63 Electronic Gear Switching
With the following parameters, it is possible to switch between maximum of 4 numerators of the command
scaling by using DIV1 and DIV2.
For the command scaling function, please refer to 4-2-2 “Command Scaling (Electronic Gear).”
(1) Scope of application
□This function is applicable only when the following conditions are satisfied:
perating conditions for specified frequency division multiplication switching function
Action state In Servo On status.
Factors other than control parameters such as the deviation counter clear and com-
mand pulse inhibition inputs and the torque limit are appropriately configured and do
not cause any problem in normal motor rotation.

To set the numerator used for the command scaling performed for the
command pulse input.
Is valid when Pr0.08 “Command pulse counts per one motor revolution “ is
0.
For position control, when the value is set to 0, the encoder resolution is set
to the numerator. For full-closed control, when the value is set to 0, the
command scaling ratio forcibly becomes 1:1.
