Calculation Method
• The Servomotor can be rotated for the number of pulses obtained by multiplying the command
• This function is effective under the following conditions:
• The following equation shows the relation between the number of internal command pulses (F)

pulses by the electronic gear ratio.
multiplied by the electronic gear ratio and the number of command pulses (f) per Servomotor
• When fine-tuning the position and speed of two lines that are to be synchronous.
• When using a position controller with a low command pulse frequency.
• When you want to set the machine travel distance per pulse, to 0.01 mm for example.
Parameter name
*1
*1
Set the pulse rate for command pulses and Servomotor trav-
el distance.
The upper limit of the gear ratio numerator is determined by
the following formulas.
• Electronic Gear Ratio Numerator 1
• Electronic Gear Ratio Numerator 2
Any higher setting will be invalid, and the numerator will be
4,194,304/(Pn4D+1). If the numerator is 0, the encoder res-
olution will be automatically set to the value of the numerator
and the number of command pulses per rotation can be set
in Pn4B.
