Explanation of Terminals

Common terminal for H, O, O2, OI, AM, and AMI. Do not ground.

Power supply for frequency command input

Maximum frequency is attained at DC 10V in DC 0-10V range. Set the voltage at A014 to command maximum frequency below DC 10V.

O2 signal is added to the frequency command of O or OI in DC 0-±10V range. By changing configuration, frequency command can be input also at O2 terminal.

Maximum frequency is attained at DC 20mA in DC 4-20mA range. When the intelligent terminal configured as AT is on, OI signal is enabled.

Assign 5 functions to terminals.

(Refer to the standard specifications for the functions.)

Select sink or source logic with the short-circuit bar on the control terminals.

Sink logic: Short P24 to PLC / Source logic: Short CM1 to PLC. When applying external power source, remove the short-circuit bar and connect PLC terminal to the external device.

Assign 3 functions to two NO contacts and one NO-NC contact.
