Function:
[10 - 10000] Enter the resolution of the
incremental track, that is the
number of pulses or periods per
revolution.
Function:
[2 - 8] Set the pole number on the
resolver.
The value is stated in the datasheet
for resolvers.
Function:
[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.

17-56 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 [0] Disabled.
