Maximum Torque/Power
CFN: Max T/P
09 105 %
10 – 325 % of Torque/Power (Default: 105%)
Start Mode (CFN 01) set to Open Loop Voltage Acceleration:
Not used when the Start Mode (CFN 01) parameter is set to open-loop voltage acceleration. When in open
loop voltage acceleration mode, the final voltage ramp value is always 100% or full voltage.
Start Mode (CFN 01) set to Current Control Acceleration:
Not used when the Start Mode (CFN 01) parameter is set to current control acceleration mode. Refer to the
Maximum Current 1 (CFN 04) parameter to set the maximum current level.
Start Mode (CFN 01) set to TruTorque Control Acceleration:
This parameter sets the final or maximum torque level that the motor produces at the end of the acceleration
ramp time. For a loaded motor, the maximum torque value initially should be set to 100% or greater. If the
maximum torque value is set too low, the motor may not produce enough torque to reach full speed and may
stall. On lightly loaded motors, this parameter may be reduced below 100% to produce smoother starts.
z NOTE: It is important that the Rated Power Factor (FUN 06) parameter is set properly so that the desired
maximum torque level is achieved.
Start Mode (CFN 01) set to Power Control Acceleration:
This parameter sets the final or maximum power (KW) consumption level that will be achieved at the end of
the ramp time. For a loaded motor, the maximum power value initially should be set to 100% or greater. If
the maximum power level is set too low, the motor may not produce enough torque to reach full speed and
may stall. On lightly loaded motors, this parameter may be reduced below 100% to provide for smoother
starts.
z NOTE: It is important that the Rated Power Factor (FUN 06) parameter is set properly so that the actual
maximum power level is achieved.

Acceleration Ramp Profile

10 Linear
Linear, Square, S-Curve (Default: Linear)
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.
