Page 17: Start-Up
Start-up What this chapter contains This chapter instructs in setting the drive parameters and in checking the system. Parameter settings The table below instructs in parameter settings for a drive with ACS800 Standard Control Program starting a four-pole motor (50 Hz). With these settings, the trim control can affect ±20 rpm to final speed reference (1% of the defined maximum speed limit). -
Page 18: Checking The Operation Of The Rsyc Unit
Setting Parameter value Additional information Select analogue input AI1 for actual 40.07 = AI1 BUF OUT signal from RSYC unit, 0 … 10 V. signal for PID controller. Below 5 V = supply line frequency exceeds drive output frequency. 5 V = Supply line frequency and drive output frequency are equal and phases match. -
Page 19: Checking Of The Trim Function And Synchronization
Action Additional information Check unit visually. Parameter settings on page 17. Set drive parameters according to instructions. However, switch Trim function off (parameter 40.14 = OFF) for the time being. Shift control panel to local control mode. Use LOC/REM key. Letter L on first row of display indicates local control. -
Page 20: Final Check
Actions Information Start drive and monitor panel and RSYC status LED. The following indicates successful Trim control loop: - Drive accelerates to speed reference which was defined above. - Output frequency starts oscillating around 50 Hz. - AI1 is 2.5 V … 7 V. - RSYC LED blinks the first time after 5 …... -
Page 21: Fault Tracing
Fault tracing What this chapter contains This chapter gives the troubleshooting information. Troubleshooting hints Trouble Cause Remedy Unit operates illogically The board is affected by radiated Ensure all cables that connect to the RSYC unit despite all connections and interference. BUF OUT signal is not are shielded and shields are properly grounded. -
Page 22: Measuring With An Oscilloscope
Measuring with an oscilloscope Checking the supply line (MAINS) and inverter output (INVRTR) signals from the board may be the only way to see what is actually happening if there is no SYNC signal. There is a potential interference risk as it is possible that the probes pick-up the interference and conduct it to the board circuits. - Page 23 When the signals are in synchronization, the oscilloscope shows the following waveforms. When there is a phase difference, the waveforms are as shown in the graphic below. When the frequencies are different, the signals move respective to each other. If the “speed”...
