Motor/Encoder Gearbox Ratio - Lenze i950 Commissioning Manual

6.1.4

Motor/encoder gearbox ratio

The necessary data for configuring the gearbox ratio is listed in the gearbox cat-
alog.
For a precise specification of the gearbox ratio, the specified number of teeth
z1 ... z4 from the gearbox catalog must be used.
The gearbox ratio indicates how many motor axis revolutions equal one revolution of the load
axis.
The gearbox ratio is configured using a quotient (numerator/denominator).
The gearbox ratio for the motor is influenced by 4 parameters:
• Gearbox factor numerator
Gearbox factor denominator
•
Additional gearbox factor numerator
•
• Additional gearbox factor denominator
The gearbox ratio for the second encoder is influenced by 2 parameters:
Gearbox factor numerator
•
• Gearbox factor denominator
Example:
After 58,667 rotations (i) of the motor axis, the spindle turns once.
