3.4.2 Checking the installation of the external safety circuit
Make a check on the safety circuit recommended by the motor manufacturer, which includes a
check on the disconnection of the power supply to the motor driver with CW and CCW drive
inhibition switch input from an external circuit.
3.4.3 Checking the safety circuit based on the unit
Procedure 1
Using forced operation of the over limit switch, check to see if the over limit input is being
properly taken into the PLC side.
Procedure 2
If necessary, input a program to start the JOG operation. Then operate the over limit input to
check whether the motor will stop. The limit stop will be effective when output signals (Y860 to
Y867) allocated to each axis turn ON in user programs. The valid logic of limit input can be
changed in the parameter setting menu of "Configurator PMX".
Procedure 3
Using the JOG operation, check to see if the over limit switch is functioning properly.
