an effect on
the braking time.
• You can use overexcitation deceleration in OLV control, but this control method decreases the precision of
torque control and braking efficiency. Use V/f control for the best results.
• The drive disables these functions during braking with Overexcitation Deceleration 2:
- Hunting Prevention Function (V/f Control)
- Torque Limit Speed Control (OLV Control)

deceleration to calculate the overexcitation level.

The best value of this parameter changes when the flux saturation characteristics of the motor change.
• Gradually increase the value of n3-13 to 1.25 or 1.30 to increase the braking power of Overexcitation
Deceleration. If the gain is too much, the motor can have flux saturation and cause a large quantity of current to
flow. This can increase the deceleration time.

WARNING! Sudden Movement Hazard. Make sure that the polarity is correct before you send a Run command. If the drive
incorrectly detects the polarity, the drive can rotate in the direction opposite of the Run command and cause serious injury or
death.
When you use a Yaskawa motor, check the motor nameplate for an “Si” value and set this parameter ≥ "Si × 2".
Consult the motor manufacturer for information about maximum setting values.
Find the Polarity of Magnetic Poles
When you start operation, the drive estimates the magnetic poles and finds the polarity of the magnetic poles.
Use U6-57 [n8-84: PoleDis IdDifVal] to make sure that the magnetic pole estimate was correct.
When you do High Frequency Injection Auto-Tuning, the drive automatically sets n8-84.

(0507)
Sets the function to keep the settings of changed parameters as user parameter defaults to use
(0 - 2)
during initialization.
When you set o2-03 = 1 [Set defaults], the drive saves changed parameter settings as user parameter setting
values in a part of the memory that is isolated from drive parameters.
When you set A1-03 = 1110 [Init Parameters = User / Solution Initialization] to initialize the drive, the drive
resets the internal parameter setting values to those user parameter setting values.
0 : No change
1 : Set defaults
Saves changed parameter setting values as user default settings.
Set o2-03 = 1 then push
to save the user parameter setting values. After the drive saves the setting value, o2-
03 automatically resets to 0.
2 : Clear all
Deletes all of the saved user parameter setting values.
Set o2-03 = 2 then push
to clear the user parameter setting values. The drive will automatically reset o2-03 to
0. If you delete the user parameter setting values, you cannot set A1-03 = 1110 to initialize parameters.
