„ C5: Speed Control (ASR)
* The default will change when the control method is changed. These values are the defaults for the Flux Vector Control.
„ C6: Carrier Frequency
* 1. Fixed to 2:4 kHz for V/f.
For Open Loop Vector Control, can select from 2:4 kHz or 4:8 kHz (Fixed to 2: 4 kHz for 200 V class MxC for 45 kW and 400 V class MxCs for 22 kW and 45
kW).
* 2. Fixed to 2: 4 kHz for 400 V class MxCs for 110 kW and 160 kW.
