Control circuit terminals Terminal arrangement

Example of control terminal wiring (Sink Logic)

Wiring sample of control logic terminal (source logic)

Note

*
This is in case frequency reference is given with voltage input. In case to use analog current input, configuration with switch on PCB is needed.
*
When to connect relay on intelligent output terminal, please install rectifier to absorb surge in parallel to that relay. Output circuit may be damaged with surge voltage when relay is turned on and off.

Switching logic of intelligent input terminal

Factory default of intelligent input terminal is sing logic. In order to switch to source logic, remove short bar on "P24" and "PLC" of control terminal and bridge between "PLC" and "L".
