CN21 - Motor Output
Pin 1 - Motor output
Pin 2 - Motor output
Note:
Pins 1 and 2 may be swapped to reverse polarity (only necessary to match the forward and reverse
of the motor with those of the control).
Note: CN11 to CN13 & CN81 to CN84 are Molex KK, 0.1” [2.54mm]
series connectors, or equivalent spaced headers
CN11 - Tach Feed Back Connection
Pin 1 - Common
Pin 2 - Signal
Pin 3 - Sensor detection and current source
Note: Because the following connectors are effectively inputs/outputs, the particular
program of the product/application specific program installed may use these ports for
specific signals, other than their common use (described below).
CN12 - Auxiliary “Hold” (Stop) Port (Typical)
Pin 1 - Common
Pin 2 – “Hold” (Stop) (digital input active LOW)
Pin 3 – Port active recognition
Note:
When the “GSP” control is initially powered-up, it looks to see if pins 1 & 3 are in a closed circuit,
thereby indicating a device/signal using this port. If the control does not see pin 3 connected to
common, it assumes that nothing is connected to this port and will not look for the auxiliary “Hold”
(stop) signal. Therefore, any auxiliary “Hold” (stop) device that is connected to the control
after it has been powered-up will be ignored. After the microprocessor has recognised that a
device is connected to this port, it will activate the “Hold” (stop) command when pin 1 & 2 are in a
closed circuit.
CN13 - Limit Switch Monitoring Input (Typical)
Pin 1 - Common
Pin 2 - Reverse limit switch
Pin 3 - Center limit switch
Pin 4 - Forward limit switch
Pin 5 - Spare (not used)
Note:
Limit switches are to be wired in the “normally closed” configuration to allow normal use. When the
“GSP” control is initially powered-up, it looks to see if either the forward or reverse limit switches are
in closed circuit to common. If the control does not see either of pins 2 or 4 connected to common,
it assumes that no limit switches are in use and will not look for further signals. Therefore limit
switches that are connected to the control after it has been powered-up will be ignored. After
the microprocessor has recognised that limit switches are being used, it will disable any travel in the
relevant direction to that of an open circuit.
