Function:
These parameters can be read out via the serial communication port and
the LCP display. See also parameters 009-012
Display readout
.
NB!
Parameters 515-541 can only be read out via the serial
communication port.
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 (parameter 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/scaling selected in pa-
rameters 414, 415 and 416. See also dealing with feedback.
Frequency [Hz], parameter 518:
Gives the output frequency from the frequency converter.
Frequency x scaling [-], parameter 519:
corresponds to the present output frequency f
M
multiplied 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 effective 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 input 33[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 converter in Hex. See
Serial communication for the VLT 2800.
Inverter temperature, parameter 537:
Gives the present inverter temperature on the frequency 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
Warn-
ing word, extended status word and alarm word.
Control word, parameter 539:
Gives the present control word on the frequency converter in Hex. See
Serial communication for the FCD 300.
