4.16 Parameters: 16-** Data Readouts

16-00 Control Word
Range: Function:
0 [0 - 65535 ] View the control word sent from the frequency
*
converter via the serial communication port in
hex code.
16-01 Reference [Unit]
Range:
0 ReferenceFeed- [-4999 - 4999
backUnit ReferenceFeed-
*
backUnit]
16-02 Reference [%]
Range: Function:
0 % [-200 - View the total reference. The total reference
*
200 %] is the sum of digital, analog, preset, bus,
and freeze references, plus catch up and
slow down.
16-03 Status Word
Range: Function:
0 [0 - 65535 ] View the status word sent from the frequency
*
converter via the serial communication port in
hex code.
16-05 Main Actual Value [%]
Range: Function:
0 % [-200 - 200 %] View the 2-byte word sent with the status
*
word to the bus master reporting the
main actual value.
16-09 Custom Readout
Range:

16-10 Power [kW]
Range: Function:
0 kW [0 - Show motor power in kW. The calculated value
*
1000 shown is based on the actual DC-link voltage
kW] and DC-Link current. The value is filtered, and
therefore approximately 128 ms may pass from
when an input value changes to when the data
readout values change. The resolution of
readout value on fieldbus is in 1 W steps.

16-11 Power [hp]
Range: Function:
0 hp [0 - View the motor power in hp. The value shown
*
1000 hp] is calculated on the basis of the actual DC-link
voltage and DC-link current. The value is
filtered, and therefore approximately 128 ms
may pass from when an input value changes
to when the data readout values change.
16-12 Motor Voltage
Range: Function:
0 V [0 - 65535 V] View the motor voltage, a calculated value
*
is used for controlling the motor.
16-13 Frequency
Range: Function:
0 Hz [0 - 6553.5 Hz] View the motor frequency, without
*
resonance dampening.
16-14 Motor current
Range: Function:
0 A [0 - 655.35 View the motor current measured as an
*
A] average value, I
approximately 30 ms may pass from when
an input value changes to when the data
readout values change.
16-15 Frequency [%]
Range: Function:
0 % [0 - View a 2-byte word reporting the actual
*
6553.5 %] motor frequency (without resonance
dampening) as a percentage (scale
0000-4000 hex) of parameter 4-19 Max
Output Frequency.
16-16 Torque [Nm]
Range: Function:
0 Nm [-30000 - View the torque value with sign, applied to
30000 Nm] the motor shaft. Some motors supply more
than 160% torque. As a result, the minimum
value and the maximum value depend on
the maximum motor current as well as the
motor used.
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.
