r0031 CO: Actual filtered
torque [Nm]
- - - - - Float 2
Displays electrical torque. This value is available filtered (r0031) and unfiltered (r0080).
Note: The electrical torque is not the same as the mechanical torque, which can be measured on the shaft. Due
to windage and friction a part of the electrical torque is lost in the motor.
r0032 CO: Actual filtered power - - - r2004 - Float 2
Displays (mechanical) shaft power. Value is displayed in [kW] or [hp] depending on setting for P0100
(operation for Europe / North America).
P_mech = 2 * Pi * f * M -->
r0032[kW] = (2 * Pi / 1000) * (r0022 / 60)[1 / min] * r0031[Nm]
r0032[hp] = r0032[kW] / 0.75
r0035[0...2] CO: Actual motor
temperature [°C]
- - - - DDS Float 2
Displays calculated motor temperature.
r0036 CO: Inverter overload
utilization [%]
- - - PERCEN
T
- Float 4
Displays inverter overload utilization calculated via the I
2
t model.
The actual I
2
t value relative to the maximum possible I
2
t value supplies utilization in [%].
If the current exceeds the threshold for P0294 (inverter I
2
t overload warning), warning A505 (inverter I
2
t) is
generated and the output current of the inverter reduced via P0290 (inverter overload reaction).
If 100 % utilization is exceeded, fault F5 (inverter I
2
t) is tripped.
Dependency: r0036 > 0:
If the nominal current (see r0207) of the inverter is exceeded, utilization will be displayed, otherwise, 0%
utilization is displayed.
r0037[0...1] CO: Inverter temperature
[°C]
- - - - - Float 3
Displays measured heat sink temperature and calculated junction temperature of IGBTs based on thermal
model.
Index: [0] Measured heat sink temperature
[1] Total Chip Junction Temperature
Note: The values are updated every 128 ms.
r0038 CO: Filtered power factor - - - - - Float 3
Displays the filtered power factor.
r0039 CO: Energy consumpt.
meter [kWh]
- - - - - Float 2
Displays electrical energy used by inverter since display was last reset (see P0040 - reset energy
consumption meter).
Dependency: Value is reset when P0040 = 1 (reset energy consumption meter).
P0040 Reset energy consumpt.
and energy saved meter
0 - 1 0 T - - U16 2
Resets value of r0039 (energy consumption meter) and r0043 (energy saved meter) to zero.
0 No reset
1 Reset r0039 to 0
P0042[0...1] Energy saving scaling 0.000 -
100.00
0.000 T - - Float 2
Scales the calculated energy saved value
Index: [0] Factor for kWh to currency conversion
