Slip constant 3545 0.0 0.0 20.0
Gain for slip compensation. This value is
calculated by the control software and
cannot be changed.
Dead time comp 3550 msec 16.0 0.0 50.0
Sets the dead time (or firing delay time) of
the IGBTs for software compensation.
Feed forward
constant
3560 0.0 0.0 1.0
Sets the gain for voltage feed forward.
This is used to improve the torque current
regulator response.
Carrier
frequency
3580 Hz 600.0 100.0 1500.0
IGBT switching frequency. The control
adjusts the entered value according to
available resolution.
Parameter ID Units Default Min Max Description
PLL prop gain 3010 70.0 0.0 200.0
Proportional gain of input phase locked
loop (PLL).
PLL integral
gain
3020 3840.0 0.0 12000.0 Integral gain of input PLL.
Input current
scaler
3030 1.0 0.0 2.0
Sets the scaling for input current
feedback.
CT Turns 3035 200 50 3000
Secondary side turns for input current CT
(with primary turns equal to 5).
Input voltage
scaler
3040 1.0 0.0 2.0
Sets the scaling for input line voltage
feedback.

Note: Many of the parameters in the Output Processing section are automatically set up during auto-
tuning. They are presented here so the user can do additional fine-tuning of the drive. Additional fine-
tuning is not generally required, but may be needed in special circumstances.
