10.3 Encoder Option MCB 102
The encoder module can be used as feedback source for closed-loop flux control (par. 1-02
Flux Motor Feedback Source
) as well as closed-loop speed
control (par. 7-00
Speed PID Feedback Source
). Configure encoder option in parameter group 17-xx
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: 410 kHz
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
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.
NOTE!
The LEDs are only visible when removing the LCP. Reaction in case of an encoder error can be selected in par. 17-61
Feedback Signal
Monitoring
: None, Warning or Trip.
When the encoder option kit is ordered separately, it includes:
•
Encoder Option MCB 102
•
Enlarged LCP fixture and enlarged terminal cover
The encoder option does not support AutomationDrive FC 302 adjustable frequency drives manufactured before week 50/2004.
