If the current limit safety function of the overload monitoring PU temperature model has
responded, the maximum current of the drive
Z19.6– is limited to the max. PU instanta-
neous value of continuous current >175.7<. See ZOverload monitoring of the power
unit– from page 723.
175.8 PU I2t max. continuous current actual value
From controller version V01.09 onwards.
The parameter displays the instantaneous value of the maximum accepted continuous
current of the conductors and capacitors.
Important for devices, which support the PU temperature model (see status PU tempera-
ture model Z175.2–).
The parameter is generated from the nominal current 2 kHz (Z129.12–), whereat the fol-
lowing correction factors are considered, which are described in "Operating conditions"
of the operating manual of the device.
m Correction factor of the device's control cabinet temperature (ambient temperature
or surface temperature). The required temperature can be entered in parameter
Z175.3–.
m Correction factor of installation altitude. The required installation altitude can be en-
tered in parameter Z175.4–.
The parameter displays the scaling factor of the I
2
t-sub-model (part of the PU tempera-
ture model).See ZOverload monitoring of the power unit– from page 723.
