10.1 Overload protection characteristics
An electronic thermal is built in the servo amplifier to protect the servo motor, servo amplifier and servo
motor power wires from overloads.
[AL. 50 Overload 1] occurs if overload operation performed is above the electronic thermal protection curve
shown in fig. 10.1. [AL. 51 Overload 2] occurs if the maximum current is applied continuously for several
seconds due to machine collision, etc. Use the equipment on the left-side area of the continuous or broken
line in the graph.
For the system where the unbalanced torque occurs, such as a vertical axis system, it is recommended that
the unbalanced torque of the machine be kept at 70% or less of the motor's rated torque.
This servo amplifier has servo motor overload protective function. (The servo motor overload current (full
load current) is set on the basis of 120% rated current of the servo amplifier.)
