Resolver Poles 1793 Same as PNO 1790 2, 2 to 100 STOPPED
The number of poles in the resolver.
This is set to the resolver’s characteristic
A 2-pole resolver has one sine / cosine amplitude cycle for each mechanical rotation of the shaft.
Resolver Speed Hz 1822
Parameters::Option IO::Resolver
x.x Hz NEVER
The mechanical gearing of the resolver, reflecting resolver shaft turns per resolver coil turn.
This is set to the resolver’s characteristic.
For example, a multi-turn 2-pole resolver, that requires 10 resolver shaft rotations for each sine / cosine amplitude cycle, would use value 10.0.
Resolver Invert 1810 Same as PNO 1790 FALSE STOPPED
Used to set the direction of rotation which results in the position increasing positively, and the speed reporting as positive.
Resolver Position 1824 Same as PNO 1811 NEVER
(ENGINEER view level only.)
Actual resolver coil position, expressed as a count value, where one complete amplitude cycle is 65536 counts.
Resolver Turns 1811
Monitor::Inputs and Outputs
Parameters::Option IO::Resolver
NEVER
The integer number of completed resolver shaft mechanical turns.
Resolver Fraction Turns 1812 Same as PNO 1811 NEVER
The fractional part of the number of resolver shaft mechanical turns.
Resolver Speed Filter 1815 Same as PNO 1790 1000 10 to 10000 % ALWAYS
The corner frequency of the speed-tracking, single-order filter applied to the raw resolver speed, before it is reported in the Resolver Speed
parameters or used as speed feedback.
Expressed in terms of the ratio of filter corner frequency to raw resolver cycle frequency.
Used to remove speed ripple caused by the resolver measurement, particularly when the option is used as a reference speed input.
