Normal connection with one common DC motor:
This high voltage measurement circuit is performed by galvanic
isolation devices (see
Figure 4/4).
The correct EMF feedback is selected by the parameter
ADJ UDC
(47.10) = [0,5].

Note: The input for the armature overvoltage protection
(28.22) and
rated motor voltage
(99.02) are at 50 % of the actual armature
voltage value!
Example: Supply voltage = 600 V
(99.02) = [650 V]
Rated motor voltage = 1300 V
(28.22) = [125 %]
⇒ 1500 V
