Wiring instructions:

(1) Connect D1 and COM terminals of the frequency converter to the "forward run signal".

(2) Connect D2 and COM terminals of the frequency converter to the "reverse run signal".

(3) Connect the AI1 and GND terminals of the frequency converter to the "numerical control system analog signal".

(4) The T1B and T1C terminals of the frequency converter are connected to "change-to-signal".

(5) Connect the "fault output signal" to the T2A and T2C terminals of the frequency converter.
