The ground current I is either measured directly or calculated from the conductor cur-

rents:
In addition, the following may be available:
• Θ/Θ
thermal measured value of overload protection value for stator in % of the
Trip
trip initiating overtemperature
• Θ/Θ
thermal measured value of restart inhibit (rotor winding)
LTrip
• Θ
restarting limit of restart inhibit
Restart
• T total time, before the motor can be restarted
Reclose
• Θ to Θ
temperature values at the RTD-boxes.

The power and operating values upon delivery are set such that power in line direction
is positive. Active components in line direction and inductive reactive components in
line direction are also positive. The same applies to the power factor cosϕ. It is occa-
sionally desired to define the power draw from the line (e.g. as seen from the consum-
er) positively. Parameter 1108 P,Q sign allows the signs for these componenets to
be inverted.
The calculation of the operational measured values is also performed during a fault.
The values are updated in intervals of > 0.3 s and < 1 s.
Measured values can be transferred via the interfaces to a central control and storage
unit.
