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
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 an 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 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:
Tratio =
VOut
VIn
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].

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

3.18.4 17-6* Monitoring and App.
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:
Function:
[0]
*
Clockwise
[1]
Counterclockwise
17-61 Feedback Signal Monitoring
Select which reaction the adjustable frequency drive should take if
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.
