General introduction to the electronic cam module

Introduction

The TSX CCY 1128 electronic module is designed to control 24 discrete physical outputs independently and with a very short response time (<0.2ms).

The TSX CCY 1128 module operates on a Premium PLC (software version 3.3 or above).

The software installation is performed using the Control Expert software.

Areas of application

The TSX CCY 1128 module can process applications with the following types of movement:

non-reversing rotary (eg.: mechanical presses)
alternating (eg.: hydraulic presses, transfer machines)
cyclical, with periodic entry of parts to be processed (eg.: packaging machines)
continuous, with random entry of parts to be processed (eg.: conveyors)

Main characteristics

This table summarizes the main functional characteristics of the electronic cam module.

Characteristic	Value
Number of cams	128 maximum
Number of tracks	32 (24 directly associated with the 24 physical outputs, 8 logical)
Position encoder inputs	incremental or absolute
Outputs controlled	24 discrete outputs 24V, 0.5A
Types of cam	position, monostable, brake
Associated Functions	taking up axis backlash, recalibrating the position, capturing the readings, switching feed forward, parts counter, generation of events.

Recalibration

This is the module function which is used to adjust the axis in relation to the machine zero or to synchronize the axis in relation to the arrival of a part.

Recalibration forces the position reading to a value which is predefined by the "recalibration value" parameter (included in the pulse field of the cycle).

The module allows recalibration to be carried out systematically for each cycle or for only one cycle. This recalibration is always conditioned to the IREC input.

Capture

A module function that is used to sample the position value of the axis on detection of a precise event (input Icapt0 and/or Icapt1). The capture has no impact on the values of the axis nor on the cam processor.

The implementation of this function allows the application to manage the process better, for example: in monitoring the number of pulses sent by the encoder, the size of the parts, the axis slip, the angle of arrival of the parts.

Anticipation

Cam processor function that is used to compensate for the delay caused by the machine’s actuators.

The anticipation value is applied to all changes of track status. It is specified by the "anticipation factor" defined in the recipe parameters (value between 0 and 32 767 x 50 micro seconds).
