Parameter Descriptions
3.18.3 17-5* Resolver Interface
This parameter group is used for setting parameters for
the MCB 103 Resolver Option.
Usually the resolver feedback is used as motor feedback
from Permanent Magnet motors with 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: Function:
2 [2 - 8 ] Set the number of poles on the resolver.
*
The value is stated in the data sheet 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 data sheet 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 data sheet for
resolvers.
17-53 Transformation Ratio
Range: Function:
0.5 [0.1 - 1.1 ] Set the transformation ratio for the resolver.
*
The transformation ration is:
V Out
T ratio =
V In
The value is stated in the data sheet 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). Needed when necessary to transfer the speed or
position information from one drive to another. To disable the
function, select [0] Disabled.
Option:
[0] Disabled

17-59 Resolver Interface
Activate the MCB 103 resolver option when the resolver
parameters are selected.
To avoid damage to resolvers 17-50 Poles – 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 MCB 102 Encoder option or MCB 103 Resolver
option 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
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 17-61 Feedback Signal Monitoring is an
electrical check of the hardware circuit in the encoder system.
