Parameter Descriptions
3.18.3 17-5* Resolver Interface
Par. group 17-5* 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 par. 1-01 Motor Control Princi-
ple set to Flux with motor feedback.
Resolver parameters cannot be adjusted while the motor is
running.
17-50 Poles
Range: Function:
2 [2 - 2 ] Set the number of poles on the resolver.
*
The value is stated in the data sheet for resolvers.
17-51 Input Voltage
Range: Function:
7.0 V [2.0 - 8.0 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:
10.0 kHz [2.0 - 15.0 Set the input frequency to the resolver.
*
kHz] 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
=
The value is stated in the data sheet for resolv-
ers.
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].
Option:
[0] Disabled

17-59 Resolver Interface
Activate the MCB 103 resolver option when the resolver parame-
ters are selected.
To avoid damage to resolvers par. 17-50 Poles – par. 17-53 Transfor-
mation Ratio must be adjusted before activating this parameter.
Option:
[0] Disabled
*
[1] Enabled
3.18.4 17-6* Monitoring and Application
This par. 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
Change the detected encoder rotation direction without changing
the wiring to the encoder.
This parameter cannot be adjusted while the motor is running.
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 par. 17-61 Feedback Signal Monitoring is an
electrical check of the hardware circuit in the encoder system.
Option:
[0] Disabled
