Encoder Option Module (OPCENC)
The encoder module can be used as feedback source for closed loop Flux control (par. H-42) as well
as closed loop speed control (par. PI-00). Conf igure encoder option in parameter group EC-##.
Used for:
• Advanced Vector Control 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 Enocer: 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 (S, 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 keypad. In case of
an encoder error please see par. EC-61: None, Warning or Trip.
When the encoder option kit is ordered separately the kit includes:
•
