FCD Series
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
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
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
parameter 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.
