6-01 Live Zero Timeout FunctionOption: Function:Select the Timeout function. The function setin parameter 6-01 Live Zero Timeout Functionwill be activated if the input signal onterminal 53 or 54 is below 50% of the valuein parameter 6-10 Terminal 53 Low Voltage,parameter 6-12 Terminal 53 Low Current,parameter 6-20 Terminal 54 Low Voltage orparameter 6-22 Terminal 54 Low Current for atime period defined in parameter 6-00 LiveZero Timeout Time. If several timeouts occursimultaneously, the adjustable frequency driveprioritizes the timeout functions as follows1. Parameter 6-01 Live Zero TimeoutFunction2.
