When P04-05=0, the motor and the load are connected through the reduction gear.
Assuming that the reduction ratio of the motor shaft to the load machine side is n/m (motor rotate
m round, load shaft rotate n round), the calculation of the electronic gear ratio is as follows :

This model drive supports up to 2 sets of electronic gear ratios, and the gear ratio selection can be
completed by using the electronic gear ratio switching function FunIN.23.
