îš„Inputting the DC Injection Brake Command from Control Circuit Terminals
If you set a digital input terminal (H1-) to 60 (DC injection brake command), the DC brake can be applied
by enabling or disabling this input. 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 (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, and if a run command
or jog command is input, the DC injection brake will be disabled, and operation will resume.
