INSTALLATION AND WIRING
3) Source logic type
•
In this logic, a signal switches on when a current flows into the corresponding signal
input terminal.
Terminal PC is common to the contact input signals. Terminal SE is common to the
open collector output signals.
•
When using an external power supply for transistor output, use terminal SD as a
common to prevent misoperation caused by undesirable current.
(5) How to use the STOP signal
The following connection example shows how to self-hold the start signals (forward
rotation, reverse rotation).
Use Pr. 180 to Pr. 183 (input terminal function selection) to assign the STOP signal.
