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
