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.
17-50 Poles
Range:
Function:
2
*
[2 - 8 ] Set the pole number on the resolver. The value is
stated in the datasheet for resolvers.
17-51 Input Voltage
Range:
Function:
7 V
*
[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.
17-52 Input Frequency
Range:
Function:
10 kHz
*
[2 - 15 kHz] Set the input frequency to the resolver.
The value is stated in the datasheet for
resolvers.
17-53 Transformation Ratio
Range:
Function:

The value is stated in the datasheet for
resolvers.
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

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