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 cat-
alog 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.
Depending on the value of FB1.IDENTIFIED, FB1.ENCRES changes between read-only and read-write.
The following table lists the FB1.IDENTIFIED values and FB1.ENCRES's corresponding type.
