Parameter Description
P123* Function parameter for entering the stator reactance of a
Stator React connected induction motor. The value to be entered
corresponds to the stator reactance of a winding phase at
123 40% of the rated motor current. The parameter value is
calculated during the automatic calculation of derived
motor data (P115).
P124* Function parameter for entering the rotor time constant of
Rotor TimeConst a connected induction motor. The parameter value is
calculated during the automatic calculation of derived
124 motor data (P115).
P127 Parameter is not used.
R(Rot)Corr'nTmp

P128* Function parameter for entering the maximum current
Max Current (r.m.s. value of the fundamental component). The output
current is limited to the value entered. The limitation of the
128 output current serves to protect the connected motor.
The maximum current that can be input is limited by
converter current parameter P072. Any derating that may
be necessary because of increased pulse frequency is not
taken into account until r129.

r129 Visualization parameter for displaying the actually
I(max,set) effective maximum current (r.m.s. value of the
fundamental component). If utilization of the converter or
129 inverter exceeds 100 % (i2t calculation) or if the maximum-
current limit has been reduced, the displayed value
deviates from the value set in P128. The maximum
current can be reduced, for example, by operation at a
pulse frequency (P340, P357) > 3kHz.
