• Conguration:
P1322 [Direction Mode] = 1 “Bipolar”
P70 [Anlg in1 Sel] = Speed Ref A
P71 [Anlg In1 Cfg] = +/- 10
Note: DIP switch S9 should be
set to “On”
P133 [Digital In1 Sel] is kept at its default of “Stop/CF”.
P134 [Digital In2 Sel] = 5 “Run”

(1) Require for initial startup and
operational checks. Voltage must be
present at these points during operation. In
other words, these terminals must be made.
If open, the drive will be ‘Not Ready’.
(2) RUN – Edge sensitive signal that
initiates a Run command (0 1 = Run). If
the Drive is Run, voltage may be applied to
the armature causing the motor to reach the
desired speed.
