Minimum motor speed frequency and hold function at motor start up
Set the frequency where the PM motor starts running.
Set the deadband in the low-speed range to eliminate noise and offset deviation when setting a fre-
quency with analog input.
Starting frequency setting (Pr. 13)
● The frequency where the PM motor starts running can be set in the range of 0 to 60 Hz.
● While the frequency command is less than the Pr. 13 "Starting frequency" setting, the PM motor
When the frequency command reaches the set frequency or higher, the PM motor accelerates
according to the Pr. 7 "Acceleration time" setting.
Under induction motor control (under V/F control, Advanced magnetic flux vector control, Real
sensorless vector control, and vector control), the output starts at the frequency set in Pr. 13.
Under PM sensorless vector control, the output always starts at 0.01 Hz.
The inverter output does not start when the frequency-setting signal is less than Pr. 13. For exam-
ple, while Pr. 13 = "20 Hz", the inverter output starts when the frequency setting signal reaches
