Degree unit [G] [WG]

This unit is available on servo amplifiers with firmware version B6 or later.

Summary

Using the degree function enables positioning in modulo coordinates (axes of rotation).
• This function can be used only in the profile position mode.
• This function cannot be used in the linear servo motor control mode. Enabling this function in the linear
servo motor control mode will trigger [AL. 037 Parameter error].
• If using this function in the fully closed loop control mode, use a rotary encoder as a load-side encoder.
Connecting a linear encoder will trigger [AL. 037].
• If the unit is set to "degree" in the profile position mode, relative position commands are disabled.
Attempting to start positioning operation after bit 6 (abs/rel) of [Controlword (Obj. 6040h)] has been set to
"1" (relative position command) will trigger [AL. 0F4.8 Control command input error warning] and the
operation will not start.
Precautions
• Setting the unit to "degree" will change the setting ranges of some objects.

• Use the electronic gear function to adjust the rotation amount of the servo motor relative to the position command (in
degrees). If the number of encoder units is extremely small for the position command (in degrees), the servo motor may not
rotate.
