3.4 Confirming while the Power is ON
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
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.
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
(Y80 to Y8B) allocated to each axis turn ON in user programs. In addition, the valid logic of
over limit input can be changed in the parameter setting menu of "Configurator PMX".
3.
Using the JOG operation, check to see if the over limit switch is functioning properly.

3.4.4 Checking the Operation of the Near Home Switch and Home Switch
1.
Check if the near home input is loaded as input signals on the PLC properly by operating
the home input and near home input forcibly.
2.
Start the home return by inputting the home return program, and check if the operation
transits to the deceleration operation by the near home input.
Points to check
Set the valid logic which enables the home input and near home input in the parameter
setting menu of "Configurator PMX".
