6.3.6.2. RS-232C Communication Operation
 In the velocity control mode and torque control operation, the Motor rotational velocity and output torque
can be directly controlled by the RS-232C communication command.
 Setting of the parameter AC (AC0) enables the DC command.
Then, the Motor is controlled by the rotational velocity and the output torque proportional to the data
value.

Caution • Depending on the parameter DI setting, the polarity of the DC command is
reversed.
• The shipping set value of the parameter DI is "0."
(The CW direction viewed from the Motor rotor is count-up.)
• The rotational velocity of the Motor is limited depending the Motor type.
