[6] 38400
3.17.3 17-5* Resolver Interface
3 3
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

N/A]
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.

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.

17-61 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.
