Data Transfer to MC Unit and Test Operation6-66.3.3 Checking the safety circuit by the PLC unitProcedure 1Check if the input of the over limit switches connected to the servo amplifier is loaded to theunit by operating them forcibly.Points to checkCheck if the limit setting is Enabled, input logic is correct in the parameter setting menu ofCMI.Procedure 2Check if the limit stop is activated at the time of limit input by the tool operation function ofCMI or performing the JOG operation with a program.Procedure 3Using the JOG operation, check if the over limit switch is functioning properly. Operation at Over limit input (Limit is Enabled)Condition Direction Limit status OperationWhen JOG operation isstartedForward Over limit input (+): ON Not executable, Error occurs.Over limit input (-): ON ExecutableReverse Over limit input (+): ON ExecutableOver limit input (-): ON Not executable, Error occurs.During JOG operation Forward Over limit input (+): ON Limit stops, Error occurs.Reverse Over limit input (-): ON Limit stops, Error occurs.
