Stop!
At the frequency f
d
= 0 Hz, the r.m.s. value increases to 141 % of the current
parameterised in C02773/x . As a result, the connected motor can be destroyed!
Remedy: Activation of a derating curve in i2xt monitoring or limitation of the
parameterised current in C02773/x to 71 % of the rated motor current.  Motor
