Maximum output frequency:
Parameter 01-00=F, maximum output frequency set by 01-02, 01-00 ≠ F, maximum output frequency determined by
V/F curve selected (50.0 / 60.0 / 90.0 / 120.0 / 180.0).
Example
: 01-00=0 (50Hz (maximum output frequency), 05-02=10 Hz (multi-step speed 0), 05-17=5.0s (Acceleration
time), 05-18=20.0 sec. (Deceleration time).
Acceleration time calculation formula
5.0 x 10 Hz
Time it takes to reach set frequency =
= 1.0 sec.
50 Hz
Deceleration time calculation formula
20.0 x 10 Hz
Time it takes to reach set frequency =
= 4.0 sec.
50 Hz

If the run command is cycled on and off, acceleration and deceleration time (a – f) is calculated based on the active
speed command as follows:
