3.1 Pin Assignments
Pin assignments for the male D-Type connector on the motor flying lead are described below..
Fig. 3.1 Output Connector
3.2 Description of connections
Limit Ground
: a common ground for both the forward and reverse limit switches.
CCW Limit
: the counter clockwise (reverse) limit prevents over driving of the actuator at its minimum extension.
CW Limit
: the clockwise (forward) limit prevents over driving of the actuator at its full extension.
When using a third party controller, the inputs must be connected via a 10 k pull up resistor as shown below. When either
switch operates, the associated input is pulled to ground and the TTL buffers switch.
Fig. 3.2 ZST200 Limit Switch Circuit
Motor Phases
: supplies 15 VDC 1A to the motor of the actuator.
