Functions
DC Injection Braking Carrier Frequency
This function can be set using DC Injection Braking Carrier Frequency (A059). Note that setting
a 5 kHz or higher frequency automatically reduces the braking power.
Refer to the DC injection braking power limiter shown below.
External DC Injection Braking
Allocate "07: DB (External DC injection braking)" to any Multi-function Input Selections (C001
to C007).
DC injection braking is applied when the DB terminal is turned ON/OFF, regardless of Internal
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 the 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 selecting the setting of DC Injection
Braking Edge/Level Selection (A056).
