Host Command Reference
PF - Position Fault
Compatibility: Servo drives and stepper drives with encoder feedback
Servo drives
Sets or requests the Position Fault limit in encoder counts. This value defines the limit threshold, in encoder
counts, reached between actual position and commanded position before the system produces a position fault
error.
Stepper drives:
Sets or requests the “percentage of torque” used in the Stall Prevention function for systems with an encoder
installed on the motor. Making this setting with the PF command requires that an SA (Save) command be sent
afterwards, then a power-down/power-up cycle before the change will take effect. It is recommended that the
Configurator software be used to make this setting.

with the Stall Prevention function turned on
PF PF=50
