RESOLVER
SETUP::MOTOR CONTROL::RESOLVER
Designed for PMAC Control Mode.
This block defines the parameters used to set up the resolver.
Parameter Descriptions
NAME
PREF: 133.01
Default: PARVEX
Range:
Set the resolver’s name.
POLES
PREF: 133.02
Default: 2
Range: 2 to 20
Set the resolver’s number of poles
. For a standard resolver, this number is 2.
When using a
n ENDAT encoder with a belt-pulley system on the feedback (typically PARVEX Torque motors), this parameter
can be
used to declare the ratio between the motor shaft and the encoder. The parameter named PULLEYBELT RATIO in this
block
can also be used to enter this ratio. Use either POLES or PULLEYBELT RATIO parameter.
For example :

When using a
resolver with a pulley belt, it is better to use the PULLEYBELT RATIO parameter in this block to enter the ratio.
