Example: Automatic DC braking when starting the motor
In order that the DC braking is automatically active when the motor is started, the start method "DC braking [1]" must be set in 0x2838:001 (P203.01).
–
The DC braking is carried out with the braking current set in 0x2B84:001 (P704.01).
–
Only after the hold time 0x2B84:002 (P704.02) has elapsed, the motor is accelerated to the setpoint.

①
|
After the start command, the DC braking is active. Only after the hold time 0x2B84:002 (P704.02) has elapsed, the motor is accelerated to the setpoint.
|
|
②
|
The motor is stopped with the stop method set in 0x2838:003 (P203.03). In the example: Stop with standard ramp.
|
|
③
|
If the inverter is disabled, the motor coasts.
