F02.10 Waiting time of speed search 0.1
5.0s
1.0
The start should wait for a time according to F02.10 setting when the starting command is enabled.
Then start speed searching.
F02.11 V/f ratio of speed search 0.0
100.0%
100.0
V/f ratio of speed search = F02.11 × motor’s rated voltage / motor’s rated frequency.
F02.12 Disposal time after speed search 0.01
5.00s

Complete the establishment of the time from searching the frequency to output the voltage in speed
search process.

0: Decelerate to stop. After the stop command is received, the inverter reduces its output frequency
according to the deceleration time. When the frequency decreases to F02.14 and holds on a time
F02.15 set, it will stop.
• Refer to the parameter F02.14 and F02.15 in the figure.
1: Coast to stop. After the stop command is received, the inverter stops output immediately and the
motor stops under the effects of mechanical inertia.
2: Decelerate to stop with DC braking. After the stop command is received, the inverter reduces its
output frequency according to the deceleration time and starts DC braking when its output frequency
reaches F02.16 setting frequency.
• Refers to parameter F02.16－F02.18 in the figure for the DC braking at stop.
• Refers to parameter F03.00－F03.08 for the deceleration time.
F02.14 DWELL frequency setting at stop 0.00

Retention time of DWELL frequency at stop
F02.14 defines inverter’s DWELL frequency
at stop.
F02.15 is a holding time DWELL frequency at
stop (F02.14) in inverter stop process.
• Only when F02.13 = 0 will it be enabled.
• Set F02.14 or F02.15 as 0, DWELL
frequency at stop is disabled.
DC braking initial frequency at stop
F02.17 DC braking waiting time at stop 0.00
10.00s
0.50
F02.17 is the interval from A to B in the right
figure during deceleration stop process.
• The inverter has no output during the
waiting time. By F02.17 setting the
waiting time, the current overshoot in
the initial stage (point B in the figure )
of braking can be reduced when the
inverter drives a high power motor.
• By F02.04 setting the DC braking
current at stop.
F02.18 = 0.00s, there is no DC braking
process at stop.
• Only when F02.13 = 2 will F02.16－
F02.18 be enabled.
