Analog Outputs:

The two metering analog outputs are available at regulator board terminals 24, 25 and 26.
Terminal 25 is the common connection for both output signals. The selected signals for both
meter outputs are averaged (filtered) over 100 msec to reduce meter fluctuations.
METER OUT 1 SELECT (P.404) corresponds to terminals 24 and 25 (default: CML
FEEDBACK). METER OUT 2 SELECT (P.405) corresponds to terminals 25 and 26 (default:
SPD LOOP FEEDBACK).
Refer to Appendix B, METER OUT 1 SELECT (P.404) and METER OUT 2 SELECT (P.405)
parameters, for additional drive test points that can be configured to source Meter Outputs 1
and 2.
