Sets load monitoring mode.
This function allows monitoring of mechanical failure of the converter train, e.g. a broken converter belt. It
can also detect conditions which cause an overload, such as a jam. P2182 -P2190 are set to the following
values when this parameter is changed from 0.
P2182 = P1080 (Fmin)
P2183 = P1082 (Fmax) * 0.8
P2184 = P1082 (Fmax)
P2185 = r0333 (rated motor torque) * 1.1
P2186 = 0
P2187 = r0333 (rated motor torque) * 1.1
P2188 = 0
P2189 = r0333 (rated motor torque) * 1.1
P2190 = r0333 (rated motor torque)/2
This is achieved by comparing the actual frequency/torque curve with a programmed envelope (see
P2182 - P2190). If the curve falls outside the envelope, a warning A952 or trip F452 is generated.

P2182[0...2]
Load monitoring threshold
frequency 1 [Hz]
0.00 - 550.00 5.00 U, T - DDS Float 3
Sets the lower frequency threshold f_1 for defining the area where the load monitoring is effective. The
frequency torque envelope is defined by 9 parameters - 3 are frequency parameters (P2182 - P2184), and
the other 6 define the low and high torque limits (P2185 - P2190) for each frequency.
Dependency:
See P2181 for calculated default value.
Note:
Below the threshold in P2182 and above the threshold in P2184, the load monitoring mode is not active.
In this case the values for normal operation with the torque limits given in P1521 and P1520 are valid.
P2183[0...2]
Load monitoring threshold
frequency 2 [Hz]
0.00 - 550.00 30.00 U, T - DDS Float 3
Sets the frequency threshold f_2 for defining the envelope in which the torque values are valid. See
P2182.
Dependency:
See P2181 for calculated default value.
P2184[0...2]
Load monitoring threshold
frequency 3 [Hz]
0.00 - 550.00 50.00 U, T - DDS Float 3
Sets the upper frequency threshold f_3 for defining the area where the load monitoring is effective. See
P2182.
Dependency:
See P2181 for calculated default value.
P2185[0...2]
Upper torque threshold 1
[Nm]
0.0 - 99999.0 Value in
r0333
U, T - DDS Float 3
Upper limit threshold value 1 for comparing actual torque.
Dependency:
This parameter is influenced by automatic calculations defined by P0340.
See P2181 for calculated default value.
Note:
The factory setting depends on rating data of Power Module and Motor.
