Internal DC Injection Braking (Operates Only at the Set Frequency) (A051: 02)
• DC injection braking can be applied when the output frequency becomes lower than the DC
injection braking frequency (A052).
• Neither (2) external nor (3) internal DC injection braking is available while this function is selected.
• Operates only when the RUN command is turned on.
• DC injection braking starts when both the reference and current frequencies become lower than
A052. (Example 7-a)
• When the reference frequency exceeds the A052 set value by 2 Hz or more, DC injection braking
is released and the output returns to normal. (Example 7-a)
• If the reference frequency is "0" when the operation starts with analog input, the initial operation is
DC injection braking because both the reference and current frequencies are "0". (Example 7-b)
