3.17 Parameters: 17-** Feedback

More parameters to configure the feedback from the
®
encoder (VLT Encoder Input MCB 102), resolver (VLT
Resolver Input MCB 103), or the frequency converter itself.
3.17.1 17-1* Inc. Enc. Interface
Parameters in this group configure the incremental
®
interface of the VLT Encoder Input MCB 102. Both the
incremental and absolute interfaces are active at the same
time.
NOTICE
Do not use incremental encoders with PM motors. In a
closed-loop control, consider absolute encoders or
resolvers.
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 datasheet.
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 N/A [10 - 10000 Enter the resolution of the
*
N/A] incremental track, that is the
number of pulses or periods per
revolution.
3.17.2 17-2* Abs. Enc. Interface
Parameters in this group configure the absolute interface
®
of the VLT Encoder Input MCB 102. 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.

SSI
Function:
[4. - Select the resolution of the absolute
131072. N/A] encoder, that is the number of counts
per revolution.
The value depends on setting in
parameter 17-20 Protocol Selection.
Function:
[1 - 16777216] Select the number of multi-turn revolutions.
Select value 1 for single-turn type encoders.
Function:
[13 - 25 Set the number of bits for the SSI
*
N/A] telegram. Select 13 bits for single-turn
encoders and 25 bits for multi-turn
encoders.
Function:
[100 - 0 kHz] Set the SSI clock rate. With long encoder
*
cables, the clock rate must be reduced.
Function:
Gray code
Binary code Set the data format of the SSI data.

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.
