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.
For linear motors, the value of FB1.ENCRES is set to the number of encoder pitches per motor
pole pitch. For a motor with 32 mm pole pitch, and a 40 µm encoder pitch, the value for FB1.-
ENCRES should be set to 32 mm/40 µm = 800.
