Description
Def.
AIN Fault [790]
This parameter turns on / off testing of the analog input faults. The fault is
evaluated only if the input is set to 4-20mA or 2-10V, output value is under the
minimal value and the fault testing is turned on.
Is
evaluated
Is evaluated
If the analog input is for a long time under the minimal value, the inverter generates the
fault.
Is not evaluated Inverter accepts any analog input value.
External fault
source [264]
Setting the source of the external fault. If the source is active, the fault " E7-
External fault (page 32)" is generated. Is used as an emergency stop. Fault
blocks the inverter operation.

After rise of AC voltage [221] (page 19) above this value for the time given by Time V
AC [771] (page 74), inverter generates a fault E35-Grid overvoltage (page 33).
