Its purpose is to estimate themotor initializing is carried out (parameter 14-22 OperationMode), the programmable parameters of the frequencyconverter return to their default parameter 14-22 Operation Mode does notinitialize communication duty cycleAn intermittent duty rating refers to a sequence of dutycycles. Each cycle consists of an on-load and an off-loadperiod. The operation can be either periodic duty or none-periodic local control panel makes up a complete interface forcontrol and programming of the frequency converter.

8 Thecontrol panel is detachable and can be installed up to 3 mfrom the frequency converter, that is, in a front panel withthe installation kit significant for Mille Circular Mil, an American measuring unit forcable cross-section. 1 MCM significant parametersChanges to on-line parameters are activated immediatelyafter the data value is changed. To activate changes to off-line parameters, press [OK].PI controllerThe PI controller maintains the speed, pressure,temperature, and so on, by adjusting the output frequencyto match the varying current parameter settings in 2 set-ups. Change between the2 parameter set-ups and edit 1 set-up, while another set-up is compensationThe frequency converter compensates for the motor slip bygiving the frequency a supplement that follows themeasured motor load keeping the motor speed logic control (SLC)The SLC is a sequence of user-defined actions executedwhen the associated user-defined events are evaluated astrue by the temperature-dependent standard busIncludes RS485 bus with FC state entered in fault situations, for example, if thefrequency converter is subject to an overtemperature orwhen the frequency converter is protecting the motor,process, or mechanism.

9 Restart is prevented until the causeof the fault has disappeared and the trip state is canceledby activating reset or, sometimes, by being programmed toreset automatically. Do not use trip for personal lockA state entered in fault situations when the frequencyconverter is protecting itself and requiring physicalintervention, for example, if the frequency converter issubject to a short circuit on the output. A trip lock canonly be canceled by cutting off mains, removing the causeof the fault, and reconnecting the frequency is prevented until the trip state is canceled byactivating reset or, sometimes, by being programmed toreset automatically.
