Parameters for reduced velocity

Parametrisation

The following parameters are active when the user activates the real-time control signals in the PLC for

• reduced velocity or
• reduced velocity in the safety zone when the axis is in one of the two safety zones P-AXIS-00085, P-AXIS-00093 or P-AXIS-00097 and P-AXIS-00105.

This therefore limits the axis velocities travelled and not the path velocityto a predefined value.

The parameter P-AXIS-00214 defines the maximum velocity when the PLC signal is active:

gpAx[axis_idx]^.ipo_mc_control.reduced_speed

For rapid traverse motions, the parameter P-AXIS-00155 can set a deviating value. If the parameter P-AXIS-00155 is not assigned, the parameter P-AXIS-00214 is also used for rapid traverse motions.

The parameters P-AXIS-00030 and P-AXIS-00503 define the maximum permissible axis velocity in the safety zone when the PLC signal is active.

For zone 1 with associated reduced velocity:

gpAX[axis_idx]^.ipo_mc_control.reduced_speed_zone

or for zone 2 with associated reduced velocity:

gpAX[axis_idx]^.ipo_mc_control.reduced_speed_2_zone

Also define additional position limits for the zones.
