Parameter Descriptions
16-16 Torque [Nm]
Range: Function:
0.0 [-3000.0 - View the torque value with sign, applied to the
Nm 3000.0 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. Consequently, the min.
value and the max. value will depend on the
max. motor current as well as the motor used.
The value is filtered, and thus approx. 30ms
may pass from when an input changes value
to when the data read-out values change.
16-17 Speed [RPM]
Range: Function:
0 RPM [-30000 - View the actual motor RPM. In open loop
*
30000 RPM] or closed loop process control the motor
RPM is estimated. In speed closed loop
modes the motor RPM is measured.
16-18 Motor Thermal
Range: Function:
0 % [0 - 100 %] View the calculated thermal load on the
*
motor. The cut-out limit is 100%. The basis for
calculation is the ETR function selected in
1-90 Motor Thermal Protection.
16-19 KTY sensor temperature
Range: Function:
0 C [0 - 0 C] Returning the actual temperature on KTY sensor
*
buil into the motor.
See parameter group 1-9*.
16-20 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 0-2*pi (radians).
16-21 Torque [%] High Res.
Range: Function:
0.0 % [-200.0 - 200.0 The value shown is the torque in
*
%] percent of nominal torque, with sign
and 0.1% resolution, applied to the
motor shaft.
16-22 Torque [%]
Range: Function:
0 % [-200 - 200 %] Value shown is the torque in percent of
*
nominal torque, with sign, applied to the
motor shaft.

16-25 Torque [Nm] High
Range: Function:
[-200000000.0 - View the torque value with sign,
200000000.0 Nm] applied to the motor shaft. Some
*
motors supply more than 160% torque.
Consequently, the min. value and the
max. value will depend on the max.
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
16-16 Torque [Nm].
16-30 DC Link Voltage
Range: Function:
[0 - 10000 V] View a measured value. The value is filtered
*
with an 30ms time constant.
16-32 Brake Energy /s
Range:
[0.000 - 10000.000 View the brake power
*
kW] transmitted to an external brake
resistor, stated as an instan-
taneous value.
16-33 Brake Energy /2 min
Range: Function:
[0.000 - View the brake power transmitted
*
10000.000 kW] to an external brake resistor. The
mean power is calculated on an
average basis for the most recent
120 seconds.
16-34 Heatsink Temp.
Range: Function:
[0 - 255 C] View the frequency converter heatsink
*
temperature. The cut-out limit is 90 ± 5°C, and
the motor cuts back in at 60 ± 5°C.
16-35 Inverter Thermal
Range: Function:
[0 - 100 %] View the percentage load on the inverter.
*
16-36 Inv. Nom. Current
Range:
[0.01 -
10000.00 A]
*
Function:
Function:
View the inverter nominal
current, which should match the
nameplate data on the
connected motor. The data are
used for calculation of torque,
motor protection, etc.
