5.3 Description of Function Codes
5-78
Under vector control with speed sensor
At the startup, the inverter first starts at the “0” speed and accelerates to the starting frequency according to the
specified acceleration time. After holding the starting frequency for the specified period, the inverter again
accelerates to the reference speed according to the specified acceleration time.
The inverter stops its output when the reference speed or actual speed (specified by F38 under vector control with
speed sensor only) reaches the stop frequency specified by F25.
Specifying the holding time for the starting frequency compensates for the delay time for the establishment of a
magnetic flux in the motor; specifying that for the stop frequency stabilizes the motor speed at the stop of the
inverter.
■ Starting frequency 1 (F23)
F23 specifies the starting frequency at the startup of an inverter.
• Data setting range: 0.0 to 60.0 (Hz)
■ Starting frequency 1 (Holding time) (F24)
F24 specifies the holding time for the starting frequency 1.
• Data setting range: 0.00 to 10.00 (s)
■ Stop frequency (F25)
F25 specifies the stop frequency at the stop of the inverter.
• Data setting range: 0.0 to 60.0 (Hz)
■ Stop frequency (Holding time) (F39)
F39 specifies the holding time for the stop frequency.
• Data setting range: 0.00 to 10.00 (Hz)
