Group 91 ABSOL ENC CONF
Absolute encoder configuration; used when parameter 90.01 ENCODER 1 SEL /
90.02 ENCODER 2 SEL is set to (3) FEN-11 ABS .
The optional FEN-11 Absolute Encoder Interface module supports the following
absolute encoders:
• Incremental sin/cos encoders with or without zero pulse and with or without
• sin/cos commutation signals
• Endat 2.1/2.2 with incremental sin/cos signals (partially without sin/cos
incremental signals*)
• Hiperface encoders with incremental sin/cos signals
• SSI (Synchronous Serial Interface) with incremental sin/cos signals (partially
without sin/cos incremental signals*).
* EnDat and SSI encoders without incremental sin/cos signals are partially
supported only as encoder 1: Speed is not available and the time instant of the
position data (delay) depends on the encoder.

91 ABSOL ENC CONF
Firmware block:
ABSOL ENC CONF
(91)
This block configures the absolute
encoder connection.
91.01 SINE COSINE NR FW block: ABSOL ENC CONF (see above)
Defines the number of sine/cosine wave cycles within one revolution.
Note: This parameter does not need to be set when EnDat or SSI encoders are used in continuous
mode. See parameter 91.25 SSI MODE / 91.30 ENDAT MODE .
0…65535 Number of sine/cosine wave cycles within one revolution.
