5.2.4. Terminal diagram of the RTD/analog module
Terminal diagrams for the machine terminals provided with an RTD/analog module
are similar to the diagrams presented in sections “Terminal diagram of REM 543”
on page 86 and “Terminal diagram of REM 545” on page 87, except for the part
illustrating the RTD/analog module (see below), which is added to the diagrams
considering the slot numbers.

5.2.5. Definition of power direction
When the overexcited generator (G) feeds the inductive load (motor M), the real and
reactive power signs are as shown in the figure below.
The connections in generator
and motor terminals are identical (as in the terminal diagram of REM 543 on
page 86). The power direction parameter (for example in function blocks UPOW_,
OPOW_, MEPE7) is set to
Reverse
in the generator terminal and to
Forward
in
the motor terminal.
