[. . . ] 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. Note: This ramp time setting is only used for TruTorque starts. 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. 58 5. 8 PROGRAMMING: Starter Setup - TruTorque Ramp 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 59 5. 9 PROGRAMMING: Motor Protection - Overload Overload Description The overload parameter sets the class of the electronic overload. The starter stores the thermal overload value as a percentage value between 0 and 100%, with 0% representing a "cold" overload and 100% representing a tripped overload. See page 11 for the overload trip time vs current curves. When the overload is set to not available (OFF), the electronic overload is disabled and another motor overload protection device must be supplied. When the overload is set to bypass (BYP), the electronic overload is disabled during starting and then the thermal content is charged to 90% once the starter gets up-to-speed. When the motor is up-to-speed, the RediStart Micro II will use a class 10 overload for the motor protection. Values The overload can be set to; · OFF - no thermal overload - class 1 through 40 overload · 1-40 · BYP - overload bypassed during starting, class 10 once up-to-speed The default value for the overload parameter is 10. Default 60 5. 10 PROGRAMMING: Motor Protection - Line Current % Imbalanc (percent imbalance) Description The percent imbalance parameter sets the allowable phase to average current difference that is allowed before the starter will shut down.
