Control Input Details
Details on the input pins for the CN1 connector are described here.

High-speed Photocoupler Inputs:
Reverse Pulse/Forward Pulse Inputs, Feed Pulse/Direction Signal Inputs, or 90
°
Phase Difference Signal Input
Pin 3: +Reverse Pulse Input (+CW), +Feed Pulse Input (+PULS), or +Phase A Input (+FA)
Pin 4:
− Reverse Pulse Input ( − CW), − Feed Pulse Input ( − PULS), or − Phase A Input ( − FA)
Pin 5: +Forward Pulse Input (+CCW), +Direction Signal (+SIGN), or +Phase B Input (+FB)
Pin 6:
− 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.
• If the photocoupler LED is turned ON, each signal will go high as shown above.
