nInputting the DC Injection Brake Command from Control Circuit Terminals
If a multi-function input terminal (H1-oo) is set to 60 (DC injection brake command), the DC injection
brake is applied to the motor by turning ON the terminal (the DC injection brake command) when the Inverter
is being stopped.
The time chart for the DC injection brake is shown below.
