CMPx.ARM
Description
Use this keyword to arm or disarm a Compare setpoint
Setpoint is the target value that an automatic control system, for example PID controller, will aim to reach. The setpoint value will only be compared against the Compare source (CMPx.SOURCE) if that setpoint is armed. If they match, an output pulse will be generated.
An error will be generated if CMPx.SOURCE, CMPx.MODBOUND1, CMPx.MODBOUND2, CMPx.WIDTH, and CMPx.MODEN are not set prior to enabling CMPx.ARM. If CMPx.SETPOINT is not set prior to enabling CMPx.ARM, the compare will trigger at the last set value, or the default value of 0 if the drive has been power cycled.
Example
The following example arms setpoint 3 for CMP1.
-->CMP1.ARM 3 1

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 |
| 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
