Control Input Details
Details on the input pins for the CN1 connector are described here.
High-speed Photocoupler Input
Pin 3: +Reverse pulse (+CW), +feed pulse (+PULS), or +phase A (+FA)
Pin 4: −Reverse pulse (−CW), −feed pulse (−PULS), or −phase A (−FA)
Pin 5: +Forward pulse (+CCW), +direction signal (+SIGN), or +phase B (+FB)
Pin 6: −Forward pulse (−CCW), −direction signal (−SIGN), or −phase B (−FB)
Function
The functions of these signals depend on the settings of the Command Pulse Rotation Direction
Switching Selection (Pn006) and the Command Pulse Mode Selection (Pn007).
Note 1. If the Command Pulse Rotation Direction Switching Selection (Pn006) is set to 1, the rotation direction will be
reversed.
Note 2. If the photocoupler LED is turned ON, each signal will go high as shown above.
