îš„Inputting the DC Injection Brake Command from Control Circuit Terminals
If you set a multi-function contact input terminal (H1-) to 60 (DC injection brake command), you can
apply the DC injection brake to the motor by turning ON the terminal for which the DC injection brake com-
mand has been set when the Inverter is being stopped.
The time chart for the DC injection brake is shown below.

îš„Changing the DC Injection Brake Current Using an Analog Input
If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection)
to 6 (DC injection brake current), you can change the DC
injection brake current level using the analog input.
At 10 V input (voltage) or 20 mA input (current), 100% of the Inverter rated current will be applied.

If you input the DC injection brake command from an external terminal, or if the Run Com-
mand and jog command are input, the DC injection brake will be disabled, and operation will
resume.
