Velocity Mode Submode Group

Analog Radio Button
Selecting this radio button puts the drive into Analog submode. In Velocity mode the drive
develops velocity in proportion to the voltage received on the Analog Input. The Analog Input
is scaled to the Analog Velocity Command by the Full Scale Velocity, Analog Input Full
Scale, and Analog Input Zero Offset parameters.
For example:
+5V = 2000 RPM CW
-5V = 2000 RPM CCW
Analog Input Full Scale = 10V
Full Scale Velocity = 4000 RPM
Figure 25: Operating Mode, Velocity Mode Selected
Full Scale Velocity
This parameter is the maximum motor velocity (in RPM) desired when the drive receives an
analog voltage equal to the Analog Input Full Scale parameter setting.
Note
Full Scale Velocity and Analog Input Full Scale do not set limits. They only set the
proportion of motor speed to Analog Input Voltage.
The Full Scale Velocity and Analog Input Full Scale parameters are used in the Analog or
Summation operating modes.
