available output. Power reduction
att empts to avoid overheat ing and
automatic shut-down of the system.
Possible action
Reduce t he load to att ain optimum
c utting speed.
Reduce the load or increase motor and
power unit cooling.
Reduce the load or increase motor and
power unit cooling.
Mot or cooling c an be improved by
in creasing t he amount of coolant or
