Ref. Code Function Description Setting Range [Default]
F02.02 Frequency setting of DWELL starting 0.00 - F00.08 [0.00Hz]
Frequency keeping time of DWELL starting
At start-up, the set output frequency is temporarily maintained to prevent the motor from stalling.
For motor-driven load, When a brake is installed, when the brake
moves slowly, use the start-up DWELL function to accelerate
after the brake is fully open to prevent brake friction.
• During Acc., when the setting frequency matches the
frequency set by F02.02, the output frequency is kept
accelerating after the time set in F02.03.
• F02.02 = 0 or F02.03 = 0, DWELL frequency in starting is not
valid.
F02.04 DC brake current setting 0 - 100% (inverter rated current)
F02.05 Starting DC braking time 0.00 - 60.00 [0.00s]
F02.04 is the percentage of the inverter's rated
current. Set the DC braking start and stop DC braking
current value.
• If the set DC brake current is more than 5 times the
rated motor current, the injected current is 5 times
the rated motor current.
• DC braking current is valid for both DC braking and
DC braking.
F02.05 = 0, no DC braking procedure.
• F02.05 is valid only when F02.00 = 1.
F02.13 Stoping mode selection 0 - 2 [2]
0: Reserved.
1: Stop freely.
• After the inverter receives the stop command, the output will be terminated immediately. The load will
stop freely according to the mechanical inertia.
2: Dec. stop + DC brake.
• After the inverter receives the stop command, it will decrease the output frequency according to the Dec.
time. When the frequency set by F02.16 is reached, DC braking will start.
• Stop DC braking function see F02.16 - F02.18. For Dec. time see F03.01 - F03.02.
