148 [Current Lmt Val]
Defines the current limit value when
[Current Lmt Sel] = “Cur Lim Val.”
Default:
Min/Max:
Units:

151 [PWM Frequency]
Sets the carrier frequency for the PWM
output. Drive derating may occur at
higher carrier frequencies. For derating
information, refer to the PowerFlex
Reference Manual.
Important: If parameter 053 [Motor Cntl
Sel] is set to “FVC Vector,” the drive will
run at 2 kHz when operating below 6 Hz.
