3.8 Parameters: 6-** Main Menu - AnalogIn/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:• Terminals 53.• Terminals 54.The analog inputs can be allocated freely to either voltage(0–10 V) or current input (0/4–20 mA).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 timeout in s. Livezero timeout time is active foranalog inputs, that is terminal 53 orterminal 54, used as reference orfeedback sources.If the reference signal valueassociated with the selected currentinput drops below 50% of the valueset in:• Parameter 6-10 Terminal 53Low Voltage• Parameter 6-12 Terminal 53Low Current• Parameter 6-20 Terminal 54Low Voltage• Parameter 6-22 Terminal 54Low Currentfor a time period longer than thetime set in parameter 6-00 Live ZeroTimeout Time, the function selectedin parameter 6-01 Live Zero TimeoutFunction is activated.6-01 Live Zero Timeout FunctionOption: Function:Select the timeout function. Aminimum of 1 V or 2 mA isrequired to trigger the Live Zero.The function set inparameter 6-01 Live Zero TimeoutFunction is activated if the inputsignal on terminal 53 or 54 is below50% of the value in:6-01 Live Zero Timeout FunctionOption: Function:• Parameter 6-10 Terminal 53Low Voltage.• Parameter 6-12 Terminal 53Low Current.• Parameter 6-20 Terminal 54Low Voltage.• Parameter 6-22 Terminal 54Low Current.The function can also be activatedfor a time period defined inparameter 6-00 Live Zero TimeoutTime. If several timeouts occursimultaneously, the frequencyconverter prioritizes the timeoutfunctions as follows:1. Parameter 6-01 Live ZeroTimeout Function.2. Parameter 8-04 ControlTimeout Function.[0] * Off[1] Freeze output Frozen at the present value.
