Manual Auto-Gain Tuning (Basic) - Panasonic minas a4 series Instruction Manual

Manual Gain Tuning (Basic)
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 adjusted properly depending on the limitation on
load conditions. Or you might need to readjust the tuning to obtain the optimum response or stability corre-
sponding to each load.
Here we explain this manual gain tuning method by each control mode and function.
Before Making a Manual Adjustment
You can adjust with the sound or motor (machine) movement by using the front panel or the console, how-
ever, you can adjust more securely by using wave graphic function of the setup support software, PANATERM
or by measuring the analog voltage waveform using a monitoring function.
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 Pr07
(Selection of speed monitor) and Pr08 (Selection of torque monitor).
For details, refer to P.41, "Wiring to the Connector, CN X5" of Preparation, and "Parameter Setup" of each
control mode.

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.276, "Outline of the Setup Support Software,
