 Overspeed error detection
If the output frequency exceeds the overspeed protection level, the inverter detects the overspeed
protection alarm (alarm code: 1B) and shuts off (trips) inverter output.
• Conditions that cause an overspeed protection alarm
Over Speed Detection Level (3014Hex-24Hex) = 999
<Forward rota-
tion side>
<Reverse rota-
tion side>
Over Speed Detection Level (3014Hex-24Hex) = Other than 999
Overspeed protection level = 1st Maximum Output Frequency (3004Hex-04Hex)/2nd Maximum
Output Frequency (3009Hex-02Hex) × Over Speed Detection Level (3014Hex-24Hex) (%)
 Speed mismatch/excessive speed deviation
If the state where the difference between the frequency reference and the actual frequency ex-
ceeds the set value of Speed Agreement / Speed Deviation Error Hysteresis Width
(3014Hex-16Hex) continues for Speed Agreement / Speed Deviation Error Detection Timer
(3014Hex-17Hex), this state is judged to be a speed mismatch/excessive speed deviation, post-de-
tection processing is performed according to the setting of Speed Deviation Error Processing Se-
lection (3014Hex-18Hex).
