This parameter specifies the resolution of the external grating ruler (or second encoder). If the
second encoder is connected, the output is the pulses needed for each encoder rotation.

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
