Func
tions
• Internal DC Injection Braking (A051 = 01)
• Performs DC injection braking to stop the motor without any terminal operation.
To use this function, set the DC injection braking selection (A051) to 01.
• Adjust the DC injection braking power with A054.
• Set the frequency for starting DC injection braking in A052.
• If you set a DC injection braking frequency (A052) below the starting frequency (b082), internal DC
injection braking operates at the starting frequency. Note that setting the DC injection braking
frequency to 0.0 Hz disables internal DC injection braking.
• If the DC injection braking delay time (A053) is set, the output is shut off when the frequency
reaches the level set in A052 during deceleration, and free-run status arises for the specified
period. DC injection braking starts after the set time elapses.
• Below are edge/level operations in internal DC injection braking.
Edge operation: Giving priority to the DC injection braking time (A055), performs DC injection
braking for the specified period.
DC injection braking is activated for the set time in A055 when the output
frequency reaches the set value in A052 after the RUN command (FW) is turned
off.
Even if the RUN command is turned on during DC injection braking, the latter is
effective during the set time in A055.
(Example 5-a), (Example 6-a)
Level operation: Giving priority to the RUN command, shifts to normal operation, ignoring the DC
injection braking time (A055).
If the RUN command is turned on during DC injection braking, returns to normal
operation, ignoring the set time in A055.
(Example 5-b), (Example 6-b)
