How does the ATV630 Process drives stall function work?
Issue:
How to set up stall function on the ATV630 Process drive?
Product Line:
Altivar 630
Environment:
All serial numbers
Cause:
Stall function
Resolution:
This function helps to prevent a motor overload by monitoring the motor current and the speed rise time.
A stalling condition is when:
An output frequency is smaller than the stalling frequency [Stall Frequency] StP3
And an output current is higher than the stalling current [Stall Current] StP2
During a time longer than the stalling time [Stall Max Time] StP1
That means that you must meet three conditions, then a stalling condition occurs, an [Motor Stall Error] StF error is triggered.
For example,
Set StP3=10HZ, StP2=100% (meaning rated motor current)
StP1=5s
When the drive is running at 9.9HZ, motor current is above rated motor current, then after 5S, an [Motor Stall Error] StF error is triggered.
If the drive is running at 10.1HZ, an StF error is not triggered.
