Command unit select function [G] [WG]

Position command unit selection function

This function is available on servo amplifiers with firmware version B6 or later.
The position command unit selection function can be used to select the position data command unit (pulse/degree) according
to the system being used.
For information on which control mode can be used with the unit "degree", refer to "Selecting control mode (Modes of
operation)" in the User's Manual (Communication Function).

• In the cyclic synchronous mode, "degree" cannot be used as the unit of position data. Setting "degree" will
not allow switching to the cyclic synchronous mode.
Precautions
• To adjust the rotation amount/travel distance of the servo motor relative to the position data in the command unit, use the
electronic gear function.
