Starting frequency and start-time hold function
You can set the starting frequency and hold the set starting frequency for a certain period of time.
Set these functions when you need the starting torque or want to smooth motor drive at a start.
Holding time at start
The above parameters can be set when Pr. 160 "User group read selection" = 0.
Starting frequency setting (Pr. 13)
The motor is started with the specified start frequency as soon as the frequency inverter re-
ceives a start signal and a frequency setting that is greater than or equal to the preset starting
The inverter will not start if the frequency setting signal is less than the value set in Pr. 13.
When 5Hz is set in Pr. 13, the motor will not start running until the frequency setting signal
Note that when Pr. 13 is set to any value lower than Pr. 2 "Minimum frequency", simply
turning on the start signal will run the motor at the preset frequency even if the
command frequency is not input.
Setting Range Description
Frequency at start can be set in
the range 0 to 60Hz.
You can set the starting fre-
quency at which the start signal
is turned on.
