Retention time of starting DWELL frequency
F02.02 defines the DWELL frequency of the inverter at start.
F02.03 is the retention time of starting DWELL frequeny
(F02.02) refers to the hold time when the inverter in the
starting process.
• The start should be delayed according to F02.01 setting
when the starting command is enabled. Then start
according to F02.00 setting mode.
• Only when F02.00 = 0 or 1 will F02.02 and F02.03 be
enabled.
• Set F02.02 or F02.03 as 0, the starting DWELL
frequency is disabled.

F02.04 is a percentage of the inverter’s rated
current. To set the current value of the DC
braking at start and at stop.
• If setting is higher than tenfold of motor’s
rated current, the injection current value
is tenfold of the motor’s rated current.
• The DC braking current is valid to both
start and stop DC braking.
F02.05 = 0.0s, there is no DC braking
process at start.
• Only when F02.00 = 1 will F02.05 be
enabled.
F02.06 Reserved
Speed search mode based on current
0: From the max. output frequency to start speed searching.
1: From the stopping moment frequency to start speed searching.
F02.08 Setting reference current for speed search 0
100 (motor’s rated
Set the motor injection current.
Acc./Dec. time of the speed search
Frequency rate of decline follows the deceleration time at speed searching. F02.06 = 1 (speed
searching based on current) is enabled.
Waiting time of speed search
The start should wait for a time according to F02.10 setting when the starting command is enabled.
Then start speed searching.
V/f ratio of speed search
V/f ratio of speed search = F02.11 × motor’s rated voltage / motor’s rated frequency.
