• Clears the alarm condition.
• This input cannot clear some alarms.
• For details, refer to P.6-3 When in Trouble “Protective function”, P.2-86 “(8) Alarm Display”
and P.7-25 “Display of Battery Alarm”.

Caution
• Ignores the positional command pulse.
• When using this feature, set Pr5.18 “Invalidation of command pulse inhibition input” to 0.
This function can be assigned to only SI10. Allocation of this function to any other pin will
cause an error.
When INH input is ON, the deviation will be caused between the
positional command
administrated by controller and internal positional command
from the fliter that receives the
positional command from servo drivers, and orginal
location before being input INH positional
command
will be lost. Therefore, it is supposed to reset the orignial location when it needs to
restart return to origin action.
