Overload Characteristics
The overload detection level is set under hot start
*
conditions at a servomotor surrounding air temperature of
40
°
C.
∗
A hot start indicates that both the SERVOPACK and the servomotor have run long enough at the rated load to be ther-
mally saturated.
Note: Overload characteristics shown above do not guarantee continuous duty of 100% or more output. Use a servomotor
with effective torque within the continuous duty zone in
3.2.2 Torque-Motor Speed Characteristics
.
3.2.4
Holding Brake Electrical Specifications
The holding brake electrical specifications are shown below. The holding brake is only used to hold the load
and cannot be used to stop the servomotor.
Note 1. For information on the holding brake power supply and connecting methods, refer to
8.4.3 (1) Wiring Example
.
2. The holding brake open time and holding brake operation time vary depending on which discharge circuit is
used. Make sure holding brake open time and holding brake operation time are correct for your servomotor.
