Description of choice:
Resulting reference %, parameter 515:
Gives the resulting reference as a percentage in the
range from Minimum reference, Ref
MIN
to Maximum
reference, Ref
MAX
. See also Dealing with references.
Resulting reference [unit], parameter 516:
Gives the resulting reference in Hz in Open loop (pa-
rameter 100). In a closed loop the reference unit is
selected in parameter 416 Process units.
Feedback [unit], parameter 517:
Gives the resulting feedback value with the unit/scal-
ing selected in parameters 414, 415 and 416. See also
dealing with feedback.
Frequency [Hz], parameter 518:
Gives the output frequency from the frequency con-
verter.
Frequency x scaling [-], parameter 519:
corresponds to the present output frequency f
M
multi-
plied by the factor preset in parameter 008 Display
scaling of output frequency .
Motor current [A], parameter 520:
Gives the motor's phase current measured as an ef-
fective value.
Torque [Nm], parameter 521:
Gives the motor's present load in relation to the motor's
rated torque.
Power [kW], parameter 522:
Gives the present power absorbed by the motor in kW.
Power [HP], parameter 523:
Gives the present power absorbed by the motor in HP.
Motor voltage, parameter 524:
Gives the voltage being supplied to the motor.
DC link voltage, parameter 525:
Gives the intermediate circuit voltage in the frequency
converter.
Thermal load, motor [%], parameter 526:
Gives the calculated/estimated thermal load on the
motor. 100% is the cut-out limit. See also parameter
128 Thermal motor protection.
Thermal load INV [%], parameter 527:
Gives the calculated/estimated thermal load on the
frequency converter. 100% is the cut-out limit.
Digital input, parameter 528:
Gives the signal status from the 5 digital inputs (18, 19,
27, 29 and 33). Input 18 corresponds to the bit on the
extreme left. '0' = no signal, '1' = connected signal.
Terminal 53 analogue input [V], parameter 529:
Gives the voltage value for the signal on terminal 53.
Terminal 60 analogue input [mA], parameter 531:
Gives the present value for the signal on terminal 60.
Pulse reference [Hz], parameter 532:
Gives a pulse frequency in Hz connected to terminal
33.
External reference, parameter 533:
Gives the sum of external references as a percentage
(sum of analogue/pulse/serial communication) in the
range from Minimum reference, Ref
MIN
to Maximum
reference, Ref
MAX
.
Status word, parameter 534:
Gives the present status word for the frequency con-
verter in Hex. See Serial communication for the VLT
2800.
Bus feedback 1, parameter 535:
Allows writing of a bus feedback value which will then
form part of the feedback handling.
Inverter temperature, parameter 537:
Gives the present inverter temperature on the frequen-
cy converter. The cut-out limit is 90-100 °C, with cut
back in at 70 ± 5 °C.
Alarm word, parameter 538:
Gives in Hex code which alarm is on the frequency
converter. See Warning word, extended status word
and alarm word.
Control word, parameter 539:
Gives the present control word on the frequency con-
verter in Hex. See Serial communication for the VLT
2800.
Warning word, parameter 540:
States whether there is a warning on the frequency
converter in Hex. See Warning word, extended status
word and alarm word.
Extended status word, parameter 541:
States whether there is a warning on the frequency
converter in Hex code. See Warning word, extended
status word and alarm word.
Pulse count, parameter 544:
This parameter can be read out via the LCP display
(009-012). When you run with counter stop, this pa-
rameter enables you, either with or without reset, to
read the number of pulses registered by the device.
The highest frequency is 67.6 kHz, while the lowest is
5 Hz. The counter is reset when counter stop is re-
started.
= factory setting, () = display text, [] = value for use in communication via serial communication port
