Maintenance Input
If the signal input circuit is short-circuited, the Enable switch (DSW) and the Safety Plug are
disabled.
Usually, use the system with this signal circuit open (nothing connected).
If the circuit for this signal must be used for an unavoidable reason, be sure to use a switch
with a key that is kept under the care of the system manager.
• This signal is used only for maintenance by YASKAWA's service person-
nel.
For your safety, never use this input for any purpose.
Failure to observe this instruction may cause major disaster.
NOTE
When the maintenance input is short-circuited, the playback is performed at a safe speed
in the FST status (FST: Full Speed Test).
