Encoder resolution
The motors of the FHA-C mini series actuators are equipped with an incremental encoder of 2,000
pulses per revolution. The motor output speed is reduced to 1/30, 1/50 or 1/100 using the speed
reducer HarmonicDrive
®
for precision control. Accordingly, the resolution per a single revolution is 30,
50 or 100 times. In addition, the resolution is electrically multiplied by 4 when an actuator is combined
with a dedicated servo amplifier.
The resolution of the output shaft at each reduction ratio is shown in the table below.
