Activating DC braking manually

By means of the "Activate DC braking" function, DC braking can be activated manually.

Preconditions

The current for DC braking must be set > 0 % so that the function can be executed.

Parameter

Address	Name / setting range / [default setting]		Information
0x2631:005 (P400.05)	Function list: Activate DC braking (Function list: DC braking) – Further possible settings: Trigger list		Assignment of a trigger for the "Activate DC braking" function. Trigger = TRUE: Activate DC braking. Trigger = FALSE: Deactivate DC braking. CAUTION! DC braking remains active as long as the trigger is set to TRUE. DC braking
0x2631:005 (P400.05)	0	Not connected	No trigger assigned (trigger is constantly FALSE).

Example for operating mode

–

Switch S1 starts the motor in forward direction of rotation. De-asserting switch S1 stops the motor again.

–

Switch S2 activates DC braking.

Parameter	Designation	Setting for this example
0x2631:001 (P400.01)	Enable inverter	Constant TRUE [1]
0x2631:002 (P400.02)	Run	Digital input 1 [11]
0x2631:004 (P400.04)	Reset fault	Not connected [0]
0x2631:005 (P400.05)	Activate DC braking	Digital input 2 [12]
0x2824 (P200.00)	Control selection	Flexible I/O configuration [0]
0x2838:003 (P203.03)	Stop method	Standard ramp [1]
0x2860:001 (P201.01)	Frequency control: Default setpoint source	Analog input 1 [2]
0x2B84:001 (P704.01)	DC braking: Current	10 %


The status signals can be assigned to digital outputs. Configure digital outputs

①	If DC braking is activated while the motor is running, the output pulses of the inverter are disabled immediately. For stopping the motor, the current set in 0x2B84:001 (P704.01) is injected. The exact drive behaviour depends on the settings for the "DC braking" function and the load properties.
