Overspeed detection level
Address:
0xF943
Min.:
0
Unit:
%
Max.: 50 Data type: UInt16
Default:
5
Change: In real time
Value Range:
0.0% to 50.0%
Description
During overspeed protection, when the detected motor speed exceeds F0‑10
(Maximum frequency) for a percentage higher than F9‑67 (Overspeed detection
level) and for longer than the time set by F9‑68 (Overspeed detection time), the AC
drive reports a motor overspeed fault (Err43) and acts as selected by F9‑50 (Fault
protection action selection 4).
When F9‑68 (Overspeed detection time) is set to 0.0s, the overspeed detection
function is disabled.
The overspeed protection is valid only in the FVC mode (F0‑01 = 1).
