Example 1 for encoder matching:
Axis with rotary encoder (500 pulses) mounted directly on the motor. The internal multiplica-
tion factor is 4. The internal computational resolution amounts to 1,000 increments per de-
gree.

One encoder increment corresponds to 180 internal increments. One encoder increment cor-
responds 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 sta-
ges exist:
Gear stage 1: Motor/spindle = 2.5/1
Gear stage 2: Motor/spindle = 1/1
