3.2.2. Velocity Control with Analog Command
Velocity of the Motor may be directly controlled with the analog velocity command in the
velocity control mode.
Voltage range of the analog command is ± 10V. Offset adjustment is possible setting
parameter AF. (Refer to “3.2.2.1. Offsetting Analog Velocity Command.”)
Parameter AC selects the polarity of command voltage. (Refer to Table 3-2.)
Relation between the command voltage and the velocity may be selected with parameter AG.
(See Figure 3-3.)
