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.
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.
This parameter cannot be adjusted while the motor is running.
Option:
[0]
[1]
*
[2]
17-11 Resolution (PPR)
Range:
1024 [10 - 10000 ] Enter the resolution of the incremental
*
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.
This parameter cannot be adjusted while the motor is running.
Option:
[0]
*
[1]
[2]

17-21 Resolution (Positions/Rev)
Select the resolution of the absolute encoder, i.e. the number of
counts per revolution.
This parameter cannot be adjusted while the motor is running. The
value depends on setting in 17-20 Protocol Selection.
Range:
Application

[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.
This parameter cannot be adjusted while the motor is running. The
parameter is only accessible when 17-20 Protocol Selection is set to
HIPERFACE [1].
Option:
[0] 600
[1] 1200

3.18.3 17-5* Resolver Interface
Parameter group 17-5* is used for setting parameters for the
MCB 103 Resolver Option.
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.
17-50 Poles
Range: Function:
2 [2 - 2 ] Set the number of poles on the resolver.
*
The value is stated in the data sheet for resolvers.
17-51 Input Voltage
Range:
7.0 V [2.0 - 8.0 V] Set the input voltage to the resolver. The
*
voltage is stated as RMS value.
