4.3 Confirming the Installation and Wiring

4.3.1 Items to confirm when installation and wiring are completed

Confirm the wiring after installation and wiring.
Confirm the following points in the buffer memory using GX Developer.
• Are the servo amplifiers correctly connected?
• Are the servo amplifiers and servomotors correctly connected?
• Are the external devices (input signals) correctly connected?
• Are the forced stop inputs correctly connected?
Connection with the external devices (input signals) or forced stop inputs can also be
confirmed by the following monitor data of GX Developer.
• Connection with the external devices (input signals)....
• Connection with the forced stop input...........................
Important
If the QD74MH is faulty, or when the required signals such as the proximity dog
signal and stop signal are not recognized, unexpected accidents such as "not
decelerating at the proximity dog during OPR and colliding with the stopper", or "not
being able to stop with the stop signal" may occur.
The "connection confirmation" must be carried out not only when structuring the
positioning system, but also when the system has been changed with module
replacement or rewiring, etc.
