16-12 Motor Voltage
Range:
Function:
0 V
*
[0 - 65535 V] View the compressor voltage, a
calculated value used for
controlling the compressor.
16-13 Frequency
Range:
Function:
0 Hz
*
[0 - 6553.5
Hz]
View the compressor frequency,
without resonance damping.
16-14 Motor current
Range:
Function:
0 A
*
[0 - 655.35
A]
View the compressor current
measured as an average value, I
RMS
.
16-15 Frequency [%]
Range:
Function:
0 %
*
[0 -
6553.5 %]
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
.
16-16 Torque [Nm]
Range:
Function:
0 Nm
*
[-30000 -
30000 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.
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.
16-17 Speed [RPM]
Range:
Function:
0 RPM
*
[-30000 -
30000 RPM]
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.
16-18 Motor Thermal
Range:
Function:
0 %
*
[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
16-22 Torque [%]
Range:
Function:
0 %
*
[-200 -
200 %]
This is a readout parameter only.
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
Broken Belt Function
set in
parameter group 22-6* Broken Belt
Detection
.
3.12.3 16-3* Drive Status
16-30 DC Link Voltage
Range:
Function:
0 V
*
[0 - 65535 V] Shows the actual DC-link voltage.
16-34 Heatsink Temp.
Range:
Function:
0 °C
*
[-128 -
127 °C]
View the heat sink temperature of
the frequency converter.
16-35 Inverter Thermal
Range:
Function:
0 %
*
[0 - 255 %]
View the percentage of thermal
load on the frequency converter. At
100%, a trip occurs.
16-36 Inv. Nom. Current
Range:
Function:
0 A
*
[0 - 655.35
A]
View the inverter nominal current.
The data is used for compressor
protection, and so on.
