Make sure that this instruction manual is delivered to the end user of the inverter unit. 2. Read this manual before installing or operating the inverter unit, and store it in a safe place for reference. Inspection and maintenance Warranty Disposal of the inverter E6581301 I. Safety precautions The items described in these instructions and on the inverter itself are very important so that you can use the inverter safely prevent injury to yourself and other people around you as well as prevent damage to property in the area. Thoroughly familiarize yourself with the symbols and indications shown below and then continue to read the manual. [. . . ] To make an adjustment so that the frequency reaches its peak value at the maximum voltage and current, decrease the gain of the analog terminal in use. Note that specifying a too small value may cause the operation frequency not to reach the maximum frequency, even though the maximum voltage and current are applied. 6. 29 Operating a synchronous motor , , : PM motor constant 1 : Step-out detection current level/ detection time This parameter is used only when the inverter is used with a synchronous motor. If you intend to use your inverter with a synchronous motor, contact us at the your supplier.
