Ordering Information
7.3.6 VLT ®
The encoder module can be used as a feedback source for closed-loop flux control (parameter 1-02 Flux Motor Feedback
Source) and closed-loop speed control (parameter 7-00 Speed PID Feedback Source). Configure the encoder option in
parameter group 17-** Motor Feedback Option .
The Encoder Option MCB 102 is used for:
•
+
VVC
•
Flux vector speed control.
•
Flux vector torque control.
•
Permanent magnet motor.
Supported encoder types:
•
Incremental encoder: 5 V TTL type, RS422, maximum frequency: 410 kHz.
•
Incremental encoder: 1Vpp, sine-cosine.
•
7 7
HIPERFACE
•
EnDat encoder: Absolute and Sine-Cosine (Heidenheim) Supports version 2.1.
•
SSI encoder: Absolute.
NOTICE
The LEDs are only visible when removing the LCP. Reaction if there is an encoder error can be selected in
parameter 17-61 Feedback Signal Monitoring: [0] Disabled, [1] Warning, or [2] Trip.
When the encoder option kit is ordered separately, the kit includes:
•
®
VLT
•
Enlarged LCP fixture and enlarged terminal cover.
The encoder option does not support VLT
