Parameter Function
r0025 CO: Actual output
voltage [V]
Displays filtered [rms] voltage applied to motor. This value is available filtered (r0025) and unfiltered
(r0072).
r0026[0] CO: Actual filtered
DC-link voltage [V]
Displays filtered DC-link voltage. This value is available filtered (r0026) and unfiltered (r0070).
Index: [0]
Note: r0026[0] = Main DC-link voltage
r0027 CO: Actual output
current [A]
Displays rms value of motor current. This value is available filtered (r0027) and unfiltered (r0068).
r0028 CO: Motor current
modulus
Displays estimated rms value of motor current calculated from dclink current.
r0031 CO: Actual filtered
torque [Nm]
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
Displays (mechanical) shaft power. Value is displayed in [kW] or [hp] depending on setting for P0100 (op-
eration 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]
Displays calculated motor temperature.
r0036 CO: Converter over-
load utilization [%]
Displays converter overload utilization calculated via the I
The actual I
If the current exceeds the threshold for P0294 (converter I
I t) is generated and the output current of the converter reduced via P0290 (converter overload reaction).
2
If 100 % utilization is exceeded, fault F5 (converter I
r0037[0...1] CO: Converter tem-
perature [°C]
Displays measured heat sink temperature and calculated junction temperature of IGBTs based on thermal
model.
Index: [0]
[1]
Note: The values are updated every 128 ms.
