09F4S1D3420

Product Description

The 09F4S1D3420 is a drive inverter KEB COMBIVERT featuring a high-quality and dynamic operation. The unit has a user-friendly interface and with a status display to help the user understand all that is taking place with the unit. The status display will show a message with all the working conditions of the inverter.

The 09F4S1D3420 features an adjusted frequency that allows the inverter to realize its maximal output voltage. Ensure that rated frequency is properly adjusted to prevent overheating of the motor. At lower speed ranges, the motor voltage will decrease largely on the stator resistance. To maintain the breakdown torque of the motor, the boost can help to compensate for the decrease in voltage across the entire speed range. Among the functions that this inverter KEB COMBIVERT is capable of is the max ramp current. This is a protection function. It protects the inverter from turning off if there is an overcurrent during the acceleration ramp. Upon reaching the adjusted value the ramp will be stopped until there is another decrease in current. At this point, the display unit will be showing a code of “LAS”.

Another function of the 09F4S1D3420 is the max constant current. This is another protective function which protects the unit from switching off in the event of overcurrent during a constant output frequency. The output frequency will reduce if the adjusted value is exceeded. The display unit will display the code “SSL”. The unit has an operating drive mode that allows for the manual start of the operator. With the controlled release value set, the keyboard exclusively presets the rotation. The display unit will display error messages that are denoted with the initial letter of “E” along with a corresponding error in the KEB COMBIVERT display.
