 Line-receiver Inputs:
Reverse Pulse/Forward Pulse Inputs, Feed Pulse/Direction Signal Inputs, or 90°
Phase Difference Signal Inputs
Pin 44: +Reverse Pulse Input (+CW), +Feed Pulse Input (+PULS), or +Phase A Input (+FA)
Pin 45: −Reverse Pulse Input (−CW), −Feed Pulse Input (−PULS), or −Phase A Input (−FA)
Pin 46: +Forward Pulse Input (+CCW), +Direction Signal (+SIGN), or +Phase B Input (+FB)
Pin 47: −Forward Pulse Input (−CCW), −Direction Signal (−SIGN), or −Phase B Input (−FB)
Functions
• The functions of these signals depend on the settings of the Command Pulse Rotation Direction
Switch (Pn41) and the Command Pulse Mode (Pn42).
• If the Command Pulse Rotation Direction Switch (Pn41) is set to 1, the rotation direction will be
reversed.
