Setting Range: 0 to 50%
Factory Default: 10%
This sets the excessive speed deviation detection level as a percentage of maximum
output speed (E1-06). Used in conjunction with parameter F1-11 to sense a speed
deviation condition.
Setting Range: 0.0 to 10.0s
Factory Default: 0.5s
This parameter sets the elapsed time for which a speed deviation condition must
exist, before a fault (or alarm) is generated.
A fault (or alarm) signal is output after the deviation between speed reference and the
actual motor speed exceeds the set value of F1-10 and after the time set to F1-11
elapses. The stopping method is set with F1-04. Also, detection is not activated
while accelerating/decelerating or during torque control.
Setting Range: 0.0 to 10.0s
Factory Default: 3.0s
This sets the time for which a PG open condition must exist, before a fault (or alarm)
is generated.
•
The stopping method, when a “PGO” condition is detected, is selected by param-
eter F1-02.
