Custom Gains Attributes
Use this dialog box to configure properties related to Advanced Gain Attributes.
When a parameter transitions to a read-only state, any pending changes to parameter values are lost, and the parameter reverts to the most recently saved parameter value.
When multiple workstations connect to the same controller using the Logix Designer
application and invoke the Axis Wizard or Axis Properties dialog, the firmware allows only
the first workstation to make any changes to axis attributes. The second workstation
switches to a Read-Only mode, indicated in the title bar, so that you may view the changes
from that workstation, but not edit them.
Properties
The following attribute, or parameter, value can be monitored and edited in this dialog box:
Attribute/Parameter | Description |
VelocityDroop | This 32-bit unsigned attribute - also referred to as "static gain" - acts as a very slow discharge of the velocity loop integrator. VelocityDroop may be used as a component of an external position loop system where setting this parameter to a higher, non-zero value will eliminate servo hunting due to load/stick friction effects. This parameter only has effect if VelocityIntegralGain is not zero. Its value ranges from 0 to 2.14748x10^12.
TIP:
This value is not applicable for Ultra3000
drives.
