CMPx.SOURCE

Description

Setpoints (CMPx.SETPOINT) are compared against Compare source values. The setpoint 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.
