F1: Travel to fixed stop

3.1

Brief description

Function
With the "Travel to fixed stop" function, moving machine parts, e.g. tailstock or sleeve, can be
traversed so that they can apply a defined torque or force with respect to other machine parts
over any time period.
Characteristics
● Programmability using commands in the part program or synchronized action:
– Activating and deactivating the "Travel to fixed stop" function
– Setting the clamping torque
– Setting the monitoring window
● Manual intervention option using setting data:
– Activating and deactivating the "Travel to fixed stop" function
– Setting the clamping torque
– Setting the monitoring window
● Presettings using machine data
– Clamping torque
– Monitoring window
● Identifying the function status via NC/PLC interface signals
● Enable or acknowledgment options via NC/PLC interface signals
● Reading the reference and actual status of the function via system variable
● "Travel to fixed stop" is possible for axes and spindles.
● "Travel to fixed stop" is possible simultaneously for several axes and parallel to the
traversing of other axes.
● Multi-channel block search can be performed with calculation of all the required additional
data (SERUPRO).
● Simulated axis traversal in conjunction with "travel to fixed stop" and "torque reduction"
possible.
● "Vertical" axes can also be moved with FXS to a fixed stop.
