Starting frequency
It is possible to set the starting frequency.
Set this function 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.

NOTE
• The inverter does not start if the frequency setting signal has a value lower than that of Pr.13.
For example, while Pr.13 = 5 Hz, the inverter output starts when the frequency setting signal reaches 5 Hz.
CAUTION
• Note that when
