4.12

Overload protection (electronic thermal) function

An electronic thermal is built in the servo amplifier to protect the servo motor, servo amplifier and servo motor power wires
from overloads.
[AL. 050 Overload 1] occurs if overload operation performed is above the electronic thermal protection curve. [AL. 051
Overload 2] occurs if the maximum current is applied continuously for several seconds due to a machine collision, etc.

Precautions

• After [AL. 050 Overload 1] or [AL. 051 Overload 2] occurs, allow about 30 minutes of cooling time.
