Summation Submode
In Summation submode the Velocity Command is the result of the sum of the Velocity
Command Analog and the Velocity Command Preset values.:
Where:
VC = Velocity Command
AC = Velocity Command Analog
PC = Velocity Command Preset
Example 1:
Use of Velocity Presets in a phase advance/retard application. Velocity Preset #0 is set to 0
RPM, Velocity Preset #1 is set to +5 RPM, and Velocity Preset #2 is set to -5 RPM. The
Analog Input is the command source for a web application where a phase adjustment may be
useful. Without interrupting the operation, you may select either Velocity Preset #1 or #2 to
speed up or slow down the motor thereby advancing or retarding the phase between the motor
and the web material.
