The improper setting could lead to unexpected fast rotation so make sure to set them in the state
of SERVO OFF. The range of the electronic gear ratio is . If the setting
value is outside this range, the operation of motor may not be performed. The relationship of electronic
gear numerator and electronic gear denominator is plotted below.
4 electronic gear numerators are available for users to select. Enable the function CM1 and CM2 of DI
to switch. See the table below.

Calculation of electronic gear ratio
Before calculating this value, users have to know the specifications the motor encoder resolution
(2

=4194304ppr), the reduction rate, gear ratio of machine. Use the following equation to calculate the
electronic gear ratio.
