Shows the actual position error in
position units defined in parameter
group 17-7* Position Scaling. Position
error is the difference between the
actual position and the
commanded position. The position
error is the input for the position PI
controller.

3.16.2 16-1* Motor Status
16-10 Power [kW]
Range: Function:
0 kW [0 - 10000 Shows motor power in kW. The
*
kW] value shown is calculated based on
the actual motor voltage and motor
current. The value is filtered, and
therefore approximately 1.3 s may
pass from when an input value
changes to when the data readout
values change. The resolution of
readout value on fieldbus is in
10 W steps.
16-11 Power [hp]
Range: Function:
0 hp [0 - 10000 View the motor power in hp. The
*
hp] value shown is calculated based on
the actual motor voltage and motor
current. The value is filtered, and
therefore approximately 1.3 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 - 6000 V] View the motor voltage, a
*
calculated value used for
controlling the motor.

Function:
[0 - 6500 Hz] View the motor frequency without
resonance damping.
Function:
[0 - 10000 A] View the motor current measured
as an average value, I
is filtered, and thus approximately
1.3 s may pass from when an input
value changes to when the data
readout values change.
Function:
[-100 - View a 2-byte word reporting the
100 %] actual motor frequency (without
resonance damping) as a
percentage (scale 0000–4000 hex)
of parameter 4-19 Max Output
Frequency. Set parameter 9-16 PCD
Read Configuration index 1 to send
it with the status word instead of
the MAV.
Function:
[-3000 - 3000 View the torque value with sign,
Nm] 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. In flux control
principle, this readout is
compensated for in
parameter 1-68 Motor Inertia for
improved accuracy.
Function:
[-30000 - View the actual motor RPM. In
30000 RPM] open-loop or closed-loop process
control, the motor RPM is
estimated. In speed closed-loop
modes, the motor RPM is measured.
