(2) External DC braking
Assign function "07" (DB) to terminal function (C001 to C008).
Turn the DB terminal on and off to control the direct braking, regardless of the setting of DC braking enable (A051).
Adjust the braking force by adjusting the DC braking force setting (A054).
When you set the DC braking wait time (A053), the inverter output will be shut off for the set period of delay, and the
motor will run freely during the period. DC braking will be restarted after the delay.
When setting the DC braking time with function "A055" or for the DC braking operation via the DB terminal, determine
the length of time in consideration of the heat generation on the motor.
Select the braking mode by the DC braking/edge or level detection for [DB] input (A056), and then make any other
necessary settings suitable for your system.
(a) Edge mode (A056: 00)
(b) Level mode (A056: 01)
