SPEED Header - J3

The SPEED header section (J3) is used for speed settings, number of dispense
settings, and switching between stall detect (sensor) and non-sensor mode. This is a
dual row 0.100” pin header. Functions are actuated by means of connecting pins using
industry standard shunts or by DIP Switch Assembly. This header contains the controls
for speed settings, stall detect enable, and number of dispenses. The pinout for this
connector is as follows:

1.

Speed - 10 rpm

2.

Speed - 20 rpm

3.

Speed - 40 rpm

4.

Speed - 80 rpm

5.

Speed - 160 rpm

6.

Speed - 320 rpm

7.

Speed - 640 rpm

8.

Sensor detect on/off - The default (no shunt) is sensor enabled ( See page 1

item#4).
9.

Dispense - 1 dispense

10.

Dispense - 2 dispenses

11.

Dispense - 4 dispenses

12.

CW/CCW - The default (No Shunt) CW Rotation

13. Not

Used.


These pins are set up as a binary system. This means that multiple pins shunted will
add their values together. For example, to set the motor to run at 500 rpm you must
shunt pin pairs Switches 6, 5, and 2 (320+160+20=500 rpm). The shunts can give a
maximum speed of 1270 rpm and 7 dispenses. (see page H1 item # 4) The controller
will run at constant speed until one of the dispense setting pairs are shunted.

The motor will then home itself to the proper starting point and begin the desired
number of dispenses upon connection of the Start Pulse Signal and the Start Pulse
Common pins (Header J2, pins 3 and 4) by means of a momentary switch.
