16-16 Torque [Nm]
Range: Function:
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 read-out 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
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* 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:
0.0 %* [-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:
0.0
Nm*
[-200000000.0 -
200000000.0
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 will depend on
the max. motor current as well as the
16-25 Torque [Nm] High
Range: Function:
motor used. This specific readout has
been adapted to be able to show
higher values than the standard
readout in 16-16 Torque [Nm].
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 an 30 ms time constant.
16-32 Brake Energy /s
Range: Function:
0.000 kW* [0.000 - 10000.000
kW]
View the brake power
transmitted to an external brake
resistor, stated as an instan-
taneous value.
16-33 Brake Energy /2 min
Range: Function:
0.000 kW* [0.000 -
10000.000 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 ±5 °C,
and the motor cuts back in at 60 ±5 °C.
16-35 Inverter Thermal
Range: Function:
0 %* [0 - 100 %] View the percentage load on the inverter.
16-36 Inv. Nom. Current
Range: Function:
Size related* [0.01 -
10000.00 A]
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.
16-37 Inv. Max. Current
Range: Function:
Size related* [0.01 -
10000.00 A]
View the inverter maximum
current, which should match the
nameplate data on the connected
