Voltage Ramp Start ConfigurationDefault values may be used for start time and initial torque.Kick Start Torque = 0% (fans and pumps), 75% (high breakaway loads)Kick Start Time = 0 sec (fans and pumps), 1 sec (high breakaway loads)Start the motor and determine the worst case starting conditions. Adjust initial torque forsmooth start without hesitation. Motor rotation should begin within two seconds.If stall faults occur at the end of the ramp time, increase Initial Torque, Kick Start Torque andTime and/or Soft Start Time to get into bypass before the Soft Start Time elapses. Also, verifythat the motor is not overloaded.2. Current Limit Start ConfigurationInitial settings:Initial Torque = 50%Soft Start Time = 60 secKick Start Torque = 0%Kick Start Time = 0 sec (disabled)3. Start the motor and determine the worst case starting conditions. Adjust Initial Torque forsmooth start without hesitation. Rotation should begin within two seconds and the motorshould smoothly accelerate to full speed.4. If stall faults occur, increase Initial Torque and/or Soft Start Time to get into bypass before theSoft Start Time elapses. Also, verify that the motor is not overloaded. Verify that the motor isnot in a stall condition. A stall condition will be noted when the motor does not continue toaccelerate during the start ramp.5. After suitable performance has been achieved, determine the starting time to bypass and setSoft Start Time at 1.25 times this time. For example, if it takes 10 seconds to accelerate themotor and go into bypass, set the Soft Start Time for 12.5 seconds. Adjust the Soft Stop Timefor the desired stopping time.Fault FCUser InterfaceMode LED P/O LED DisplayPhase reversal 24 Protection Phase sequence F.24Stall 25 Protection Stall trip % F.25SCR overcurrent 27 None None F.27Under load 28 Protection Under load F.28Current imbalance 29 Protection Current imbalance % F.29Phase loss 30 Protection Phase loss % F.30Voltage imbalance 31 Protection Voltage imbalance % F.31Jam 33 Protection Jam trip % F.33Contactor overcurrent 34 None None F.34Missing temp sensor 35 None None F.35www.comoso.com
