CMPx.SETPOINT

Description

Use this keyword to set the position value for a Compare setpointSetpoint is the target value that an automatic control system, for example PID controller, will aim to reach. This position value will be compared against a Compare source (CMPx.SOURCE). If they match, an output pulse is generated. A setpoint also requires a width (CMPx.WIDTH) and width type (CMPx.WIDTHTYPE).

A setpoint must be armed (CMPx.ARM) before it is active. If a setpoints value, width, or width type are changed after it has been armed, that setpoint will be automatically disarmed.

Example

The following example sets the value of setpoint 1 to one billion for CMP1.

-->CMP1.SETPOINT 1 1000000000

Hardware Supported

Compare functionality is supported on hardware revisions D, DB, DA, and higher depending on the drive type. Check the label on the side of the drive to ensure the AKD meets one of the following requirements.

AKD Type	Hardware Revision Supported
AKD	Revision D or higher
AKD PDMM	Revision DB or higher
AKD-T-IC"Integrated Circuits" Miniaturized electronic circuits (consisting mainly of semiconductor devices, as well as passive components) that have been manufactured in the surface of a thin substrate of semiconductor material	Revision DA or higher

Variants Supported
