4 INSTALLATION, WIRING AND MAINTENANCE OF THE PRODUCT
4.4 Checking installation and wiring
4.4.1 Items to check when installation and wiring are completed
Check the following points when completed with the QD75 installation and wiring.
Is the module correctly wired? ... "Connection confirmation"
With "connection confirmation", the following three points are confirmed using GX
Configurator-QP's connection confirmation function. (GX Configurator-QP is
required for this "connection confirmation".)
Configurator-QP's connection confirmation function. (GX Configurator-QP is
required for this "connection confirmation".)
Are the QD75 and servo amplifier correctly connected?
Are the servo amplifier and servomotor correctly connected?
Are the QD75 and external device (input/output signal) correctly connected?
With this "connection confirmation", "whether the direction that the QD75
recognizes as forward run matches the address increment direction in the actual
positioning work", and "whether the QD75 recognizes the external input/output
signals such as the near-point dog signal and stop signal" can be checked.

positioning work", and "whether the QD75 recognizes the external input/output
signals such as the near-point dog signal and stop signal" can be checked.
Refer to GX Configurator-QP Operating Manual for details on "Connection
confirmation".
Note that GX Developer (SW6D5C-GPPW-E or later) 1 may also be used to
"confirm the connection between the QD75 and external device (I/O signals).
For details, refer to Section 13.5 "External I/O signal monitor function" and GX
Developer Operating Manual.

1: For the QD75P N/QD75D N, external I/O signals cannot be monitored on GX Developer. Use the
system monitor of GX Works2. For details on the system monitor of GX Works2, refer to GX Works2

Important
If the QD75 is faulty, or when the required signals such as the near-point dog signal and stop signal are
not recognized, unexpected accidents such as "not decelerating at the near-point dog during machine
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.
