Overload Characteristics
Servo amplifiers have a built-in overload protection function that protects
the servo amplifiers and servo motors from overload. Allowable power for
the servo amplifiers 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 40°C.
Note: The overload protection characteristics of A and B in the figure are applicable when the servo amplifier is
combined with one of the following servomotors:
A: SGMAH or SGMPH servomotor with a maximum capacity of 400 W, 100 V and 200 V only.
B: Other servomotors similar to the SGMAH, SGMPH, SGMGH, SGMSH, and SGMUH.
