External DC Injection Braking (A051 = 00)
•Allocate 07 (DB) to the desired multi-function input. DC injection braking can be applied by turning
on/off the DB terminal, regardless of the DC injection braking selection (A051).
•Set the DC injection braking power in A054.
•If the DC injection braking delay time (A053) is set, the Inverter output will be shut off during the
specified time period and the motor goes into free-run status. After the set time elapses, DC
injection braking starts.
•Set the DC injection braking time (A055) or the DB setting while taking into account motor heat
generation. Long continuous use of DB may cause the motor to burn out.
•Perform each setting according to your system after selecting the level or edge operation in A056
