Figure 1.7
Figure 1.7 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 1.8
Figure 1.8 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.
