Manual Gain Tuning (Basic)
As explained previously, MINAS-A4P 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 limita-
tion 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
You can adjust with the sound or motor (machine) movement by using the console, however, 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
SV.Pr07 (Speed monitor (SP) selection) and SV.Pr08 (Torque monitor (IM) selection).
For details, refer to P.49, "Wiring to the Connector, CN X5" of Preparation, and P.56, "Parameter Setup" of
Setting.
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.103, "Outline of the Setup Support Software,
PANATERM
® ".
