6.3 Electronic Gear
122
6. Set the parameters.
Reduce the electronic gear ratio ( ) to the lower terms so that both A and B are integers smaller
than 1073741824, then set A and B in the respective parameters.
That is all that is required to set the electronic gear ratio.
Set the electronic gear ratio according to the machine specifications as described below.
• B = 8192 × [Servomotor shaft rotation speed]
• A = [Reference units (Load travel distance per load shaft one revolution] × [Load shaft rotation
speed]
