Select the Drive mode when frequency reference set via V1 and I or (V1+I) input terminal or communication
option is lost.
I16 : This is to set the criteria for analog input signal loss when frequency reference is given by V1, I,
V1+I or Communication option.
I16
EX 1) The inverter determines that the freq reference is lost when DRV- Frq is set to 3 (Analog V1 input), I 16
to 1 and analog input signal is less than half of the minimum value set in I 7.
EX 2) The inverter determines that the freq reference is lost when DRV- Frq is set to 6 (V1+I), I 16 to 2 and V1
input signal is either below the minimum value set in I 7 or I input value is less than the I 12 value.
I62 : When no frequency command is given for the time set in I63, set the drive mode as the table below.
