4 INSTALLATION, WIRING AND MAINTENANCE OF THE PRODUCT
4.4 Confirming the installation and wiring
4.4.1 Items to confirm when installation and wiring are completed
Check the (1) and (2) points when completed with the AD75 installation and wiring.
(1) Does the AD75 operate correctly? ... "Single module test"
With the "single module test", correct operation of the AD75 is confirmed by the
LED displays on the AD75. (Change the mode switch following the procedures
given in section "4.4.2 Single module test", and confirm the details displayed on
each mode LED.)
Check that there are no faults in the AD75 with the single module test.
(2) Is the module correctly wired? ... "Connection confirmation"
With "connection confirmation", the following three points are confirmed using the
GX Configurator-AP's connection confirmation function. (The GX Configurator-AP
is required for this "connection confirmation".)
•
Are the AD75 and servo amplifier correctly connected?
•
Are the servo amplifier and servomotor correctly connected?
•
Are the AD75 and external device (input/output signal) correctly connected?
With this "connection confirmation", "whether the direction that the AD75
recognizes as forward run matches the address increment direction in the actual
positioning work", and "whether the AD75 recognizes the external input/output
signals such as the near-point dog signal and stop signal" can be checked.
In this manual (1) "Single module test" is explained. Refer to the GX
Configurator-AP Operating Manual for details on (2) "Connection confirmation".
Important
If the AD75 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
zero point return and colliding with the stopper", or "not being able to stop with the stop signal" may
occur.
The "single module test" and "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.
