Power ON and OFF, and Items to Check3-63.4.2 Checking the installation of the external safety circuitMake a check on the safety circuit recommended by the motor manufacturer, which includes acheck on the disconnection of the power supply to the motor driver with CW and CCW driveinhibition switch input from an external circuit.3.4.3 Checking the safety circuit based on the unitProcedure 1Using forced operation of the over limit switch, check to see if the over limit input is beingproperly taken into the PLC side.Procedure 2If necessary, input a program to start the JOG operation. Then operate the over limit input tocheck whether the motor will stop. The limit stop will be effective when output signals (Y860 toY867) allocated to each axis turn ON in user programs. The valid logic of limit input can bechanged in the parameter setting menu of "Configurator PMX".Procedure 3Using the JOG operation, check to see if the over limit switch is functioning properly.
