For better control, the pulse signals are processed by the Position Command processing unit.
The structure is shown in the diagram below.

Position command processing unit
The upper path of the above diagram is the PR mode and the lower one is the PT mode that you
can select with P1.001. You can set E-Gear ratio in both modes to adjust the positioning
resolution. In addition, you can use either an S-curve or low-pass filter to smooth the command
(described below).
The Pulse Command Input Inhibit (INHP) function
In PT mode, when DI.INHP is on, the servo drive stops receiving external pulse commands and
the motor stops running. As this function is only supported by DI 8, setting 0x45 (DI.INHP) to
P2.017 (DI 8) is required.
