: DC braking
When input is active, DC-Injection braking is enabled during starting and stopping of the AC Drive.
DC Injection braking is disabled when a run or jog command is active. Refer to the DC braking time diagram below.

: Motor 2 Selection
Motor 1 or motor 2 can be selected via the digital input. This function is only available in V/F control mode.
03-0X =47
: Fire mode
Fire Mode must first be enabled with parameter 08-48. When input is active disables all AC Drive warning and
hardware protections. This function is commonly used in commercial applications where the AC Drive controls an
exhaust fan and needs run to destruction in case of a fire.
03-0X =48
: KEB acceleration
When input is active enables KEB (Kinetic Energy Braking) to accelerate back to the preset frequency after braking.
Refer to the parameter description of 11-47 and 11-48 for more details on KEB.
Note:
Parameter 11-47 to a value greater than 0 before setting 03-0X=48.
03-0X =65
: Short Circuit braking
When active stops AC Drive by turning on Short-circuit braking. Short-circuit braking is disabled when a run or jog
command is active.
