[Pulse/Enc Scale]
This parameter contains the scaling factor for both
pulse train inputs (TB2-7, 8) and encoder feedback
speed regulation (TB3 terminals 31-36).

Pulse Train Example:
4 Pole Motor, 60 Hz = Max. Speed.
The 1336–MOD–N1 option outputs 64 Hz/Hz.
At full analog reference, the pulse output will
be 60 Hz x 64 Hz/Hz = 3840 pulses/sec.
