Starting frequency and start-time hold function
It is possible to set the starting frequency and hold the set starting frequency for a certain period of
Set these functions when a starting torque is needed or the motor drive at start needs smoothing.
Starting frequency setting (Pr. 13)
● The frequency at start can be set in the range of 0 to 60 Hz.
● Set the starting frequency at which the start signal is turned ON.
The inverter does not start if the frequency setting signal is less than the value set in Pr. 13.
For example, while Pr. 13 = 5 Hz, the inverter output starts when the frequency setting signal
reaches 5 Hz.
Start-time hold function (Pr. 571)
● This function holds during the period set in Pr. 571 and the output frequency set in Pr. 13 "Starting
● This function performs initial excitation to smooth the motor drive at a start.
