Test step 4
• After mains switching and an overload of the rated motor current ( C00088 ), the I²xt motor
monitoring has to be tripped faster than before mains switching with the same overload.
• From software version V11.0:
Initial value of the thermal model of the I²xt motor monitoring: C01197 > 0 %.
Example for a UL 508C-compliant total parameterisation of the I²xt motor monitoring of the device:
Code Setting Info
C00120 100 % Switch-off threshold of motor overload protection (I²xt)
C00128/2 11.8 min Thermal time constant - laminated core/housing
C01195 0 % Percentage of the winding in the final temperature
C01196/1 0 % Speed = 0 (standstill)
C01196/2 < 100 % Permissible motor torque at standstill
C01196/3 20 Hz * ( C00089 / C00087 ) Speed n
2
from which on the torque must be reduced
C01196/4 100 % Permissible motor torque at speed n
2
(torque reduction)
C01196/5 100 % Rated speed
C01196/6 100 % Permissible motor torque at rated speed
C01196/7 100 % Rated speed
C01196/8 100 % Speed above rated speed
C01197 > 0 % Initial value of the thermal model of the I²xt motor
