Note: Before starting an uncontrolled rotating motor (e.g., a fan motor driven by windmill effect), use DC Injection to stop the motor before
starting it. Otherwise motor stalling and other faults can occur.
n b2-04: DC Injection Braking Time at Stop
When the output frequency falls below the minimum output frequency setting E1-09, the drive applies DC injection for the
time set in b2-04. Used to completely stop a motor with high inertia load after ramp down. Increase the setting if the motor
