5-131 Before Using the Products2 Preparation3 Connection4 Setup5 Adjustment6 When in Trouble7 SupplementAs explained previously, MINAS-A4 series features the automatic gain tuning function,however, there might be some cases where this automatic gain tuning cannot be adjust-ed properly depending on the limitation on load conditions. Or you might need to readjustthe tuning to obtain the optimum response or stability corresponding to each load.Here we explain this manual gain tuning method by each control mode and function.Before Making a Manual AdjustmentBy monitoring waveforms using the waveform graphic function of the setup support soft-ware PANATERM installed on the PC or by measuring the analog voltage waveform withthe help of the monitor function, accurate adjustment can be positively, quickly and easilydone when compared with that performed on the front panel.1. Analog monitor outputYou can measure the actual motor speed, commanded speed, torque and deviationpulses by analog voltage level by using an oscilloscope. Set up the types of the signalsor the output voltage level with Pr4.16 (Selection of speed monitor) and Pr4.21 (Selec-tion of torque monitor).2. Waveform graphic function of the PANATERMYou can display the command to the motor, motor movement (speed, torque commandand deviation pulses) as a waveform graphic on PC display.
