 Inverter overload prevention function is activated when the current is above inverter rated current.
 Multi-function output terminal (MO) or Multi-function relay (3ABC) is used as the alarm signal output
during inverter overload trip.


Select the Drive mode when frequency reference set via Analog (V1, I) input terminal or
communication option is lost.
 I16: This is to set the criteria for analog input signal loss.

When half the value set in I2, I7, I12 is
entered

When less than the value set in I2, I7, I12 is
entered
Ex 1) The inverter determines the freq reference is lost when DRV- Frq is set to 3 (Analog
V1 input), I16 to 1 and analog input signal is less than half the value set in I7.
Ex 2) The inverter determines the freq reference is lost when DRV- Frq is set to 6 (V1+I),
I16 to 2 and V1 input signal is either below the value set in I7 or I input value is less than
the I12 value.
