16-02 Reference [%]
Range: Function:
0.0 % [-200.0 - View the total reference. The total
*
200.0 %] reference is the sum of digital, analog,
preset, bus, and freeze references, plus
catch-up and slow-down.
16-03 Status Word

6.13.1 16-1* Motor Status
16-10 Power [kW]
Range: Function:
0.00 [0.00 - Displays motor power in kW. The value
kW 10000.00 shown is calculated on the basis of the
*
kW] actual motor voltage and motor current.
The value is filtered, and therefore approx.

on impulse or analog
basis in the unit
resulting from the
configuration selected
in 1-00 Configuration
Mode (Hz, Nm or RPM).

16-10 Power [kW]
Range: Function:
30 ms may pass from when an input value
changes to when the data read-out values
change. The resolution of read-out value
on fieldbus is in 10 W steps.
16-11 Power [hp]
Range: Function:
0.00 [0.00 - View the motor power in HP. The value
hp 10000.00 hp] shown is calculated on the basis of the
*
actual motor voltage and motor current.
The value is filtered, and therefore
approximately 30 ms may pass from
when an input value changes to when
the data read-out values change.
16-12 Motor Voltage
Range: Function:
0.0 V [0.0 - 6000.0 V] View the motor voltage, a calculated
*
value used for controlling the motor.
16-13 Frequency
Range: Function:
0.0 Hz [0.0 - 6500.0 Hz] View the motor frequency, without
*
resonance dampening.
16-14 Motor Current
Range: Function:
0.00 A [0.00 - View the motor current measured as a
*
10000.00 A] mean value, I
and thus approximately 30 ms may pass
from when an input value changes to
when the data read-out values change.
16-15 Frequency [%]
Range: Function:
0.00 [-100.00 - View a two-byte word reporting the
% 100.00 %] actual motor frequency (without
*
resonance dampening) as a percentage
(scale 0000-4000 Hex) of 4-19 Max Output
Frequency. Set 9-16 PCD Read Configu-
ration index 1 to send it with the Status
Word instead of the MAV.
16-16 Torque [Nm]
Range: Function:
0.0 [-3000.0 - View the torque value with sign, applied to
Nm 3000.0 the motor shaft. Linearity is not exact
*
Nm] between 160% motor current and torque in
relation to the rated torque. Some motors
supply more than 160% torque.
Consequently, the min. value and the max.
value will depend on the max. motor current
. The value is filtered,
