Motor current and torque
CC, PI, PP commands
If using a stepper drive, PC sets or requests the continuous (RMS) current setting of the servo drive. If using a servo drive, PC
sets or requests the current setting (“peak of sine”) of the stepper drive, also known as the running current.
NOTE: This command is similar to CC. It differs only in that in addition to setting the continuous current of the drive,
PC also immediately saves the setting to NV memory. See CC command for further details.
