value
Change
06 Numerator 0 of electronic gear 1 to 67108864 (in increments of 1) 16 Always
07 Denominator of electronic gear 1 to 67108864 (in increments of 1) 1 Always
These parameters are enabled only under position control.
With these parameters, the traveling amount of the mechanical system per each command pulse is
adjusted to a unit amount.
If parameter PA1_05 is "0," the settings of these parameters are enabled.
The following equation is used to calculate.
 Equation of numerator 0 of electronic gear and denominator of electronic gear
Cancel down so that numerator 0 divided by the denominator of the electronic gear is an integer
(67108864 or less).
* The unit amount is "1," "0.1," "0.01," "0.001," etc. Its unit is [unit].
* The number of encoder pulses is 16777216 for a 24-bit encoder.
