Detector resolution
The motors of the FHA-C mini series actuators are equipped with an incremental encoder of 2,000
pulses per revolution, and an absolute encoder of 131,072 pulses per revolution. The function reduces
the motor output to 1/30, 1/50 and 1/100 by using a speed reducer HarmonicDrive
®
for precision
control. The resolution per revolution is 30, 50 or 100 times. Additionally, the incremental encoder
signal has a x4 electrical interpolation.
The high resolutions obtained from the information above are summarized in the table below.
