As 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 readjust
the 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 Adjustment
By 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 with
the help of the monitor function, accurate adjustment can be positively, quickly and easily
done when compared with that performed on the front panel.
1. Analog monitor output
You can measure the actual motor speed, commanded speed, torque and deviation
pulses by analog voltage level by using an oscilloscope. Set up the types of the signals
or 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 PANATERM
You can display the command to the motor, motor movement (speed, torque command
and deviation pulses) as a waveform graphic on PC display. Refer to P.7-26, "Outline
of the Setup Support Software, PANATERM" of Supplement.
