Chapter 5 Power Activation and Operational Tests
PAGE 5-2
5-1 Items to be Checked Before Power Activation
(1) Check connection between tool and Controller
Connect the cable between the tool and the controller securely.
If there is a movable part in the path of the cable, check whether or not the cable receives stress by
actually moving the movable part. If the cable receives stress, change the wiring method.
(2) Check wiring for I/O signals
Connection with the external control equipment must be made at the terminal block on the rear panel
of the controller.
(3) Use a dedicated cable for power source.
Check that the earth line is connected without fail.
(4) Check the power source voltage
Check that the input power source voltage of the controller is in a range of single-phase 100V AC ~
240V AC.
The recommended wiring size for the primary power is no less than 1.25mm
2
. If lowering of the
power source voltage occurs due to using a thin wiring, etc., a source voltage error will occur.
Lowering of voltage may occur if a thin wire is used across a long distance.
BE SURE TO CONFIRM THE ABOVE ITEMS BEFORE POWER ACTIVATION.
