Function:
[0 - 65535 V] View the compressor voltage, a
calculated value used for
controlling the compressor.
Function:
[0 - 6553.5
View the compressor frequency,
without resonance damping.
Function:
[0 - 655.35
View the compressor current
measured as an average value, I
Function:
[0 -
View a 2 byte word reporting the
actual compressor frequency
(without resonance damping) as a
percentage (scale 0000-4000 hex) of
parameter 4-19 Max Output
Frequency.
Function:
[-30000 -
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.
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.
Function:
[-30000 -
View the actual motor RPM. The
motor RPM is estimated in open-
loop process or closed-loop process
control modes and the motor RPM
is measured in speed closed-loop
mode.

Function:
[0 - 100 %]
View the calculated compressor
motor temperature in percentage of
allowed maximum. At 100%, a trip
occurs, if selected in
parameter 1-90 Motor Thermal
Protection. The basis for the
calculation is the ETR function
selected in parameter 1-90 Motor
Thermal Protection.
Function:

Shows the actual torque yielded in
percentage of the rated torque,
based on the setting of the motor
size, and rated speed in
parameter 1-20 Motor Power or
parameter 1-21 Motor Power [HP]
and parameter 1-25 Motor Nominal
Speed.
This is the value monitored by the

Detection.

Function:
[0 - 255 %]
View the percentage of thermal
load on the frequency converter. At

Function:
[0 - 655.35
View the inverter nominal current.

The data is used for compressor
protection, and so on.
