[. . . ] This parameter should be set to a level that allows the motor to begin acceleration with a few seconds of a start command being received. The default value for initial torque is 20%. Values Default Max Torque (maximum torque) Description The maximum torque parameter sets the final level of torque that is supplied to the motor during starting. For a loaded motor, the maximum torque parameter 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 (UTS). On a lightly loaded motor this parameter may be reduced below 100% to provide for smoother starts. The default value for the maximum torque parameter is 105%. Values Default 52 4. 7 PROGRAMMING: Starter Setup - TruTorque Ramp Ramp Time Description The ramp time parameter sets the time it takes for the commanded torque to go from the Initial Torque Setting to the Maximum Torque Setting. If the ramp time expires before the motor reaches full speed the starter will maintain the set Maximum Torque level until either the motor reaches full speed, the stall (UTS) timer expires, or the motor thermal overload trips. It is not the same ramp time parameter that is used for current ramp profile starts. Note: Setting the ramp time to a specific value does not necessarily mean that the motor will take this time to accelerate to full speed. The motor and load may achieve full speed before the ramp time expires if the application does not require the set ramp time and maximum torque to reach full speed. Alternatively, the motor and load may take longer than the set ramp time to achieve full speed. Values Default The TruTorque ramp time is adjustable from 0 to 120 seconds in 1 second intervals. The default value for the TruTorque ramp time is 15 seconds. TT Over Cu (TruTorque overcurrent trip) Description The TruTorque overcurrent trip parameter is set as a percentage of FLA. If the motor current remains above this level for longer than the delay time the starter will trip. In order to protect applications such as pumps from water hammer when a fault does occur a normal deceleration profile will occur to "gracefully" shut down the system before the TruTorque Overcurrent Fault is displayed and the starter is disabled. Note: The TruTorque Overcurrent Trip only operates during TruTorque ramping before the starter has indicated an up-to-speed condition. If overcurrent protection is desired after the motor has come up to speed the Over Current parameter under the Motor Protection menu must be used. Values The TruTorque overcurrent can be set to Off or from 100% to 800% of FLA in 1% increments. The default value for the TruTorque Overcurrent parameter is Off Default Ovr Cur Dl (TruTorque overcurrent trip delay) Description The TruTorque overcurrent trip delay parameter sets the time that the motor current must exceed the TruTorque Overcurrent Trip setting, while the starter is ramping, before a trip will occur. The TruTorque overcurrent delay parameter can be set from 0. 1 to 90. 0 seconds in 0. 1 second intervals. The default value for the TruTorque overcurrent delay parameter is 0. 1 seconds. Values Default 53 4. 7 PROGRAMMING: Starter Setup - TruTorque Ramp TT DCL Tim (TruTorque deceleration time) Description The TruTorque deceleration time sets how quickly the motor decelerates. To make the motor decelerate at a slower rate increase this time or to make the motor stop quicker decrease this time.
