Instruction manual

Model 2090 Multi-Device Controller

OSCLr

Invokes the Overshoot Clear menu option. Pressing the ENTER key

will display SURE in the display. Pressing ENTER a second time

will clear the overshoot compensation values for this device.

Pressing any other key will abort the operation and perform the

associated action.

On occasion, certain motion error conditions, such as hardware limit

hit (E005), can cause the overshoot compensation values to become

corrupted, resulting in erratic behavior. The most common symptom

of this is that each time the device is commanded to move it will

move halfway to the target and stop. At this point, the automatic

updating of the overshoot compensation values is overridden and can

only be corrected by manually clearing the values. Once cleared, the

normal overshoot compensation will be restored after several motion

cycles of the device.

On/OFF

Refers to the Overshoot Compensation Enable/Disable parameter.

Pressing the INCRM and DECRM keys will toggle this between

overshoot compensation being on or off. Pressing the ENTER key

will save the selected setting.

For variable speed devices with creep capability, overshoot

compensation is not needed and will interfere with normal table

operation in the case of occasional overshoot events. Also, some

software designed to work with older ETS-Lindgren controllers

provide their own form of overshoot compensation. This can

typically be disabled within the software to allow the 2090 to control

overshoot compensation, but this parameter can also be used to allow

the software to provide the compensation instead.
