Remove the earth bolts (EM13). *See the user s manual. Do t use an RFI filter with a ne diret earthed mains supply. As the supply would otherwise onnet with the earthpotential via the filter apaitors. * Ensure that powerful eletromagneti radiation reahes the adjaent low voltage supply. ** *) When this is t done on a mains supply with a ne diret earthed neutral point, it an result in a risk of personal injuries or damage to equipment. **) In some ases the natural interferene suppression in the transformers and ables an be suffiient. In the event of unertainty, a supply transformer with stati sreen between the primary and seondary windings an be used. Dimensioning and delivery of the sreen between the primary and seondary windings is t the responsibility of FläktGroup AB. INSTALLATION ACH550 may only be installed by a qualified eletriian. DANGEROUS VOLTAGES There are dangerous voltages in the onverter when the main voltage is onneted. Wait at least five minutes after the voltage has been disonneted before the protetive over is removed or the motor s onnetion box is opened. Measure the voltage aross the diret voltage terminals U, U before work is started. AUTOMATIC START ACH550 starts automatially when the supply voltage returns after a power failure if the external start order is ative. Chek whether the external start order is ative before the supply voltage is swithed on.

5 Installation and maintenane 5 ADJUSTMENT OF THE GAIN AND INTEGRATION TIME A low gain value and a long integration time guarantees a stable system, but an also result in inertia in the syatem. When the proportional gain value is too great or the integration time too short the system an beome unstable. The atual value from the sensor is read on parameter 0130 for PID1 and parameter 0131 for PID2. Proedure: Start with the following settings: 4001 GAIN = 0, INTEGRATION TIME = 20 seonds. Start the system and see whether it reahes the set point value quikly and establishes stable operation. If t, inrease GAIN (4001) until the atual value signal (or the drive system speed) osillates ontinuously. It may be neessary to start and stop the drive to indue this osillation. Lower GAIN (4001) until the osillation stops. Set GAIN (4001) to between 0,4 till 0,6 times the value above. Lower the INTEGRATION TIME (4002) until the feedbak signals (or drive system speeds) osillate ontinuously. It may be neessary to start and stop the drive to indue this osillation. Inrease the INTEGRATION TIME (4002) until the osillation stops. Set the INTEGRATION TIME (4002) to between 1,15 to 1,5 times the value above. If the feedbak signal ontains high frequeny ise, inrease the value of parameter 1303 FILTER AI1 or 1306 FILTER AI2 until the ise is filtered out from the signal.
