4 INSTALLATION, WIRING AND MAINTENANCE OF THE PRODUCT
4.6 Confirming the installation and wiring
4.6.1 Items to confirm when installation and wiring are completed
Check the (1) and (2) points when completed with the D75P2 installation and wiring.
(1) Does the D75P2 operate correctly? ... "Single module test"
With the "single module test", correct operation of the D75P2 is confirmed by the
LED displays on the D75P2. (Change the mode switch following the procedures
given in section "4.7 Single module test", and confirm the details displayed on
each mode LED.)
Check that there are no faults in the D75P2 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 D75P2 and servo amplifier correctly connected?
Are the servo amplifier and servomotor correctly connected?
Are the D75P2 and external device (input/output signal) correctly connected?
With this "connection confirmation", "whether the direction that the D75P2
recognizes as forward run matches the address increment direction in the actual
positioning work", and "whether the D75P2 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 D75P2 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.
