FSP Amplifier Short Form Installation Guide Overload Characteristics
10. Overload Characteristics
The FSP Amplifier has a built-in overload protective function that protects the
amplifier-motor pair from overload. Allowable power for the FSP Amplifier is
limited by the overload protective function as shown in the figure below.
The overload detection level is set under hot start* conditions at a servomotor
ambient temperature of 40ºC (104ºF).
* A hot start indicates that both the FSP Amplifier and servomotor have run long
enough at the rated load to be thermally saturated.
Note: The overload protection characteristics of A and B in the figure are applicable
when the FSP Amplifier is combined with one of the following Yaskawa
servomotors:
A: SGMAH or SGMPH servomotor with capacity of maximum 400W.
B: SGMAH or SGMPH servomotors with a capacity more than 400W and SGMGH,
SGMSH, SGMDH and SGMUH servomotors.
