11.1.1 Overview

External data record selection 227

Application:

One of eight various workpieces should be made available at a data collection station. The number of the desired workpiece is set using a BCD selector switch. The transportation process is then triggered by a starting pulse.

Mark-referenced positioning 229

Application:

Pieces with lengths of between 100 mm and 500 mm should be cut from a plate roller. The cut-off positions are specified by marks on the plate. If two marks are separated by more than 500 mm, the plate should be pulled back to the last cut-off position.

Speed step profiling / comparator switching points 231

Application:

A bore spindle should be guided to the surface of the workpiece using a rapid feed movement. The bore is then bored to a defined depth using a considerably longer feed. When reversing the bore spindle, the unit should travel at a slow velocity while the drill is still in the bore. The remaining travel to the idle position is performed at a rapid speed.

The bore spindle should be switched on just before the boring process commences and should be switched off immediately after it has been removed from the bore. Movement of the conveyor belt should be blocked for as long as there is a risk of collision between the workpiece and drill.

SPEED SYNC 233

Application:

Cartons should be transferred from one conveyor belt (conveyor belt A), a belt operating at a very variable belt speed, to another conveyor belt (conveyor belt C), a belt which has a constant belt speed. This task should be performed using a transfer belt (conveyor belt B) installed between the two other belts. This belt receives cartons from conveyor belt A and, when triggered by a pulse, passes them on to conveyor belt B. In addition to this, when conveyor belt B is assigned, conveyor belt A should be blocked. Conveyor belt B is controlled by COMPAX.

Speed control mode 234

Application:

A centrifuge for manual operation should be operated by an operating mode switch. The centrifugal process should either be run at a permanently set speed or the test tubes should be removed, one after another, through the removal aperture. The shutter on the removal aperture must only be able to open when the centrifuge is at a standstill.

Fast start 236

Application:

Material should be fed to an extender stamping machine which operates at a maximum speed of 150 rpm. The material may only be supplied if the stamping tool is open and if the workpiece (already stamped) has been thrown up. The material supply should be released or blocked via a switch.

Implementing a torque converters 237

2 options are available for implementing a torque converters.
