Emergency Stop at Alarm
If an alarm occurs that requires an immediate stop, setting the following parameters will control the motor to
immediately stop it.

To set up the states during the deceleration and after the stop when
an alarm occurs.
The immediate stop is valid when the parameter is set to either 4, 5,
6 or 7.

Overspeed level
0
20000
r/min
If the motor speed exceeds the value set with this parameter, Err26.0
“Over-speed protection” occurs.
If the value is set to 0, the overspeed level will be set at the
maximum number of motor revolution multiplied by 1.2.

Emergency stop time at
alarm
0
1000
ms
To set the allowable time for the immediate stop to complete when
there is an alarm. The time exceeding the value set for this
parameter will force a state of alarm.
If 0 is set for this parameter, the immediate stop doesn’t do, and
become an alarm state immediately.

r/min
If the motor speed exceeds the value set for this parameter during an
immediate stop which has been caused by an alarm, Err26.1 “2
nd
over-speed protection” will occur.
If the value is set to 0, the overspeed level will be set at the
maximum number of motor revolution multiplied by 1.2.
(2) Item
Immediate stop operation when an alarm requiring an immediate stop occurs
(Note) To protect against runaway upon instantaneous stopping, specify an allowable excessive speed level in
Pr6.15 “2
nd
over-speed level setup”. If 2
nd
excessive speed protection, which is an error not applicable to
instantaneous stopping, is activated, it immediately leads to error tripping. However, if set lower than
Pr5.13 “Over-speed level setup”, a fast shutdown will not be executed due to Err26.1 “2
nd
over-speed
protection” that occurs before Err26.0 “Over-speed protection”.
If Err26.0 and Err26.1 are detected at the same time, Err26.0 will be displayed but a fast shutdown will
not be executed due to Err26.1 that is internally occurring.
