# Select and deselect compensation

## Activate/deactivate

By analogy to other compensations, compensation can be activated by a parameter in the axis list or additionally by an NC command.

## Enable use/activate

Compensation can only be applied if the parameter P-AXIS-00522 is set (TRUE) in the parameter list and the compensation value list is parameterised.

## Behaviour after start-up

When friction compensation is selected, it is active directly after controller start-up regardless of whether homing was executed.

## Programming

In every case, compensation can also be activated or deactivated explicitly by the axis-specific COMP command in the NC program.

## Attention

The COMP command is valid after program end. After activating or deactivating compensation, the operator must also explicitly deactivate or activate it at program end.
