Connectors and Wiring Notes
Note 1
The enable (Enable) pin, TB2 pin 9, must be wired to one of the output terminals on the front-end
controller, i.e., if the controller is present, it must supervise the enable function on the SimpleServo. The
SimpleServo will accept open-collector outputs for use as a switch, TTL or CMOS outputs (5V)
programmed for active low operation.
Note 2
An external pulse train signal (for "step") supplied by an external device, such as a PLC or stepper
indexer, can control the speed and position of the servomotor. The speed of the motor is controlled by the
frequency of the step signal, while the number of pulses that are supplied to the SimpleServo determines
the position of the servomotor. "DIR" input controls direction of the motion.
Note 3
The complement of A is sometimes written as not A. The B, C and Z encoder channels are annotated in a
similar fashion.
Note 4
The encoder needs to have power supplied to it. The SimpleServo has a +5 VDC supply voltage that may
be used to power the encoder.
WARNING!
Use only +5 VDC encoders. Do not connect any other type of encoder to the
SimpleServo reference voltage terminals. When using a front-end controller, it is
critical that the +5 VDC supply on the front-end controller NOT be connected to the +5
VDC supply on the SimpleServo, as this will result in damage to the SimpleServo.
