9.4 Encoder Option MCB 102
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.
Used for
•
VVC
plus
closed loop
•
Flux Vector Speed control
•
Flux Vector Torque control
•
Permanent magnet motor
Supported encoder types:
Incremental encoder: 5 V TTL type, RS422, max. frequency:
410kHz
Incremental encoder: 1Vpp, sine-cosine
Hiperface® Encoder: Absolute and Sine-Cosine (Stegmann/
SICK)
EnDat encoder: Absolute and Sine-Cosine (Heidenhain)
Supports version 2.1
SSI encoder: Absolute
NOTE
Incremental encoders are not recommended for use with
PM motors due to risk of wrong polarity.
NOTE
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.
