Parameter Setting
PrNo. Parameter Name Function/Content
The parameter sets the number of pulses per rotation of the encoder pulse to be
output to the host. Pulse should be set with dividing.
Directly set the number of pulses per rotation, in [Pulse/rev], necessary for a
device/system on your side.
Any value that exceeds the encoder pulse will be disabled.
A phase relation of output pulses from the rotary encoder is as follows: Phase B
pulse is behind Phase A pulse during rotation in CW direction (Phase B pulse is
ahead of Phase A pulse during rotation in CCW direction).

Phase Z is in sync with Phase A. You cannot reverse Phase Z.
Even by dividing, Phase Z outputs 1 pulse per rotation.
