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.

[Dwell Frequency]
This value sets the frequency that the drive will
immediately output (no Accel Ramp) upon a start
command. This parameter requires a programmed
