7 Other Functions
• DC injection braking works according to the ON/OFF status of the terminal DB, regardless of whether
the DC Injection Braking Selection (A051) is set to 00 (Disabled) or 01 (Enabled). Note that the DC
injection braking via the terminal DB has priority over the DC injection braking via the parameter set-
ting 01 (Enabled).
However, when A051 is set to 02, DC injection braking via the terminal DB is disabled.
• In the DC Injection Braking Power (A054), set the braking power required for your application.
A limit value is automatically applied to the Carrier Frequency (b083) setting according to the DC Injec-
tion Braking Power (A054) setting.
• 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).
(a) Edge operation (A056 = 00)
(Example 1-a)
*1. Set the DC Injection Braking Time (A055) or the DC injection time by DB input in consideration of the heat
generation of the motor.
(a) Edge operation (A056 = 00)
(Example 2-a)
7 - 96
(b) Level operation (A056 = 01)
(Example 1-b)
(b) Level operation (A056 = 01)
(Example 2-b)
