Introduction to the step by step axes control environment
Introduction The configuration of a step by step axes control architecture is as follows:
Pulses Translator
TSX Premium
Step by step motor
TSX CFY 21
Step by step axes control environment
PL7 Junior/Pro
End of run and reference point cams
The step by step axes control environment for TSX Premium PLCs is made up of 2 modules: l l
TSX CFY 11 (1 limited linear axis),
TSX CFY 21 (2 independently limited linear axes).
The PL7 software integrates basic application-specific step by step movement supporting the programming of these step by step axes control modules.
Basic movements are driven from the machine’s principal sequential control program, but carried out and controlled by the TSX CFY modules.
These modules control the rotation speed of a step by step motor, its accelerations and decelerations by delivering a frequency command to a translator (fmax = 187
KHz). The translator transforms each impulse into a basic movement of the step by step motor.
Control of the step by step motor is carried out in open loop. End of run, reference point and event inputs allow the module to control the movements of the moving part on the axis.
Some translators include a step failure mechanism: this information is put at the disposition of the user program which can initiate a new reference point.
The step by step axes control environment also includes the TSX CXP 611 cable to link the TSX CFY11/21 modules directly to the MSD and MS translators from the manufacturer Phyton Lektronik GmbH.
