Description
This parameter sets or gets the resolution of the motor encoder (encoder feedback systems only) in number of
counts per revolution for a rotary motor and the number of encoder pitches per motor pole pitch for a linear motor.
The number of encoder counts per revolution is obtained by multiplying the motor catalog resolution in units of
PPR by four. For example, for a 1024 PPR resolution motor, the number of encoder counts per revolution is
1024*4 = 4096. For this motor FB1.ENCRES must be set to 4096.
Forlinear motors,thevalueof FB1.ENCRESis settothenumberofencoderpitchespermotorpolepitch. Fora motor
