Device Functions
Typical applications for breakaway pulse
6-8
Typical applications for breakaway pulses are load machines with inverse torque
behavior, e.g. crushers and mills.
Note
A breakaway pulse that is too high may lead to the error message "Current
measurement range exceeded".
Remedy: Use larger starter dimensions or a lower breakaway voltage.
Only set the breakaway pulse when it is reallly required (e.g. for mills for
crushers).
A wrongly set breakaway pulse, e.g. for pumps, may lead to the error message
"Incorrect start conditions".
