6-4 Electronic Gear Function
• The electronic gear function enables the Servomotor to rotate at the number of pulses calculated by
multiplying the position command value by the electronic gear ratio.
• This function is enabled in position control mode.
*1 Switching among Electronic Gear Ratio Numerator 2 to 4 (Pn500 to Pn502) is performed using the electronic gear
switching input (GESEL1/GESEL2). The settings of GESEL1 and GESEL2 are as follows
Any values can be set in PN008, Pn009, and Pn010, however if an extreme electronic gear ratio is set,
the operation is not guaranteed. Set the electronic gear ratio to between 1/1,000 and 1,000.
