3.8 Parameters: 6-** Analog In/Out3.8.1 6-0* Analog I/O ModeThe analog inputs can freely be allocated to be eithervoltage (FC 301: 0..10 V, FC 302: 0..± 10 V) or current (FC301/FC 302: 0/4..20 mA) input.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 time period. Live zerotimeout time is active for analog inputs, that is,terminal 53 or terminal 54, used as reference orfeedback sources. If the reference signal valueassociated with the selected current input dropsbelow 50% of the value set in 6-10 Terminal 53Low Voltage, 6-12 Terminal 53 Low Current,6-20 Terminal 54 Low Voltage or 6-22 Terminal 54Low Current for a time period longer than thetime set in parameter 6-00 Live Zero Timeout Time,the function selected in 6-01 Live Zero TimeoutFunction is activated.6-01 Live Zero Timeout FunctionOption: Function:Select the timeout function. The function setin parameter 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 timeouts occursimultaneously, the frequency converterprioritises the timeout functions as follows:1. Parameter 6-01 Live Zero TimeoutFunction.2.
