SERVOPACK Overload Protection Characteristics (400 V Models)
The overload detection level is set for hot start conditions with a SERVOPACK surrounding air tempera-
ture of 55°C.
An overload alarm (A.710 or A.720) will occur if overload operation that exceeds the overload protection
characteristics shown in the following diagram (i.e., operation on the right side of the applicable line) is
performed.
The actual overload detection level will be the detection level of the connected SERVOPACK or Servo
Motor that has the lower overload protection characteristics.
In most cases, that will be the overload protection characteristics of the Servo Motor.
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 Servo Motor, maintain the effective torque (or effective
force) within the continuous duty zone of the torque-motor speed characteristic (or force-motor speed characteris-
tics) of the Servo Motor.
