4.4First Switch On
The Getting Started Guide or Operating Instructions that are supplied with the inverter will give detailed instructions on how to start and set up the inverter. However, some general points are worth noting:
·The inverter will usually operate a standard motor and load without changing the factory settings.
·To optimise performance, and for special applications, the factory settings may be changed. This is usually achieved by adjusting parameters, which are programmable settings that control various characteristics of the inverter. Parameters are usually set via a keypad or computer, and are normally stored by the inverter even after the power is switched off. The procedure for changing parameters is described in the the Operating Instructions.
·If too many parameters are changed, and performance is not as required, it may be advisable to reset all parameters to the factory setting and start again.
·‘Quick set up’ or ‘Commissioning’ programmes may simplify programming and parameter setting. Check the ‘Getting Started Guide’.
·If there is a problem with the inverter or its settings, the display will usually flash or otherwise indicate a fault or warning. The handbook will suggest a trouble shooting procedure.
·If the motor goes in the wrong direction, switch off at the supply, wait five minutes for the internal capacitors to discharge, and swap any two motor connections. Of course, the motor can also be reversed using the front panel controls, digital inputs etc.
·If the motor is heavily loaded, or if the parameters have not been correctly set it may not turn. Set the motor parameters as described in the Operating Instructions.
