Terminal function description
Common terminal for the contact input terminal (sink logic),
terminal FM.
Connect this terminal to the power supply common terminal
of a transistor output (open collector output) device, such as
a programmable controller, in the source logic to avoid
malfunction by undesirable current.
Common terminal for the 24 VDC power supply (terminal
PC).
Isolated from terminals 5 and SE.
Connect this terminal to the power supply common terminal
of a transistor output (open collector output) device, such as
a programmable controller, in the sink logic to avoid
malfunction by undesirable current.
Common terminal for safety stop input terminals
Common terminal for contact input terminal (source logic).
Common terminal for the frequency setting signal (terminal
2 or 4). Do not earth (ground).
Common terminal for terminals RUN and FU.
Common terminal for terminal SO.
