2 : Enabled Only when Rotating REV
Note:
When
n3-23 = 1, 2
, the drive enables overexcitation only in the direction of motor rotation in which a regenerative load is applied. Increased
motor loss can decrease

faults.
◆
n5: Feed Forward Control
Feed forward control increases the responsiveness of acceleration and deceleration as specified by the speed
reference.
Increase the values set in
C5-01 and C5-03 [ASR Proportional Gain]
to apply feed forward control to machines that
have low rigidity and are possible to have hunting and vibration or to machines that have a large quantity of inertia.
Refer to
for more information about parameters related to feed forward control.
Set
A1-02 = 6 [Control Method Selection = Advanced Open Loop Vector Control for PM]
to enable feed forward
control.
Note:
•
You cannot use feed forward control to increase responsiveness in applications where you apply loads externally during run at constant
speed.
•
You cannot use feed forward control with motor 2.
Figure 2.128 Configure Feed Forward Control
■
Before You Use Feed Forward Control
Do one of these procedures before you use feed forward control.
•
Run Auto-Tuning to set motor parameters.
When you cannot do Auto-Tuning, manually set motor parameters with the information on the motor nameplate or
test reports. Set the
E2 parameters
for induction motors. Set the
E5 parameters
for PM motors.
•
Set
C5 parameters [Automatic Speed Regulator (ASR)]
individually to adjust the speed control loop (ASR).
•
If you can connect a motor to a machine and rotate it during Auto-Tuning, do Inertia Tuning.
The drive automatically adjusts feed forward parameters during Inertia Tuning.
•
If you cannot do Inertia Tuning, refer to
and set the parameters related to feed forward control
individually.
