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 |
| 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 |
| FieldbusA Fieldbus is an industrial network system for real-time distributed control (e.g. CAN or Profibus). It is a way of connecting instruments in a plant design | Index/Subindex | Object Start Version | |

Description
Use this keyword to set the position value for a Compare setpoint. This position value will be compared against a Compare source (CMPx.SOURCE on pg. 1). If they match, an output pulse is generated. A setpoint also requires a width (CMPx.WIDTH on pg. 1) and width type (CMPx.WIDTHTYPE on pg. 1).
A setpoint must be armed (CMPx.ARM on pg. 1) 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
