7-12 Encoder Dividing Pulse Output Func-
tion
The Encoder Dividing Pulse Output Function outputs the position information obtained from the
encoder in the form of two-phase pulses (phase A and B) with a 90° phase difference. This function
also supports Z-phase outputs.
The following figure shows the waveforms of two-phase pulse outputs with 90° phase difference.
The maximum pulse output frequency is 4 Mpps.
The following figure shows the pulses that are output when the power is turned ON.
