In the voltage sag and interruption of up to 2s, runaway of the microcomputer circuit after power failure, rather than unsafe behavior, is no problem to continue normal operation.
interruptions of up to 2 s and Shun low in the decryption den after the runaway for microcomputer circuit, unsafe behavior without, continues to run a successful and without problems.
In 瞬断 and 瞬低 until 2s, reckless driving, the non-safe operation of the microcomputer circuit don't have a return train afterward, and I continue normal movement, and there is no problem.
