History...The error will be stored in the error history.
Can be cleared...To cancel the error, use the alarm clear input (A-CLR).
If the alarm clear input is not effective, turn off power, remove the cause of the error and then turn on
power again.
Immediate stop...Instantaneous controlled stop upon occurrence of an error.
(Setting of “Pr.5.10 Sequence at alarm” is also required.)

*1
:
When Err16.0 “Overload Protection 1”is activated, error can be cleared about 10 seconds after the occurrence.
*2
:
When Err40.0 “Absolute System Down Error protection,” or Err42.0 “Absolute Overspeed Protection” occurs, the
error is unable to be cleared unless Absolute Clear is performed.
*3
:
Immediate stop refers to alarms which result in an immediate stop when setting is made to 4 to 7 in Pr5.10 “Sequence
at alarm” are shown. For the detail of an immediate stop, see 6-5-4 “Sequence at alarm.”
*4
:
Err 16.0 “Overload protection,”can be switched to responsive/non-responsive by switching bit 11 of “Function
expansion setting 2” of Pr 6.47. Set to non-responsive at time of shipment.
