The unit for performing positioning using a DeviceNet Unit is determined by the following
two parameters.
No. Name
Pn810
Electronic Gear Ratio G1
(Numerator)
Pn811
Electronic Gear Ratio G2
(Denominator)
The electronic gear function can be used to set the position command units equal to the
amount of encoder pulses. The host controller can generate position commands in more
familiar user-defined units such as millimeters or inches.
Not Using the Electronic Gear
If not using the electronic gear, set Pn810 and Pn811 to 1. This will set the command unit to
1 pulse, so you must calculate the scale position units using the host controller.
