Mitsubishi Electronics FR-A500L instruction manual How to use terminals STOP, CS and PC

INSTALLATION AND WIRING

5)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 leakage current.

(4) How to use terminals “STOP”, “CS” and “PC”

1)Using the “STOP” terminal

A connection example (for sink logic) for self-holding the start signal (forward rotation, reverse rotation) is shown on the right.

2)Using the “CS” terminal

This terminal is used to perform automatic restart after instantaneous power failure and commercial power supply-inverter switch-over operation.

<Example: Automatic restart after instantaneous power failure in sink logic> Connect terminals CS-SD and set a value other than “9999” in Pr. 57 “coasting time for automatic restart after instantaneous power failure”.

3)Using the “PC” terminal

This terminal can be used as 24VDC power output using SD as a common terminal. Specifications: 18V to 26VDC, 0.1A permissible current

Note that the wiring length should be within 30m. Do not short terminals PC-SD.

When terminal PC is used as a 24V power supply, leakage current from transistor output cannot be prevented.
