Electronic Gear Function
The Electronic Gear Function controls the position by using the value that is obtained by multiplication
of the position command input from the host controller by the specified gear ratio.
The Electronic Gear Function can be used when the communications period is 250 µs or more. When
the communications period is 125 µs, set the gear ratio to 1:1.
When the Servo Drive is connected to an OMRON Machine Automation Controller NJ/NX-series CPU
Unit, the electronic gear ratio is set on the controller. Set the electronic gear ratio to 1:1 on the Servo
Drive.
Note If the unit version of the NJ/NX-series CPU Units is 1.10 or earlier, some Servomotors cannot be driven at
the maximum rotation speed. In such a case, set the electronic gear ratio of the Servo Drive to 2:1 or
higher.
When the Servo Drive is connected to an OMRON Position Control Unit (Model: CJ1W-NC
8
), set
the electronic gear ratio to 8:1 or higher on the Servo Drive.
Precautions for Correct Use
To make the position command smoother after the electronic gear setting, adjust it by using the
Position Command Filter
(3011 hex).
