Example 2 for encoder matching:
Spindle with rotary encoder mounted on the motor (2,048 pulses), internal multiplication = 4,
2 gear stages existing:
Gear stage 1: Motor/spindle = 2.5/1
Gear stage 2: Motor/spindle = 1/1

Spindle setpoint adaptation
To adapt the spindle setpoint and its gear stage, the following axis MD and interface signals
are relevant:
Number Description
32010 Rapid traverse in jog mode
32020 Jog axis velocity
35110 Maximum speed for gear change (gear stage no.): 0..5
35120 Minimum speed for gear change (gear stage no.): 0..5
35130 Maximum speed of gear stage (gear stage no.): 0...5
35140 Minimum speed of gearsetp (gear stage no.): 0...5
35200 Acceleration in speed control mode [gear stage no.]: 0...5
31060 Numerator load gearbox (control parameter set no.): 0...5
31050 Denominator load gearbox (control parameter no.): 0...5
