Chapter 7 Detailed Explanations of Functional Parameters
P419
Flank restart time Default value 5
Range
0-10
Unit
When inverter enabled the flying restart function, inverter tracing
motor speed downwards within the setting time. If it is not completed
within setting time, inverter protects.
In above example, when t value > P419 setting value, inverter
protects.
P420
Fault restart times Default value 0
Range
0-5
Unit
1
P421
Delay time for restart after fault Default value 2
Range
0-100
Unit
1
After alarm (such as current, over-voltage and so on) occurs,
inverter resets automatically (valid when non-zero as set by P420),
after the period of time set by P421, inverter starts up according to
setting start-up means (P200).
After start-up, if no alarm happens within 60 seconds, inverter resets
P420 automatically, after start-up,
If alarm happens again within 60 seconds, inverter records number
of alarms, and when number of alarms reaches set value of P420,
inverter stops output.
Attention: If P420=0, fault restart is invalid.
