6.3.6.3. Analog Input Operation

In the velocity control mode and torque control operation, the Motor rotational velocity and output torque
can be directly controlled by the analog input command input.

Analog command voltage range is ± 10 [VDC]. Setting of the parameter AF enables offset tuning. For
details, refer to “6.3.6.4 Analog Command Input Offset.”

The polarity of command voltage can be selected by the parameter AC for analog command input
selection. Refer to “Table 6-15: Analog input operation, rotational direction” for the setting regarding the
polarity and rotational direction of the command.

The relationship between the command voltage, and the rotational velocity and output torque can be
changed by the parameter AG for analog command gain. Refer to “Fig 6-25: Command voltage, and
Motor velocity and output torque
(AC1 and DI0)” for command voltage and rotational velocity.

Caution
• The rotational velocity of the Motor is limited depending on the Motor type.
• When using the Motor with the maximum rotational velocity less than 10
[s
-1
], tune the parameter AG for analog command gain so that the
rotational velocity does not exceed the maximum rotational velocity.
