Encoder specifications
The encoder specifications are shown as follows:
Output pulses per revolution
20-bit + 12-bit multi-turn
With the function of electronic gear, you can define the motor revolutions according to the
number of setpoint pulses, and sequentially define the distance of mechanical movement.
The minimum traveling distance of load shaft according to one setpoint pulse is called a
length unit (LU); for example, one pulse results in 1 µm movement.
