Select positive logic (active high) or negative logic (active low) for the phase
Z encoder. Positive logic phase Z (normally low) goes high at a signal; nega-
tive logic phase Z (normally high) goes low at a signal.
Select 1, 2, or 4 for the pulse multiplier depending on what type of phase-dif-
ference signals (Phases A and B) you require from the feedback pulses. Mul-
tiplier 1 sets the motor resolution equal to the encoder resolution. This means
an encoder with a resolution of 1,000 pulses/revolution connected to a motor
controls minimum motor rotation units in 1/1,000 revolution increments. With
Multiplier 1 for example, for feedback pulses in the CW direction the figure
below shows the generation of feedback pulses at the trailing edge of Phase
A when Phase B is high.
