FHA-32C-100-E250-C HarmonicDrive Flat Hollow-Shaft AC Servo ActuatorFHA-C Series
The one-way positioning accuracy is defined as the maximum positional difference between the commanded position and the actual stop position when a series of positioning moves are performed in the same rotation direction. (Refer to JIS B-6201-1987).
The FHA-C mini actuator incorporates a Harmonic Drive® gear which inherently has high rotational position accuracy.
Because of the gearing’s high ratio, any rotational error at the input (i.e. motor shaft position error or motor feedback error) is reduced by a factor of the ratio (1/ratio) and typically becomes negligible at the output. Therefore most of the error is represented by the transmission error of the Harmonic Drive gear itself.
