Multi-Function
Input 1, 2, 3 Defines Multi-Function Inputs.
(Factory setting: Multi-Step Frequency 1, 2, 3)
FX [M7]
Forward Run
Command
Forward Run When Closed and Stopped When Open.
RX [M8]
Reverse Run
Command
Reverse Run When Closed and Stopped When Open.
JOG [M6]
Jog Frequency
Reference Runs at Jog Frequency when the Jog Signal is ON. The Direction
is set by the FX (or RX) Signal. Jog Speed is set with I/O-30.
BX [M5] Inverter Disable
When the BX Signal is ON the output of the drive is turned off.
When the application uses an Electrical Brake to Stop, BX can
be used to turn off the output signal when the brake is applied.
RST [M4] Fault Reset Used for fault reset.
