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.)
