Gearbox ratio (C1202/C1203)
The gearbox ratio specifies the number of revolutions of the motor axis at which the
spindle revolves exactly once.
It is entered into the codes C1202 (gearbox factor numerator) and C1203 (gearbox factor
denominator). For the example described above, it follows that:
Gearbox ratio (i) +
1239 [rev. ńmin.]
100 [rev.
ńmin.]
+ 12.39
