DC Injection Braking Carrier Frequency
You can set a DC injection braking carrier frequency in A059. Note that setting a 5 kHz or higher
frequency automatically reduces the braking power. Refer to the following figure (DC injection
braking power limit).
External DC Injection Braking
• Allocate 07 (DB) to any of multi-function inputs C001 to C008.
• DC injection braking can be applied by turning on/off the DB terminal, regardless of DC injection
braking selection A051.
• Set a braking power level in DC injection braking power A054.
• If DC injection braking delay time A053 is set, the Inverter output is shut off during the set time
period and the motor goes into free-run status. After the set time elapses, DC injection braking
starts.
• Set DC injection braking time A055 via the Digital Operator or the DB terminal while taking into
account motor heat generation.
• Perform each setting according to your system after setting DC injection braking method selection
A056.
