A.1
Rear Panel Motor Control Connector
Note. If the motor control connector is not used, the terminator supplied must be fitted.
The ‘Motor Control’ connector provides digital (TTL) signals for use with an external
control panel, e.g. remote jogging capabilities, emergency stop button etc. The pin
functions are detailed in Fig. A.1 and in each case must be referenced to the indicated
return pin for the signal to be true.
Notes.
*
Jog inputs are opto-coupled and must be short circuit to User 0V (pin 9) in order
to function.
** Channel enable inputs are non-driveable and require a
closed contact to the associated return pin in order to function.
‡
User Trig In is TTL I/P compatible, User Trig Out is TTL O/P compatible - see Fig.
A.2 and Fig. A.3.
† Not used on single channel controllers
