6.3.2. Analog Velocity Command Operation
l Velocity of the Motor may be directly controlled with the analog velocity command in the
velocity control mode.

6.3. Velocity Control Mode Operation
à Voltage range of the analog command is ± 10V. Offset adjustment is possible using the
adjusting pod (VR1) on the front panel of the Driver Unit or setting the parameter AF.
(Refer to "6.3.2.2. Offsetting Analog Command.")
à It is possible to set dead band of command voltage. (Refer to "6.3.2.1. Dead Band Set
to Command Voltage.")
à The parameter AC selects the polarity of command voltage. (Refer to Table 6-14.)
à Relation between the command voltage and the velocity may be selected with the
parameter AGV. (See Figure 6-23.)
à You may set a limit to steep changes in acceleration and deceleration induced by
velocity commands. (Refer to "6.3.3. Function to Limit Acceleration / Deceleration."
