Servopack Overload Protection Characteristics - YASKAWA SGD7S Product Manual

2.1.2

SERVOPACK Overload Protection Characteristics

The overload detection level is set for hot start conditions with a SERVOPACK surrounding air tem-
perature of 55°C.
An overload alarm (A.710 or A.720) will occur if overload operation that exceeds the overload pro-
tection characteristics shown in the following diagram (i.e., operation on the right side of the appli-
cable line) is performed.
The actual overload detection level will be the detection level of the connected SERVOPACK or Ser-
vomotor that has the lower overload protection characteristics.
In most cases, that will be the overload protection characteristics of the Servomotor.

Note: The above overload protection characteristics do not mean that you can perform continuous duty operation
with an output of 100% or higher.
For a Yaskawa-specified combination of SERVOPACK and Servomotor, maintain the effective torque within
the continuous duty zone of the torque-motor speed characteristic of the Servomotor.
