Parameter Descriptions

3.18 Parameters: 17-** Feedback

Additional parameters to configure the feedback from the
encoder (MCB 102), resolver (MCB 103) or the frequency
converter itself.
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.
Option:
[0] None
[1] RS422 (5V TTL)
*
[2] Sinusoidal 1Vpp
17-11 Resolution (PPR)
Range: Function:
1024 [10 - 10000] Enter the resolution of the incremental
*
track, i.e. the number of pulses or periods
per revolution.
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
Option: Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
[0] None Select [0] None if the feedback sensor is an
*
incremental encoder only.
[1] HIPERFACE Select [1] HIPERFACE if the encoder is absolute
only.

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 parameter 1-01 Motor
Control Principle set to Flux with motor feedback.
Resolver parameters cannot be adjusted while the motor is
running.

Function:
[ 4 - Select the resolution of the absolute
131072] encoder, i.e. the number of counts per
*
revolution.
The value depends on setting in
parameter 17-20 Protocol Selection.
Function:
[13 - 25] Set the number of bits for the SSI telegram.
Choose 13 bits for single-turn encoders and 25
bits for multi-turn encoders.
Function:
[ 100 - 260 Set the SSI clock rate. With long
*
kHz] encoder cables the clock rate must
be reduced.
Function:
Gray code
Binary code Set the data format of the SSI data. Choose
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
parameter 17-20 Protocol Selection is set to [1]
HIPERFACE.
