Sets the level to notify the warning.
When the Operation Selection when Using Absolute Encoder is set to 0 (use as the absolute
encoder), if the absolute value of encoder multi-rotation number exceeds the set value, the Absolute
Encoder Counter Overflow Warning is output.
Gives the encoder serial number.
Gives the resolution per rotation.
Gives the one-rotation position of the encoder. When the phase-Z position is 0, if the motor rotates
counterclockwise as viewed from the motor load side, the encoder value increases.
Gives the number of encoder rotations. The encoder value increases each time the motor rotates
counterclockwise as viewed from the motor load side.
Obtains the total number of encoder errors via serial communications.
Gives the electric angle.
In the counterclockwise rotation, 0° indicates the position which is the zero cross point (rising) of the
phase-U inductive voltage.
The encoder value increases when the motor rotates counterclockwise, and the display range is from
0 to 359°.
Gives the one-rotation data of the encoder as the mechanical angle.
The encoder value increases when the motor rotates counterclockwise, and the display range is from
0 to 359°.
Gives the internal temperature of the encoder which is mounted on the motor, or the internal tem-
perature of the motor.
