VSD_HW_2Motors_2D2S Device Module Description

The Device Module provides a ready-to-use coding template as a pattern for a motor control function comprised of two motors and one variable speed drive (VSD). The motor control function is realized via hardwired I/O signals. Each motor can be controlled by the VSD in forward or reverse direction with two switchable preset speeds.

The Device Module VSD_HW_2Motors_2D2S is represented by a function template and consists of a global variable list (GVL), and a program. After instantiation of the Device Module, these objects are added to your project. They appear with the name which has been assigned using Add Function From Template.

The GVL provides the variables which are used to monitor and control the variable speed drive and the switching between the motors via hardwired I/O signals.

The program provides the following features:

• monitor the state of the device

• switch between the two motors

• control of one motor in manual mode (latch mode)

• control of one motor in local mode (latch mode)

• control of one motor in auto mode (jog mode)
