16-16 Torque [Nm]
Range:
Function:
0
Nm
*
[-3000
- 3000
Nm]
View the torque value with sign, applied to the
motor shaft. Linearity is not exact between
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 depend on the max.
motor current as well as the motor used. The
value is filtered, and thus approx. 30 ms may
pass from when an input changes value to
when the data readout values change.
16-17 Speed [RPM]
Range:
Function:
0 RPM
*
[-30000 -
30000 RPM]
View the actual motor RPM. In open loop
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
parameter 1-90 Motor Thermal Protection
.
16-19 KTY sensor temperature
Range:
Function:
0 °C
*
[0 - 0 °C] Returning the actual temperature on KTY
sensor built into the motor.
See parameter group
1-9* Motor Temperature
.
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 %
*
[-200 - 200 %] 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:
0 Nm
*
[-200000000 -
200000000
Nm]
View the torque value with sign, applied
to the motor shaft. Some motors supply
more than 160% torque. Consequently,
the min. value and the max. value
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
6.13.2 16-3* Drive Status
16-30 DC Link Voltage
Range:
Function:
0 V
*
[0 - 10000 V] View a measured value. The value is filtered
with a 30 ms time constant.
16-32 Brake Energy /s
Range:
Function:
0 kW
*
[0 - 10000 kW] View the brake power transmitted to an
external brake resistor, stated as an
instantaneous value.
16-33 Brake Energy /2 min
Range:
Function:
0 kW
*
[0 - 10000
kW]
View the brake power transmitted to an
external brake resistor. The mean power
is calculated on an average basis for the
most recent 120 s.
16-34 Heatsink Temp.
Range:
Function:
0 °C
*
[0 -
255 °C]
View the frequency converter heatsink
temperature. The cut-out limit is 90

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:
Function:

*
[0.01 -
10000 A]
View the inverter nominal current,
which must match the nameplate
data on the connected motor. The
data are used for calculation of
torque, motor protection, etc.
