:
AC + DC voltage
transducers

Special connection with two motors in series:
This high voltage measurement circuit is performed by galvanic
isolation devices (see
Figure 4/5).
The correct EMF feedback is selected by the parameter ADJ UDC
(47.10) = [1].

Note: Use for the parameters armature overvoltage protection
(28.22)
and rated motor voltage (99.02) the values of one motor!
Example: Supply voltage = 600 V
(99.02) = [650 V]
Rated motor voltage = 650 V (each)
(28.22) = [125 %]
⇒ 2 x 750 V
