5.1.8 Connectors and Wiring Notes
Note 1
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 2 (SS500/600 drives only)
The enable (EN) pin, TB502 pin 12 or TB506 pin 17/18, 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 3
Each of the encoder output pins on TB506 is buffered pass-through. The encoder channel A pin on
TB504, for example, is buffered and routed to the encoder channel A pin on TB506 inside the
SimpleServo. If you require encoder information, wire your controller to TB506. The encoder and Hall
sensor feedback from the motor must be wired to the 15-pin Type D receptacle (connector) through the
feedback cable.
Note 4
The complement of A is sometimes written as not A. The B, C and Z encoder channels are annotated in a
similar fashion.
Note 5
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.
The encoder needs to have power supplied to it. A front-end controller, as well as the SimpleServo, has a
+5 VDC supply voltage that may be used to power the encoder. The SimpleServo contains patent-
pending automated switching circuitry which will power the encoder from a front-end controller if it is
present (through the ENC+ pin). If no supply voltage is present at the ENC+ pin, the SimpleServo will
switch its internal power (+5 VDC supply) to the encoder.
