Description

PLC Variable

A PLC variable may be assigned to each channel. Double-click (or right-click and select Map) to open the PLC Variable Selector to choose or create a variable. Alternatively you may use the PLC Variable Creation Wizard to automatically create a list of variables for mapping.

I/O Function

The AKT2G-IO-SM-Lxx stepper slices provide two digital inputs.

Normal Input: This selection configures the I/O channel as a normal input.
Limit Input: This selection configures the I/O channel as the hardware limit switch Switch limiting the traverse path of the machine. Implemented as n.c. (break) contact. A sensor, typically Hall-effect, optical, eddy current, or mechanical, which is used to sense the end of travel of a linear motion assembly. In addition to preventing over travel, it is frequently used to establish a precision reference.. The drive In electrical engineering, a drive is an electronic device to provide power to a motor or servo. Control device for regulating the speed, torque and position of a motor. A unit controlling a motor using the current and timing in its coils. is disabled Removal of the ENABLE signal. Disables power stage. when a digitial input acting as a source for the hardware limit is triggered.
Brake Output: This selection configures the I/O channel as the Brake Output. This option is supported only for the second I/O channel on the terminal.

Invert Input

This option inverts the state of the input when set to True. This is set to False by default. This setting is applicable only when the I/O channel is configured as either Normal Input or Limit Input.
