Function:
[0 - 100 %] View the calculated thermal load on
the motor. The cutout limit is 100%.
The basis for calculation is the ETR
function selected in
parameter 1-90 Motor Thermal
Protection.
Function:
[0 - 0 °C] Returning the actual temperature
on KTY sensor built into the motor.
See parameter group 1-9* Motor
Temperature.
Function:
[0 - 65535 ] View the current encoder/resolver
angle offset relative to the index
position. The value range of 0–
65535 corresponds to 0–2xpi
(radian).
Function:
[-200 - The value shown is the torque in
percent of nominal torque, with
sign and 0.1% resolution, applied to
the motor shaft.
Function:
[-200 - The value shown is the torque in
percent of nominal torque, with
sign, applied to the motor shaft.
Function:
[0 - 10000 Readout of the mechanical power
applied to the motor shaft.
Function:
[0.0000 - Shows the calibrated stator
resistance.
Function:
[-200000000 View the torque value with sign,
applied to the motor shaft. Some
motors supply more than 160%
torque. Therefore, the minimum

value and the maximum value
depend on the maximum motor
current as well as the motor used.
This specific readout has been
adapted to be able to show higher
values than the standard readout in
parameter 16-16 Torque [Nm].
Function:
[-180 - 180 °] Readout of deviation between
sensorless rotor angle estimation by
motor controller and real rotor
angle based on encoder reading.
The parameter is only activated if
options in parameter 1-01 Motor
Control Principle is set to [2] Flux
Sensorless and parameter 1-10 Motor
Construction is set to [1] PM, non
salient SPM or [2] PM, salient IPM.
The encoder source used for
comparison must be selected in
7-00 Speed PID Feedback Source. To
obtain an accurate reading of
parameter 16-28, the motor angle
offset must be set in
parameter 1-41 Motor Angle Offset.
Rotor detection is configured in
parameter 7-90 which is activated
using the setting in
parameter 1-70 Start Mode in Flux
with motor feedback. Parameter 7-90
Position PI Feedback Source must be
set to [0] Motor feedb.P1-02. The
encoder is then only used for
comparison while position control is
based on the estimated sensor less
position. This enables to measure
the accuracy of position control in
sensor less mode.
Function:
[0 - 10000 V] View a measured value. The value is
filtered with a 30 ms time constant.
