7.6.2 Pulse frequency division output mode setting
When using the encoder feedback output function, its important that users congure the sequence
of output phases ( A-leads-B or B-leads-A), the polarity of the Z index output and the frequency
division ratio (both numerator and denominator set individually). The frequency division ratio
impacts the pulses per revolution output by the drive.
Use parameter P3-12 to set the output pulse source, output pulse phase, and Z pulse output
polarity type. The functions corresponding to each bit are as follows.
