17-11 Resolution (PPR)
Range:
Function:
1024
*
[10 - 10000]
Enter the resolution of the
incremental track, that is the
number of pulses or periods per
revolution.
4.16.2 17-5* Resolver Interface
This parameter group is used for setting parameters for the
VLT
®
Resolver Input MCB 103.
Resolver parameters cannot be adjusted while the motor is
running.
17-50 Poles
Range:
Function:
2
*
[2 - 8]
Set the pole number on the
resolver.
The value is stated in the datasheet
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 datasheet
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 datasheet
for resolvers.
17-53 Transformation Ratio
Range:
Function:

The value is stated in the datasheet
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). Use this function to transfer the speed or position
information from 1 frequency converter to another. To disable
the function, select

4.16.3 17-6* Monitoring and Application
This parameter group is for selecting extra functions when
VLT
®
Encoder Input MCB 102 or VLT
®
Resolver Input 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:
Function:
NOTICE
This parameter cannot be
adjusted while the motor is
running.
Change the detected encoder
rotation direction without changing
the wiring to the encoder.
