SERVOPACK Overload Protection Characteristics
The overload detection level is set for hot start conditions with a SERVOPACK
surrounding air temperature 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 Servomotor that has the lower overload protection character-
istics.
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 per-
form continuous duty operation with an output of 100% or higher.
For a Yaskawa-specified combination of SERVOPACK and Servomotor,
maintain the effective torque or the effective force within the continuous
duty zone of the torque-motor speed characteristics or the force-motor
speed characteristics of the Servomotor. Refer to the following catalog for
the torque-motor speed characteristics and force-motor speed characteris-
tics.
