4.4.2 Check on External Safety Circuit

Make a check on the safety circuit recommended by the motor manufacturer, which include 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.

4.4.3 Check on Safety Circuit with Positioning Unit

Step 1
Forcibly operate the over limit switch for the positioning safety circuit and check that the
positioning unit correctly receives limit input.
The state of limit input can be checked with the input contact. The valid logic of limit input can
be changed in the parameter-setting menu of the Configurator PM7.
Step 2
Input a program, if necessary, to perform the JOG operation of the positioning unit. Then
forcibly operate limit input and check that the motor will come to a stop.
You can use the tool operation of the Configurator PM7 to make a check without using a
program.
Step 3
Perform the JOG operation of the positioning unit and check that the over limit switch will
operate normally.
