Electronic Gear Function; Parameters Requiring Settings - Omron OMNUC G5 R88M-K series User Manual

6-6 Electronic Gear Function

This function controls the position by using the value multiplied the position command entered
on the Host Controller by the preset electronic gear ratio. The functions is used in the
POSITION CONTROL and FULL CLOSING CONTROL modes.
In speed or torque control, the number of encoder pulses from the motor is divided by the
electronic gear and converted to the command unit for feedback.

*1. The electronic gear ratio must be set between 1/1000 x and 1000 x. If it is set outside the range, the Parameter
setting error (Alarm No.93.0) occurs.
*2. If the Pn009 is set to 0, the encoder resolution is set to the numerator during full closing controls also.

Set the numerator of the electronic gear ratio.
If the set value is 0, the encoder resolution is automatically
set as the numerator.
• 131072 for a 17-bit absolute encoder
• 1048576 for a 20-bit incremental encoder
