Frequency division
output source
This parameter specifies the signal source of frequency division output.
Normal frequency division output
Input from quadrature pulses in phases A and B
First encoder (valid only for incremental encoders)
External grating ruler (or
encoder 2) phase-Z
signal type
The width for a phase-Z signal can be 1/4, 1/2, or 1/1. The starting phase of a signal in any width
corresponds to 4 types of electrical level in phases A and B. There are total 12 types in
combination. However, to ensure these combinations are applicable and the capture value is
normal in both forward and reverse directions, you need to set the phase-A–phase-B status values
in the high electrical level period of phase-Z signals. For the signals in 1/4 and 1/2 widths, only one
of phase-A–phase-B status values in the high electrical level period is required after the phase-Z
signal type is set. For the signals in 1/1 width, the phase-Z signal type must be the phase-A–
phase-B status value in the high electrical level period.
This parameter specifies the type of the second encoder.
