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 p ower for the FSP Amp lifier 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 p rotection characteristics of A and B in the figure are ap p licable

when the FSP Amplifier is combined with one of the following Yaskawa

servomotors:

A: SGMAH or SGM PH servomotor with capacity of maximum 400W.

B: SGMAH or SGMPH servomotors with a capacity more than 400W and SGM GH,

SGMSH, SGMDH and SGMUH servomotors.
