The axes control modules offer application inputs and outputs for each axis which allow you to implement the different functions.
The following structural breakdown presents the inputs/outputs associated to a channel:
Application inputs/outputs
The step by step axes control modules offer for each of the axes:
for auxiliary inputs/outputs:
-
one cam reference point input,
-
two end of run inputs,
-
one event input,
-
one emergency stop input,
-
one external stop input,
-
one static output for the axis brake.
for translator inputs/inputs:
-
one translator check input,
-
one step failure control input,
-
one differential translator validation output,
-
two differential pulse outputs, one positive, one negative,
-
one differential step by step motor boost output,
-
one differential step failure reset output.
In Control Expert language, each movement is described by a SMOVE movement control function. From this SMOVE command and the position of the moving part, the TSX CFY module creates the position/speed setpoint and generates the pulses for this movement.
Configuration and control parameters
These parameters are used to define the specifications of use, limits, etc.
Specific functions of the TSX CFY modules
The functions offered by the step by step axes control modules are as follows:
-
Event processing: the events detected by the module can be used to activate an event task in the sequential program.
-
Boost command: this function allows you to boost the step by step motor during acceleration or deceleration phases.
-
Brake command: this function allows you to control the brake of the step by step motor when starting and stopping the movement.
-
Feed hold: this function allows you to stop the movement in progress momentarily.
-
Deferred pause: this function allows you to stop a machine cycle momentarily without disrupting it.
-
End of run limits: overshooting these limits triggers the stopping of the movement. Having overshot an end of run limit, only return movements between the limits are accepted.
-
External stop: activation of the external stop input causes the movement to stop.
-
Step failure input and step failure control reset output: these functions allow you, via the application, to manage step failure information originating from the translator. For the module, the activation of step failure input does not constitute a stop condition, nor an error condition.
