Description
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.
S-Curve Acc/Dec
S-curve is used to further soften the starting ramp.
The longer the S-curve time, the softer the starting
ramp.

Torque Comp
This parameter helps to produce better starting torque. It determines
the amount of torque or voltage boost based upon motor current and
motor resistance.
This parameter adjusts a filter on the output of the torque compensation
function. Increase to add torque stability, decrease to improve torque
response.
Carrier Freq
1: Normal Duty 1
2: Normal Duty 2
Carrier frequency sets the number of pulses per second of the output
voltage waveform.
0: Low Noise (Carrier frequency is randomly moduled for lower
audible noise)
1: Fc = 2.0 kHz
2: Fc = 5.0 kHz
3: Fc = 8.0 kHz
4: Fc = 10.0 kHz
5: Fc = 12.5 kHz
6: Fc = 15.0 kHz
F: Program (Determined by the settings of C6-03 thru C6-05)
Maximum carrier frequency allowed when C6-02 = F.
Minimum carrier frequency allowed when C6-02 = F.
Sets the relationship of output frequency to carrier frequency when C6-
02 = F.
