►
I16: This is to set the criteria for analog input signal loss.
I16
[Criteria for analog input
signal loss]
0
Disabled (Does not check the analog
input signal loss)
1
When half the value set in I2, I7, I12 is
entered
2
When less than the value set in I 2, I 7,
I 12 is entered
Ex 1) The inverter determines the freq reference is lost when DRV-Frq is set to 3 (Analog
V1 input), I 16 to 1 and analog input signalis less than half the value set in I 7.
Ex 2) The inverter determines 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 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.
I62
[Drive mode select after
loss of frequency
command]
0
Continuous operation with the frequency
before command loss occurs
1 Free run stop (output cut off)
2 Decel to stop
3 Lost Preset
►
I54, I55: Multi-function output terminal Relay1 or Multi-function relay output Relay2 is
used to output information on loss of frequency command to external sequence
Ex) when I16 is set to 2, I62 to 2, I63 to 5.0 sec and I54 to 11, respectively,
