• 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.
