means of combined setting, the inverter’s frequency output can be controlled by
multiple channels.

6.3 Auxiliary running parameter group
F2.00 Start frequency
F2.01 Start frequency duration
Setting range: 0.0 ~ 50.0Hz
Setting range: 0.0 ~ 20.0Sec
This functional parameter group is used to define characteristics relevant with start
mode. See Figure 6-12.
For the system with large inertia, heavy load and high requirements of start torque,
the start frequency can effectively overcome the problem of difficulty start. The
start frequency duration (parameter code [F2.01])) means the running duration at
the start frequency, and can be set according to actual requirements. When it is set
to 0, the start frequency is void.
