High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
The encoder input terminals (EAP/EAN/EBP/EBN/EZP/EZN) have a function that detects
disconnection when no encoder is connected.
When no encoder is connected, set both of the DIP switches SWENC1 and 2 to OFF to disable the
disconnection detection function.
When connecting an encoder without the phase Z signal, set the DIP switch SWENC2 to OFF to
disable the disconnection detection for the phase Z.
