9.4.6.5 Traversing to fixed stop
Description
The "Travel to fixed stop" function can be used, for example, to traverse sleeves to a fixed
stop against the workpiece with a predefined torque. In this way, the workpiece can be
securely clamped. The clamping torque can be parameterized in the traversing task (p2622).
An adjustable monitoring window for travel to fixed stop prevents the drive from traveling
beyond the window if the fixed stop should break away.
In positioning mode, traversing to a fixed stop is started when a traversing block is
processed with the FIXED STOP command. In this traversing block, in addition to the
specification of the dynamic parameterized position, speed, acceleration override and delay
override, the required clamping torque can be specified as task parameter p2622. From the
start position onwards, the target position is approached with the parameterized speed. The
fixed stop (the workpiece) must be between the start position and the braking point of the
axis; that is, the target position is placed inside the workpiece. The preset torque limit is
effective from the start, i.e. traversing to fixed stop also occurs with a reduced torque. The
preset acceleration and delay overrides and the current speed override are also effective.
Dynamic following error monitoring (p2546) in the position controller is not effective when
traveling to the fixed stop. As long as the drive travels to the fixed stop or is in fixed stop, the
"Travel to fixed stop active" status bit r2683.14 is set.
