Parameter Descriptions
3.18 Parameters: 17-** Motor Feedb.
Option
Additional parameters to configure the Encoder (MCB 102)
3 3
or the Resolver (MCB 103) Feedback Option.

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.
NOTE!
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 None [0] if the feedback sensor is an absolute encoder
only.
Option:
[0]
[1]
*
[2]
17-11 Resolution (PPR)
Range:
1024
*

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.
17-20 Protocol Selection
Select HIPERFACE [1] if the encoder is absolute only.
Select None [0] if the feedback sensor is an incremental encoder
only.
Option:
[0]
*
[1]
[2]
[4]
NOTE!
This parameter cannot be adjusted while the motor is
running.

17-21 Resolution (Positions/Rev)
Select the resolution of the absolute encoder, i.e., the number of
counts per revolution.
The value depends on setting in 17-20 Protocol Selection.
Range:

This parameter cannot be adjusted while the motor is
running.
17-24 SSI Data Length
Range: Function:
13 [13 - 25 ] Set the number of bits for the SSI message.

[1] Binary code Set the data format of the SSI data. Choose
between Gray or Binary format.
17-34 HIPERFACE Baudrate
Select the baud rate of the attached encoder.
The parameter is only accessible when 17-20 Protocol Selection is
set to HIPERFACE [1].
Option:
[0] 600
[1] 1200
[2] 2400
[3] 4800
[4] 9600
