Setting 2: DC Injection Braking to stop
When the Run command is removed, the drive will enter baseblock (turn off its output) for the minimum baseblock time
(L2-03). Once the minimum baseblock time has expired, the drive will brake the motor by injecting DC current into the
motor windings. The stopping time is significantly faster than when compared with simply coasting to stop. The level of
current used for DC Injection Braking is set by parameter b2-02 (default = 50%).
Note: This function is not available in the control modes for PM motors (A1-02 = 5).
Figure 5.4
Figure 5.4 DC Injection Braking to Stop
The time for DC Injection Braking is determined by the value set to b2-04 and by the output frequency at the time the
Run command is removed. It can be calculated by:
Figure 5.5
Figure 5.5 DC Injection Braking Time Depending on Output Frequency
Note: If an overcurrent (oC) fault occurs during DC Injection Braking to stop, lengthen the minimum baseblock time (L2-03) until the
fault no longer occurs.
Setting 3: Coast to Stop with Timer
When the Run command is removed, the drive will turn off its output and the motor will coast to stop. If a Run command
is input before the time t (value of C1-02) has expired, the drive will not start. A Run command activated during time t
must be cycled after t has expired in order to start the drive.
