Do not connect when a battery is connected to the host controller.
Speed reference speed input: ±2 to ±10 V/rated motor speed (Input gain can be
5 (6)
modified using a parameter.)
Torque reference input: ±1 to ±10 V/rated motor torque (Input gain can be modified
9 (10)
using a parameter.)

+12 V pull-up power is supplied when PULS, SIGN, and CLR reference signals are
13
open-collector outputs (+12 V power supply is built into the SERVOPACK).

Function
Switches the speed control loop from PI (proportional/
integral) to P (proportional) control when ON.
With the internally set speed selection: Switch the rotation
direction.

Torque speed
Speed control with zero-clamp function: Reference
speed is zero when ON.
Position control with reference pulse stop: Stops reference
pulse input when ON.
Overtravel prohibited: Stops servomotor when movable part
travels beyond the allowable range of motion.
External torque limit function enabled when ON.
With the internally set speed selection: Switches the
internal speed settings.
Input mode is set from the following pulses.
• Sign + pulse string
• CCW/CW pulse
• Two-phase pulse (90° phase differential)
