3-2 Overload Characteristics
(Electronic Thermal Function)
An overload protection function (electronic thermal) is built into the Servo Drive to protect the Servo
Drive and Servomotor from overloading.
If an overload occurs, first eliminate the cause of the overload and then wait at least 1 minute for the
motor temperature to drop before turning ON the power again.
If the alarm reset operation is repeated at short intervals, the motor windings may burn out.
The following characteristics graphs show the relationship between the load ratio and electronic thermal
function’s operation time.
