Note 3. Check the offset amount to stop the Servomotor in both forward direction and reverse direc-

tion, and then set the center value accordingly.

4-11-6 Analog Monitor Output Adjustment

• The following two types of analog monitor output adjustment can be performed using System Check

Mode.

• Analog monitor output offset manual adjustment (Fn00C).

• Analog monitor output scaling (Fn00d)

Note 1. Set the monitor items to be output from the analog monitor using Pn003.0 (analog monitor 1

(AM) allocation), and Pn003.1 (analog monitor 2 (NM) allocation).

Note 2. The maximum analog monitor output voltage is 8 V. Exceeding this value may result in an

abnormal output.

Note 3. Analog monitor output accuracy is approximately 15%

H Analog Monitor Output Offset Manual Adjustment (Fn00C)

• Use this function to adjust the analog output monitor offset. You can adjust each of the two monitor

outputs separately.

• The analog monitor output offset adjustment range is –128 to 127 (x 17 mV).

Note When adjusting the analog monitor output offset, confirm that the output voltage is zero (e.g., if

outputting the Servomotor rotation speed, confirm that the servo is OFF and the Servomotor shaft

is not moving) before connecting the measuring instrument to be used.
