VLT
®
FCD Series
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 fre-
quency 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 percent-
age (sum of analogue/pulse/serial communication) in
the range from Minimum reference, Ref
MIN
to Maxi-
mum 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.
Inverter temperature, parameter 537:
Gives the present inverter temperature on the fre-
quency 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
converter in Hex. See Serial communication for the
FCD 300.
Warning word, parameter 540:
States whether there is a warning on the frequency
converter in Hex. See Warning word, extended sta-
tus 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
restarted.
Pulse input 29[Hz], parameter 545:
Gives a pulse frequency in Hz connected to terminal
29.
✭ = factory setting. () = display text [] = value for use in communication via serial communication port
