Motor overload protection gain
P9-01
Setting range
P9-00 = 0: No motor overload protection function may present a risk of damage to the motor overheating, the proposed
increase thermal relay between the inverter and the motor;
P9-00 = 1: the frequency converter according to the motor overload inverse time curve to determine whether the motor is
overloaded. Motor overload inverse time curve: 220% × (P9-01) × motor rated current for 1 minute, the alarm of motor
overload fault; 150% × (P9-01) × rated motor current, the motor 60 minutes the alarm overload.
User according to the actual motor overload, set the correct value of P9-01, this parameter is set too easily lead to motor
overheating and the risk of damage to the inverter not alarm!
P9-02
Motor overload warning coefficient
This function is used before the motor overload fault protection, through DO to the control system a warning signal. The
warning coefficient is used to determine, before the motor overload early warning extent. The higher the value the smaller
the amount of advance warning.
When the inverter output current cumulative amount greater than overload inverse curves and P9-02 product, multifunction
drive DO digital output "motor overload pre-alarm" ON signal.
P9-03
P9-04
Overvoltage stall protection voltage
During the deceleration, when the DC bus voltage exceeds the overvoltage stall protection voltage, the inverter stop
deceleration is maintained at the current operating frequency, voltage drops until the bus continues to decelerate.
Overvoltage stall gain for adjusting during deceleration, the drive capacity in suppressing the pressure. The bigger the value,
the stronger the ability to suppress the overvoltage. Without overvoltage occurs, the gain is set as small as possible.
For small inertia load, over-voltage stall gain should be small, otherwise the system dynamic response slow. For large
inertia loads, this value should be large, otherwise the suppression ineffective, overvoltage fault may occur.
Overvoltage stall when the gain is set to 0, the cancellation of overvoltage stall function.
