Parameter Descriptions
3.18 Parameters: 17-** Motor Feedb.
Option
Additional parameters to configure the Encoder (MCB 102)
or the Resolver (MCB 103) Feedback Option.
3 3
3.18.1 17-1* Inc. Enc. Interface
Parameters in this group configure the incremental
interface of the MCB 102 option. Note that both the
incremental and absolute interfaces are active at the same
time.
NOTICE
These parameters cannot be adjusted
while the motor is running.
17-10 Signal Type
Select the incremental type (A/B channel) of the encoder in use.
Find the information on the encoder data sheet.
Select [0] None if the feedback sensor is an absolute encoder
only.

3.18.2 17-2* Abs. Enc. Interface
Parameters in this group configure the absolute interface
of the MCB 102 option. Note that both the incremental
and absolute interfaces are active at the same time.

3.18.3 17-5* Resolver Interface
This parameter group is used for setting parameters for
the Resolver Option MCB 103.
Usually the resolver feedback is used as motor feedback
from Permanent Magnet motors with 1-01 Motor Control
Principle set to Flux with motor feedback.
Resolver parameters cannot be adjusted while the motor is
running.
MG33MH02 - Rev. 2013-09-30
Function:
[ 4 - Select the resolution of the absolute
131072 ] encoder, i.e. the number of counts
per revolution.
The value depends on setting in
17-20 Protocol Selection.
Function:
Set the number of bits for the SSI telegram.
Choose 13 bits for single-turn encoders and 25
bits for multi-turn encoder.
Function:
[ 100 - 260 Set the SSI clock rate. With long
kHz] encoder cables the clock rate must
be reduced.
Function:
between Gray or Binary format.
Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
Select the baud rate of the attached encoder.
The parameter is only accessible when
17-20 Protocol Selection is set to [1] HIPERFACE.
