Basic Wiring
WARNING
The CX-1010 should only be installed by a qualified electrician.
Hazardous voltages may cause severe injury, death or equipment damage.
The CX-1010 General Wiring Diagram illustrates the complete power and signal
wiring for the CX-1010 control. Not all of the connections will be required for your
application. Refer to the CX-1010 Technical Reference Manual for complete
installation and wiring instructions.
The following instructions describe the basic wiring required for the master and
follower modes of operation:
Power (J4 pins 1,2,3)
Position the power selector switch on the back of the CX-1010 to configure the
power supply for 115 or 230 VAC. Wire the power as shown in the diagram for
115 or 230 VAC.
WARNING
Applying 230 VAC power with the power selector switch in
the 115 position will result in damage to the CX-1010 controller.
Run/Stop Logic (J6 pins 1,2,3,4,5)
In order to put the CX-1010 into "Run", the F-Stop, R-Stop and H-Stop inputs
must be shorted to common, usually through a normally closed pushbutton. The
Run input must then be temporarily shorted to common, usually through a normally
open pushbutton. Thereafter, opening any of the Stop inputs will cause the
CX-1010 to stop.
Speed Command (J3 pins 1,2)
The speed command is a two wire connection between the CX-1010 and the motor
drive. Insure that the isolated common (J3 pin 2) is not used elsewhere.
Drive Enable (J2 pins 1,9,10)
When this digital output of the CX-1010 is wired to the appropriate control input of
the subject drive, it allows the CX-1010 to enable and disable the drive as required.
A low voltage pilot relay is usually required.
Frequency Inputs (J5 pins 1 thru 11)
Both the master and follower modes of operation require the feedback frequency
input for closed loop control. The follower mode also requires the lead frequency
input connection. When using nondifferential (single-ended) quadrature sensors,
connect phase A to pin 2 (7), phase B to pin 4 (9) and common to pin 6 (11). Refer
to the CX-1010 Technical Reference Manual for detailed diagrams illustrating
connections for various types of frequency sensors.
