• When the DC Injection Braking Delay Time (A053) is set, the inverter shuts off its output and remains
in a free-run sate during the set time. After the expiration of the set time, the inverter starts DC injec-
tion braking.
• In the DC Injection Braking Edge/Level Selection (A056), you can set the operation of DC injection
braking after the terminal DB turns ON.
Select optimal operation according to your system, with reference to the example below.
• When A056 is set to 00 (Edge operation), you need to also set the time during which DC injection
braking is applied in the DC Injection Braking Time (A055).
