6.1.4 Motor/encoder gearbox rao
The necessary data for conguring the gearbox
rao is listed in the gearbox cat-
alog.
For a precise
specicaon of the gearbox rao, the specied number of teeth
z1 ... z4 from the gearbox catalog must be used.
The gearbox
rao indicates how many motor axis revoluons equal one revoluon of the load
axis.
The gearbox rao is congured using a quoent (numerator/denominator).
The gearbox rao for the motor is inuenced by 4 parameters:
•
Gearbo
x factor numerator 40x500A:033
•
Gearbox factor denominator 40x500A:034
•
Addional gearbox factor numerator 40x500A:025
•
Addional gearbox factor denominator 40x500A:026
The gearbox
rao for the second encoder is inuenced by 2 parameters:
•
Gearbo
x factor numerator 40x500B:033
•
Gearbox factor denominator 40x500B:034
Example:
Aer 58,667 rotaons (i) of the motor axis, the spindle turns once.
