The encoder module can be used as feedback source for
closed-loop flux control (1-02 Flux Motor Feedback Source)
as well as closed-loop speed control (7-00 Speed PID
Feedback Source). Configure encoder option in parameter
group 17-** Feedback Option.

Permanent magnet motor
Supported encoder types:
Incremental encoder: 5 V TTL type, RS-422, max. frequency:
410 kHz
Incremental encoder: 1 Vpp, sine-cosine

EnDat encoder: Absolute and Sine-Cosine (Heidenhain)
Supports version 2.1
SSI encoder: Absolute
NOTICE!
Incremental encoders are not recommended for use with
11 11
PM motors due to risk of wrong polarity.
NOTICE!
It is strongly recommended to always supply the
encoder through the MCB 102. It shall be avoided to use
external power supply for the encoder.
Encoder monitor:
The 4 encoder channels (A, B, Z and D) are monitored,
open and short circuit can be detected. There is a green
LED for each channel which lights up when the channel is
OK.
