PULSE LOCKOUT OUTPUT (Pins K & L)
Function: Permits the 9700W to pass a pulse signal to another device. The signal from these pins directly
follows the Pulse Lockout Input signal.
Electrical: This is an open collector output, Pin K is high, Pin L is low.
REMOTE SPEED INPUT (Pins M & N)
Function: The 9700W can be configured to permit the travel speed to be set by a remote analog input
signal. The signal is supplied to these pins from the remote device.
Electrical: Requires 0 to 10VDC input signal. Pin M is high, Pin N is low. Input impedance is 60K.
S3 CONNECTOR
The S3 connector is used to connect the 9700W control to the motor which it is controlling. Miller Welding
Automation can provide standard connecting cables to be connected to the S3 connector on the 9700W
control. If you need to provide your own cable, it should be fitted with the following:
Amphenol plug 97-3106A-22-19P
Cord Grip 97-3057-1012-1
Pin Connection Details
Connections should be made as shown below.
Note: Pins E, F, G, H, J, K, L, M, N and P are reserved.
MOTOR OUTPUT CONNECTION (Pins A & B)
Function: To supply voltage to the carriage drive motor. If Pin A is positive voltage with respect to Pin
B, the motor will rotate in a clockwise direction. If it is negative, motor rotation will be
counterclockwise.
Electrical: We supply 90VDC to the motor.
TACHOMETER INPUT (Pins C & D)
Function: To receive a voltage signal from the tachometer mounted on the motor which drives the
carriage. The signal is used to provide digital speed indication on the display and also to provide closed
loop facilities.
Electrical: We accept a 0 to 100VDC signal. The signal is conditioned in the 9700W control.
C. Interconnections
The 9700W control can be connected to other devices to provide more complete control of the welding
process. Standard length cables, complete with the appropriate Amphenol connectors are available from
Miller Welding Automation. Special length cables can be made to order.
