# Maximum permissible axis velocity in security zone (P-AXIS-00030)

P-AXIS-00030 | Maximum permissible axis velocity in security zone
Description | The parameter defines the maximum permissible axis velocity inside the security zones 1 and 2 if the control signal is active. Activation for security zone 1 is executed by the “Reduced velocity in zone 1“ control unit. This security zone is limited by the position limits given by P-AXIS-00093 and P-AXIS-00085.

Activation for security zone 2 is executed by the “Reduced velocity in zone 2“ control unit. This security zone is limited by the position limits given by P-AXIS-00105 and P-AXIS-00097.

Parameters of permissible axis velocities inside the security zone 1
Parameters of permissible axis velocities inside the second security zone

Remark on active acceleration during the deceleration phase:

The effective acceleration during deceleration depends on the following factors:

- the channel parameter P-CHAN-00097
- the time of activation of a particular security zone signal in the PLC
  (“Reduced velocity in zone 1“/ “ control unitReduced velocity in zone 2“) control unit
- the current axis position at this time in relation to the zone.

If the axis is outside the zone at the time of signal activation, the axis decelerates at the acceleration value of P-AXIS-00004 . If the axis is inside the zone, the axis decelerates at the acceleration value of P-AXIS-00024 .
