Functions
Internal DC Injection Braking (A051: 01)
• DC injection braking is applied without terminal operation at start/stop of the Inverter.
To use internal DC injection braking, set DC injection braking selection A051 to 01.
• Set the startup DC injection braking power in A057. In A058, set the startup DC injection braking
time, regardless of the edge or level operation. (Example 4-a), (Example 4-b)
• Set DC injection braking power A054 to define the braking power other than at startup.
• Set the DC injection braking starting frequency in DC injection braking frequency A052.
• Once DC injection braking delay time A053 is set, the Inverter stops output when the frequency
reaches the A052 value after the RUN command (FW) has been turned off. During the set time in
A053, the motor remains in free-run status. After the set time in A053, DC injection braking starts.
• Edge and Level operations for internal DC injection braking work differently when the RUN
command switches from STOP to RUN.
Edge operation: Giving priority to DC injection braking time A055, performs DC injection braking for
the set time in A055. DC injection braking operates 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 DC injec-
tion braking time A055. When the RUN command is turned on during DC injection
braking, returns to normal operation, ignoring the set time in A055. (Example 5-b),
