/PSEL
Inputs speed reference. Input voltage range: ± 12 V max.
V-REF 1 (2)
T-REF 3 (4) Inputs torque reference. Input voltage range: ± 12 V max.
Function
Switches the speed control loop from PI (propor-
tional/integral) to P (proportional) control when
ON.
With internal set speed control selected: Switches
the servomotor rotation direction.
Switches control method between torque control
and speed control.
With speed control with zero-clamp function
selected: Reference speed is zero when ON.
With position control with reference pulse stop
selected: Stops reference pulse input when ON.
With overtravel prevention: Stops servomotor
when movable part travels beyond the allowable
range of motion.
Activates/deactivates external torque limit func-
tion.
With internal set speed control selected: Switches
the internal set speed settings.
