Manual Tuning Window
Tuning gains are measured in Hertz in the Integrated Motion on the Ethernet/IP
network connection compared to the radians/second in the stand alone drive.
6.283185 Rad/Sec = 1 Hz.
The Manual Tuning window contains three sections:
Manual Tuning Section: This section lets you customize the configuration of
system tuning. The following two selections can be made:
• System Bandwidth: Changing this value adjusts the Position Loop and
Velocity Loop response. The value selected in this field changes the
Application Type selection in the Autotune window. Therefore, care must
be taken to NOT change this value after the individual gains have been
manually configured.
• System Dampening: Changing this value adjusts both the Dampening
factor and System Bandwidth values. Lowering the System Dampening
factor dramatically increases the System Bandwidth. Care must be taken
when changing this value to avoid machine damage. It is recommended
that small incremental adjustments be made to the System Dampening
while evaluating the overall system response. This value changes the
Application Type selection in the Autotune window. Therefore, care must
be taken to NOT change this value after the individual gains have been
manually configured.
