CMPx.SOURCE

Description

Setpoints (CMPx.SETPOINT) are compared against Compare source values. The setpoint Setpoint is the target value that an automatic control system, for example PID controller, will aim to reach must be armed (CMPx.ARM) for it to be compared against a source. If they match, an output pulse is generated.

Value	Compare Source
0	Feedback 1 (FB1)
1	Feedback 2 (FB2)
2	Feedback 3 (FB3)
3	Position Loop Feedback (PL.FB )

The source must be set before CMPx.SETPOINT.

Example

The following example sets the source to PL.FB for CMP0.

-->CMP0.SOURCE 3

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
