Handling Precautions
1. Precautions on Wiring
[1] It should be handled according to the operation manual for the XSEL-P/Q or R/S controller and
RC controller. Make sure to implement countermeasures against noise for electric devices sharing
the same power supply or within the same equipment.
[2] RC controllers shall be connected to the same 24-VDC power as a general rule. Our PS24
products can be connected in parallel, but if commercially available DC power supply units are to
be used, connect each controller’s power supply to common ground (0 V).
[3] Wire the emergency stop to the X-SEL-P/Q controller and each RC controller in the same system
such that the emergency stop signal is input to the X-SEL-P/Q controller and each RC controller at
the same time.
If a command from the X-SEL controller enters in the emergency stop status on the RC controller
side only when the servo is turned on, the error No. 458 "Pulse train driver servo OFF error during
pulse I/O board axis servo ON” occurs.
