Injection Braking Stop
To use the DC braking force for stopping, set [AF101] DC braking selection to 01, [AF102] Braking
mode selection to 00, [AF106] DC braking time to other than 0.00 second, and [AF105] DC braking
force to any any value. When the frequency output is shut off, DC braking force will be applied.
The braking force is adjusted at the [AF105] DC braking force.
When [AF104] DC braking delay time is set, and if the operation command is turned off and the decel-
erated frequency falls below [AF103] DC braking frequency, the output will be shut off once, and after
[AF104] has elapsed, DC braking will be started.
Precautions for Correct Use
• The operation to be performed when the operation command is switched from the stop com-
mand to the start command varies depending on the setting of [AF107] DC braking/edge or
level selection.
• When setting [AF105] DC braking force and [AF106] DC braking time, pay attention to the
heat generation on the motor.
• Edge mode: [AF107]=00
[AF106] DC braking time setting is given priority, and the inverter performs DC braking for the time
set for [AF106]. After the operation command is turned off, if the output frequency falls below [AF103]
DC braking frequency, DC braking will be applied for the time set for [AF106]. Even if the operation
command is turned on during DC braking, DC braking continues until the time set for [AF106]
elapses. (Ex.1), (Ex.2)
• Level mode: [AF107]=01
Operation commands are given priority. The inverter ignores [AF106] DC braking time and transits to
the normal operation. If the start command is turned on during DC braking, the inverter ignores the
time set for [AF106] and returns to the normal operation. (Ex.3), (Ex.4)
