Example 1 for encoder matching:
Spindle with rotary encoder (500 pulses) mounted directly on the motor. The
internal multiplication factor is 4. The internal computational resolution
amounts to 1,000 increments per degree.
360 degrees MD 31080
Internal resolution = ------------------------- x ----------------------- x 1000
MD 31020 x 4 MD 31070
360 x 1 x 1000
Internal resolution = ---------------------------- = 180
500 x 4 x 1
One encoder increment corresponds to 180 internal increments. One encoder
increment corresponds to 0.18 degrees (minimum positioning step).
Example 2 for encoder matching:
Spindle with rotary encoder on motor (2,048 pulses), internal multiplication
= 4, 2 speed stages exist:
Gear stage 1: Motor/spindle = 2.5/1
Gear stage 2: Motor/spindle = 1/1
Gear stage 1

Internal resolution = ----------------- x ------------- x ------------ x 1000pulses/deg = 17.5781
4 x 2048 1 2.5
One encoder increment corresponds to 17.5781 internal increments. One
encoder increment corresponds to 0.0175781 degrees (minimum positioning
step).
