Explanation
(J4-1)
Accel/Decel profile and final run speed
command monitor point.
(J4-2, 14,

15)
for the external customer potentiometer
and step output interface and is referenced
directly to the internal drive module
GNDA.
(J4-3)
Connection to the wiper which is the

16, 17)
in conjunction with the external customer
potentiometer and step output interface
and is not referenced directly to the user
supply return.
(J4-18)
