Optimized releasing of the axis clamp via travel command
If a clamped axis is to be traversed in continuous-path mode, a travel command is issued for
the clamped axis in the rapid traverse blocks (
G0
) immediately before the traversing block of
the clamped axis. This way, the PLC user program can release the axis clamp again in time.
(The travel command is set a maximum of two rapid travers blocks prior (including
intermediate blocks) to retain the reference to the initiating part program block).
Parameterization:
MD36052 $MA_STOP_ON_CLAMPING = 'H03' (Special function for clamped axis)
Prerequisites for the PLC user program
•
The axis is removed from the clamp as soon as a travel command is pending.
•
The axis may be removed from the clamp even if only during positioning (
G0
).
The following image shows an example of the interface signals and states upon releasing of
the axis clamp:
