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 supported only in the Position
Control when the communications cycle is 1, 2, or 4 ms.
For communications cycles for which the electronic gear is not supported (250 or 500 µs), a Function
Setting Error (Error No. 93.4) will occur if the electronic gear is enabled.
Additional Information
When connected to an OMRON Machine Automation Controller (Model:
NJ301-
electronic gear ratio is set in the controller. Set the electronic gear ratio in the Servo Drive to 1:1.

*1 The electronic gear ratio must be set between 1/1,000 and 1,000. If it is set outside the range, an Object
Setting Error 1 (Error No. 93.0) will occur.
Whether the electronic gear is enabled/disabled is determined from the setting of the objects. If the gear ratio
setting is 1:1, the electronic gear is disabled.
