oLrP Voltage Ramp Open Loop Voltage acceleration ramp.
curr Current Ramp Current control acceleration ramp. (Default)
tt TT Ramp TruTorque control acceleration ramp.
Pr Power Ramp Power (kW) control acceleration ramp.
Description The Start Mode parameter allows the selection of the optimal starting ramp profile based on the application.
The closed loop current control acceleration ramp is ideal for starting most general-purpose motor
applications. Ex: crushers, ball mills, reciprocating compressors, saws, centrifuges, and most other
applications.
The closed loop TruTorque control acceleration ramp is suitable for applications that require a smooth torque
output from the motor during starting. Ex: centrifugal pumps, fans. The Tru Torque is also suitable for belt
driven applications to eliminate belt sequel that commonly occurs near full speed.
The closed loop power control acceleration ramp is ideal for starting applications using a generator or other
limited capacity source.
