This parameter can be adjusted
based on site requirements. If
Output freq. track rate (Hz/s)
is slow, the inverter frequency is
different from the bypass
frequency when the bypass
frequency changes. If output is
overloaded or the inverter is
faulty, an interruption (less than
20 ms) occurs when the UPS
transfers from normal mode to
bypass mode. If
Output freq.

is fast, the
