Range Linear (Default)

Description Linear – The linear profile linearly increases the control reference (voltage, current, torque, power, speed)
from the initial acceleration ramp value to the final acceleration ramp value. The linear profile is the default
profile and is recommended for most acceleration and deceleration situations.
Squared – The squared profile increases the control reference (voltage, current, torque, power, speed) in a
squared manner. A squared acceleration profile can be useful when using TruTorque control on a load with a
squared torque characteristic (such as pumps, and fans). A squared torque profile can provide a more linear
speed profile during acceleration and deceleration.
S–Curve
– The S-curve profile slowly increases the control reference’s rate of change at the beginning of the
ramp profile and an slowly decreases the rate of change of the reference at the end of the ramp profile. This
profile can be useful when using closed loop tach control to smooth the starting and ending of the acceleration
profile. It can also be useful with other types of control methods that require extra smooth starts.
