Figure. 5-1-3 Starting frequency and starting time
1. Starting frequency is not restricted by the frequency lower limit.
2. If reference frequency is lower than starting frequency during acceleration, the inverter will run at zero-speed
P1.03 DC braking current at start This value depends on the inverter model [0.0%]
P1.04 DC braking time at start Setting range: 0.0~30.0s [0.1s]
Notes:
P1.03 and P1.04 are only active when P1.00 is set to 1 (start mode 1 is selected), as shown in Figure. 5-1-1.
In V/F mode, 100.0% corresponds to the rated current of the motor; in vector mode, the starting DC braking
current is determined by P8.00 pre-excitation current compensation coefficient (100.0% corresponds to
no-load current of the motor).
The set upper limit of the starting DC braking current is 80% of the rated current of the inverter or the smaller
rated current of the motor.
When the starting DC braking time is 0.0s, there is no DC braking process.
Tips Before using DC braking function, the rated parameters of the motor must be correctly set.
P1.05 start preset frequency Setting range: 0.00 ~ maximum frequency [0.00Hz]
P1.06 preset frequency hold time Setting range: 0.0 ~ 3600.0s [0.0s]
