5.3 Options and Accessories
Danfoss offers a wide range of options and accessories for
the frequency converter.
5.3.1 Fieldbus Options
Select the fieldbus option when ordering the frequency
converter. All fieldbus options are included on the control
card. No separate A option is available.
To change the fieldbus option later, change out the
control card. The following control cards with different
fieldbus options are available. All control cards have 24 V
backup as standard.

5.3.2 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-**
The encoder option MCB 102 is 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 not visible when mounted in an FCD302
frequency converter. Reaction in case of an encoder error
can be selected in
17-61 Feedback Signal Monitoring
: None,
Warning or Trip.
