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.

17-56 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 parameter 17-50 Poles parameter 17-53 Transformation
Ratio before enabling this parameter.

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:
[0] Clockwise
*
[1] Counter
clockwise
17-61 Feedback Signal Monitoring
Select which action the frequency converter should take if a
faulty encoder signal is detected. The encoder function in
parameter 17-61 Feedback Signal Monitoring is an electrical
check of the hardware circuit in the encoder system.
