Fast Stop Time
Fast Stop Time Sets the time to decelerate from maximum frequency to zero for the
“Fast Stop” function. 0.0 ~

C1-11 020A
Accel / Decel Switch
Frequency
Acc/Dec SW Freq
Sets the frequency for automatic switching of accel / decel times.
Fout < C1-11: Accel / Decel Time 2
Fout > = C1-11: Accel / Decel Time 1
Multi-function input “Multi-Acc / Dec 1" has priority over C1-11.

Torque Compensation
Gain
Torq Comp Gain This parameter helps to produce better starting torque. It determines
the amount of torque or voltage boost based upon motor current and
motor resistance.

C4-02 0216
Torque Compensation
Primary Delay Time
Torq Comp Time This parameter adjusts a filter on the output of the torque compensation
function. Increase to add torque stability, decrease to improve torque
response.

S-curve is used to further soften the starting ramp.
The longer the S-curve time, the softer the starting
ramp.
