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

The parameter sets the number of pulses per rotation of the encoder pulse to be
[2500]
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.
0 - 1
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).
