If the encoder has no inverted outputs, the encoder

cable can only have a length of max 3 meter. The

encoder input must then be terminated as shown.

The encoder surveillance circuit must be switched

off in parameter 350 [0].

If the encoder has no zero pulse, and the encoder

monitor is enabled (parameter 350), the inputs

77 and 78 must be terminated.

■ Electrical installation

Regarding programming of the digital and analog

inputs and outputs, see parameter group 300.

■ Bus connection RS 485

The serial bus connection is connected to terminals

68/69 of the frequency converter (signals P and N) in

accordance with the RS 485 (2-wire) norm. Signal

P is the positive potential (TX+,RX+), while signal

N is the negative potential (TX-,RX-).
