3.17.3 17-5* Resolver Interface
This parameter group is used for setting parameters for the
®
VLT Resolver Input MCB 103.
Usually, the resolver feedback is used as motor feedback
from permanent magnet motors with parameter 1-01 Motor
Control Principle set to [3] Flux w/motor feedback.
Resolver parameters cannot be adjusted while the motor is
running.

Function:
Set the data format of the SSI data.
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.
Function:
[2 - 8 ] Set the pole number on the
resolver. The value is stated in the
datasheet for resolvers.
Function:
[2 - 8 V] Set the input voltage to the
resolver. The voltage is stated as
RMS value. The value is stated in
the datasheet for resolvers.
Function:
[2 - 15 kHz] Set the input frequency to the
resolver. The value is stated in the
datasheet for resolvers.

17-53 Transformation Ratio
Range:
0.5
*
17-56 Encoder Sim. Resolution
Set the resolution and activate the encoder emulation function
(generation of encoder signals from the measured position from
a resolver). Use this function to transfer the speed or position
information from 1 frequency converter to another. To disable
the function, select [0] Disabled.

17-59 Resolver Interface
Activate the VLT® Resolver Input MCB 103 when the resolver
parameters are selected. To avoid damage to resolvers, adjust
parameter 17-50 Poles parameter 17-53 Transformation Ratio
before enabling this parameter.
Option:

3.17.4 17-6* Monitoring and Application
This parameter group is for selecting extra functions when
®
VLT Encoder Input MCB 102 or VLT
103 is fitted into option slot B as speed feedback.
Monitoring and application parameters cannot be adjusted
while the motor is running.
17-60 Feedback Direction
Option:
