Parameter Descriptions
DR-16 Torque [Nm]
Range: Function:
0 [-3000 View the torque value with sign, applied to the
Nm - 3000 motor shaft. Linearity is not exact between
*
Nm] 160% motor current and torque in relation to
the rated torque. Some motors supply more
than 160% torque. Therefore, the minimum
value and the maximum value depend on the
maximum motor current and the motor used.
The value is filtered, and thus approximately 30
ms may pass from when an input changes
value to when the data readout values change.
In flux control principle, this readout is
compensated for inparameter H-88 Motor Inertia
for improved accuracy.
DR-17 Speed [RPM]
Range: Function:
0 RPM [-30000 - View the actual motor RPM. In open
*
30000 RPM] loop or closed loop process control, the
motor RPM is estimated. In speed closed-
loop modes, the motor RPM is measured.
DR-18 Motor Thermal
Range: Function:
0 % [0 - View the calculated thermal load on the motor.
*
100 %] The cut-out limit is 100%. The basis for
calculation is the Electronic Thermal Overload
function selected in parameter F-10 Electronic
Overload.
DR-19 KTY sensor temperature
Range: Function:
0 °C [0 - 0 °C] Returning the actual temperature on KTY
*
sensor built into the motor.
See parameter group chapter 3.7.9 H-9# Motor
Temperature.
DR-20 Motor Angle
Range: Function:
0 [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).
DR-21 Torque [%] High Res.
Range: Function:
0 % [-200 - 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 - 200 %] Value shown is the torque in percent of
nominal torque, with sign, applied to the
motor shaft.
Function:
[0 - 10000 kW] Readout of the mechanical power
applied to the motor shaft.
[0.0000 - 100.0000
*
Ohm]
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 DR-16 Torque [Nm].
Function:
with a 30 ms time constant.
Function:
[0 - 10000 kW] View the brake power transmitted to an
external brake resistor, stated as an
instant value.
Function:
[0 - View the brake power transmitted to an
external brake resistor. The mean power is
calculated on an average level based on the
selected time period within
parameter B-13 Braking Thermal Overload.
