Parameter Descriptions
3.18.3 17-5* Resolver Interface
This parameter group is used for setting parameters for
the Resolver Option MCB 103.
Usually the resolver feedback is used as motor feedback
3 3 from Permanent Magnet motors with parameter 1-01 Motor
Control Principle set to Flux with motor feedback.
Resolver parameters cannot be adjusted while the motor is
running.
17-50 Poles
Range:
2 [2 - 8 ] Set the number of poles on the resolver.
*
17-51 Input Voltage
Range:
7 V [2 - 8 V] Set the input voltage to the resolver. The
*
17-52 Input Frequency
Range:
10 kHz [2 - 15 kHz] Set the input frequency to the resolver.
*
17-53 Transformation Ratio
Range:
0.5 [0.1 - 1.1 ] Set the transformation ratio for the resolver.
*
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). Needed when necessary to transfer the speed or
position information from one frequency converter to another.
To disable the function, select [0] Disabled.

17-59 Resolver Interface
Activate the MCB 103 resolver option when the resolver
parameters are selected.
To avoid damage to resolvers parameter 17-50 Poles –
parameter 17-53 Transformation Ratio must be adjusted before
activating this parameter.

3.18.4 17-6* Monitoring and Application
This parameter group is for selecting additional functions
when Encoder option MCB 102 or Resolver Option MCB
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 reaction the frequency converter should take in
case 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.
