This video details the use of the Position Instruction with the CLICK PLUS PLC Motion outputs.
CLICK PLUS is designed to make difficult tasks a cinch and every new feature must adhere to this design principle. Adding motion control to the CLICK PLUS PLC meant that it had to be simple to configure and program. First, we created an easy-to-use interface for configuring high-speed I/O. Using this interface, it only takes three steps to turn a CLICK PLUS PLC into a 3-axis motion controller.
CLICK PLUS PLC Motion: PTO Quick Start
CLICK PLUS PLC Motion Playlist:
The Position Instruction is used to control a single axis, 2 axes, or 3 axes, and drive that axis or multiple axes to a target position. These axes have to be set up in the High-Speed I/O. To see a video on the axis configuration, please see the Quick Start video link in the description below. Here you can see the basic setup for each axis and if you need to make changes to that setup, this direct link will take you to the setup wizard. Use this drop-down menu to select which axis configuration this instruction will control. As you go through these configurations the graphic shown here will update, showing you exactly what this will control. They did a great job with these graphics to reduce the confusion. Target Position 1 is used to control Axis 1. Target Position 2 for Axis 2, and Position 3 for Axis 3. For these options, you can either enter in a tag address or enter in a direct numerical value. One thing you must be aware of is that these values may be changed while the instruction is enabled however, it requires an off-to-on transition before the updated values will be used in the instruction. For the Absolute Mode this action moves the axis to an absolute position relative to the home position ignoring the target position sign and always traveling in a positive direction. For the Incremental Mode, the axis moves to a position relative to the current position of the axis and with this option you can select this incremental move to always be in a positive, negative or in a direction controlled by the sign of the target position. The Immediate Stop Option, when enabled, specifies that the PLC should immediately stop sending pulses when disabling instructions. This will abort the move abruptly and likely lose the axis home reference. When disabled the PLC follows the specified deceleration rate if the instruction is deactivated. The axis will decelerate until reaching zero velocity. This S Curve Option will help smooth the transition of the velocity change to reduce jerk and help prevent position loss due to inertia or friction loss. The values range is from 0-100%. And finally, here are the status flags for this instruction. See the help file for how these operate during the process and a full listing of the error codes can also be found in the help file.
