4.6.2 Signal Descriptions
LOW Low Speed Input (J1-1)
SPEED When this input is activated (tied to GND) the Run Speed is set by
the Low Speed potentiometer.
DIR Direction Input (J1-2)
When this signal is high, motor rotation will be clockwise. Rotation
will be counterclockwise when this signal is low.
RUN Run Input (J1-3)
When this signal is low the motor will run in the direction set by
the DIR input at the desired set speed.
AWO All Windings Off Input (J1-4)
When this signal is low, AC and DC current to the motor will be
zero.
Caution: There will be no holding torque when the AWO
signal is low.
GND Signal ground (J1-5)
This ground point can be used for activating the discrete input
signals on pins J1-1 through J1-4 . It can also be used as a refer-
ence point for an external voltage input or in conjunction with the
+5V output (J1-7) to power an external speed potentiometer.
EXT External Run Speed Input (J1-6)
SPEED This is an optional input which can be used in place of the on
board Run Speed potentiometer. Input range can be either 0-5V
or 0-10V as defined by switch #8 described in Section 4.5.4.
+5V +5V output (J1-7)
This output is provided for powering an external speed potent i-
ometer. Pin J1-5 is used as the ground reference.
