Motor overspeeding detection
The Overspeed occurrence (E.OS) is activated when the motor speed exceeds the overspeed detec-
tion level. This function prevents the motor from accidentally speeding over the specified value, due
to an error in parameter setting, etc.
The maximum motor frequency is set in Pr. 702 "Maximum motor frequency." When Pr. 702 = "9999
(initial value)", the Pr. 84 "Rated motor frequency" setting is applied as the maximum motor
frequency.

If the motor rotation speed exceeds the speed set in
Pr. 374 during PM motor control, Overspeed
occurrence (E.OS) occurs, and the inverter output is
shut off.
9999
During PM motor control, E.OS occurs when the speed
exceeds "the motor maximum fre 10 Hz"
