8-4 Overload Characteristics
Overload Characteristics Graphs
(Electronic Thermal Function)
An overload protection (electronic thermal) function is built into the Servo Drive to protect the Servo
Drive and Servomotor from overloading.
If an overload does occur, first eliminate the cause of the error and then wait at least one minute for
the Servomotor temperature to drop before turning ON the power again.
If the power is turned ON again repeatedly at short intervals, the Servomotor windings may burn out.
The following graphs show the characteristics of the load rate and electronic thermal function’s
operation time.
When the torque command = 0, and a constant torque command is continuously applied after three
or more times the overload time constant has elapsed, the overload time t [s] will be:
t [s] = − Overload time constant [s]
(The overload time constant [s] depends on the Servomotor. The standard overload level is 115%.)
