DOK-INDRV*-MP*-02VRS**-FK01-EN-P

When the drive is switched on again (after initial commissioning), the

correction values stored in parameter P-0-0342, Correction value table

for encoder correction are automatically activated when the respective

bit was set in P-0-0341, Control word for encoder correction!

Axis Error Correction

Brief Description

The actual position value provided by the measuring system can differ

from the real actual position value at the axis, e.g. at the point of chip

removal in the case of metal-cutting machining, due to...

• inaccuracy of the measuring system

• transmission inaccuracy in mechanical transmission elements such as

gear, clutch, feed spindle etc.

• thermal expansion of machine parts of the drive system.

For compensating the mechanically determined position error sources,

IndraDrive controllers provide the following correction functions:

• backlash on reversal correction

• precision axis error correction

• control-side axis error correction

Only one of the three above correction functions can be active at a time. If

more than one should have been activated, only the correction function of

highest priority is active, the order of the above list is according to

increasing priority. If several correction functions are activated

simultaneously, only the one of highest priority takes effect!

In addition, it is possible to activate the temperature error correction.

IndraDrive controllers provide two possibilities of correcting temperature

errors:

• independent of axis position

• depending on axis position

The two possibilities of temperature error correction can be activated

simultaneously and in addition to the other correction functions!

• P-0-0404, Axis correction actual temperature pos.-dependent

• P-0-0405, Axis correction actual temperature pos.-independent

• P-0-0406, Axis correction temperature factor pos.-dependent

• P-0-0407, Axis correction temperature factor pos.-independent

• P-0-0408, Axis correction start position

• P-0-0409, Axis correction end position

• P-0-0410, Axis correction support point distance

• P-0-0411, Axis correction, correction table positive
