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. The drive will not start
if a Run command is input before the time t (C1-02) has expired. Cycle the Run command that was activated during time t
after t has expired to start the drive.
The wait time t is determined by the output frequency when the Run command is removed and by the active deceleration time.
n b2-01: DC Injection Braking Start Frequency
Active when "Ramp to Stop" is selected as the stopping method (b1-03 = 0).
No.
b2-01
The function triggered by parameter b2-01 depends on the control mode that has been selected.
V/f, V/f w/PG, and OLV (A1-02 = 0, 1, 2)
For these control modes, parameter b2-01 sets the starting frequency for DC Injection Braking at Stop. When the output
frequency falls below the setting of b2-01, DC Injection Braking is enabled for the time set in parameter b2-04.
