Detailed instruction of parameters
After the users select the corresponding ACC/DEC time,
the combining 16 binary bit will change into decimal bit,
and then set the corresponding function codes.
Setting range: -0x0000–0xFFFF
0: Restart from the first stage; stop during running
(cause by the stop command, fault or power loss), run
from the first stage after restart.
1: Continue to run from the stop frequency; stop during
running (cause by stop command and fault), the VFD will
record the running time automatically, enter into the
stage after restart and keep the remaining running at the
setting frequency.
0: Seconds; the running time of all stages is counted by
second
1: Minutes; the running time of all stages is counted by
minute
0x00–0x11
LED ones:
0: Input phase loss protection disable
1: Input phase loss protection enable
LED tens:
0: Output phase loss protection disable
1: Output phase loss protection enable
0: Enabled
1: Disabled
Setting range: 0.00Hz/s–P00.03 (the Max. frequency)
After the power loss of the grid, the bus voltage drops to
the sudden frequency-decreasing point, the VFD begin
to decrease the running frequency at P11.02, to make
the VFD generate power again. The returning power can
maintain the bus voltage to ensure a rated running of the
VFD until the recovery of power.
