F6-02
Setup range 1~ 100
When it is in the mode of rotation speed tracking restart, select the fastness
and slowness of the rotation speed tracking. The higher this parameter value
is, the faster the tracking speed is. But too high value may result in unreliable
tracking.

To ensure the torque at the start of driver, it needs to set a proper start
frequency. In addition, to set up flux at the time of motor start, it needs to start
speed-up after the start frequency is kept for a certain period of time. The
start frequency value F6-03 is not limited by the frequency lower limit.
When the frequency setup value (frequency source) is lower than the start
frequency, the driver cannot be started and is in the standby status. When the
forward rotation and reverse rotation is being switched each other, the start
frequency retention time is inenabled. The retention time is not included in
the speed-up time but in the running time of simple PLC.
Example 1:
F0-03=0 Frequency source is digital setup
F0-08=2.00Hz Digital setup frequency is 2.00Hz.
F6-03=5.00Hz Start frequency is 5.00Hz.
F6-04=2.0s Start frequency retention time is 2.0s.
At this time, the driver is in the standby status, and the output frequency of
the driver is 0Hz.
Example 2:
F0-03=0 Frequency source is digital setup.
F0-08=10.00Hz Digital setup freqeuncy is 10.00Hz.
F6-03=5.00Hz Start frequency is 5.00Hz.
F6-04=2.0s Start frequency retention time is 2.0s.
At this time, the driver accelerates to 5Hz and further to setup freuqency of
10Hz in 2s.
