10. CHARACTERISTICS
10.1 Overload protection characteristics
An electronic thermal relay is built in the servo amplifier to protect the servo motor and servo amplifier from
overloads. Overload 1 alarm (50) occurs if overload operation performed is above the electronic thermal relay
protection curve shown in any of Figs 10.1. Overload 2 alarm (51) occurs if the maximum current flew
continuously for several seconds due to machine collision, etc. Use the equipment on the left-hand side area of
the continuous or broken line in the graph.
In a machine like the one for vertical lift application where unbalanced torque will be produced, it is
recommended to use the machine so that the unbalanced torque is 70% or less of the rated torque.
When you carry out adhesion mounting of the servo amplifier, make circumference temperature into 0 to 45
,
or use it at 75% or smaller effective load ratio.
