3.8 Parameters 6-** Analog In/Out3.8.1 6-0* Analog I/O ModeParameter group for setting up the analog I/O configu-ration.The frequency converter is equipped with 2 analog inputs:Terminal 53 and 54. The analog inputs can freely beallocated to either voltage (0-10 V) or current input (0/4-20mA)NOTICEThermistors may be connected to either an analog or adigital input.6-00 Live Zero Timeout TimeRange: Function:10 s* [1 -99 s]Enter the Live Zero Time-out time period. LiveZero Time-out Time is active for analog inputs, i.e.terminal 53 or terminal 54, used as reference orfeedback sources. If the reference signal valueassociated with the selected current input fallsbelow 50% of the value set inparameter 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 a timeperiod longer than the time set inparameter 6-00 Live Zero Timeout Time, the functionselected in parameter 6-01 Live Zero TimeoutFunction is activated.6-01 Live Zero Timeout FunctionOption: Function:Select the time-out function. The function set inparameter 6-01 Live Zero Timeout Function isactivated if the input signal on terminal 53 or54 is below 50% of the value inparameter 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 Live ZeroTimeout Time. If several time-outs occur simulta-neously, the frequency converter prioritises thetime-out functions as follows1. Parameter 6-01 Live Zero TimeoutFunction2.
