Parameter Descriptions

4.7 Parameter Group 6: Analog In/Out

4.7.1 6-** Analog In/Out
Parameter group for configuring analog inputs and
outputs.
4.7.2 6-0* Analog I/O Mode
4 4
Parameter group for setting up the analog I/O configu-
ration.
6-00 Live Zero Timeout Time

4.7.3 6-1* Analog Input 1
Parameters for configuring scaling and limits for analog
input 1 (terminal 53).

VLT
Function:
The Live Zero function is used for monitoring
the signal on an analog input. If the signal
disappears, a Live Zero warning is reported.
is applied (6-01 Live Zero Timeout Time).
If the signal reappears during the set delay,
timer will be reset.
When live zero is detected, the frequency
converter freezes output frequency and starts
Live Zero Timeout timer.
Function:
Function is activated if input signal is below
50% of value set in 6-10 Terminal 53 Low
Voltage, 6-12 Terminal 53 Low Current or 6-22
Terminal 60 Low Current.
Function is disabled.
Output frequency remains at value it had
when live zero was detected.
Frequency converter ramps down to 0 Hz.
Remove live zero error condition before
restarting frequency converter.
Frequency converter ramps to jog speed, see
3-11 Jog Speed.
Frequency converter ramps to Motor Speed
High Limit, see 4-14 Motor Speed High Limit.
Frequency converter ramps down to 0 Hz
and then trips. Remove live zero condition
and activate reset before restarting the
frequency converter.
