Frequency [Hz]
gives the output frequency of the fre-
quency converter.
Output frequency x scaling [-]
equals the present output
frequency f
M
multiplied by the factor set in parameter
008
Display scaling of output frequency
.
Motor current [A]
gives the phase current of the motor
measured as an effective value.
Torque [%]
denotes the motor's present load in relation
to the motor's rated torque.
Power [kW]
gives the present power that the motor is
absorbing in kW.
Power [HP]
gives the present power that the motor is
absorbing in HP.
Motor voltage[V]
gives the voltage supplied to the mo-
tor.
DC link voltage [V]
gives the intermediate circuit voltage
of the frequency converter.
Thermal load motor [%]
gives the calculated/estimated
load on the motor. 100 % is the cut-out limit.
Thermal load [%]
gives the calculated/estimated ther-
mal load on the frequency converter. 100 % is the cut-
out limit.
Running hours [Hours]
gives the number of hours that
the motor has tun since the last reset in parameter 619
Reset of running hours counter
.
Digital input [Binary code]
gives the signal status from
the 5 digital inputs (18, 19, 27, 29 and 33). Terminal
18 corresponds to the bit on the extreme left. `0' = no
signal, `1' = signal connected.
Analog input 53 [V]
gives the voltage value of terminal
53.
Analog input 60 [mA]
gives the present value of termi-
nal 60.
Pulse reference [Hz]
gives the reference in Hz connec-
ted to terminal 33.
External reference [%]
gives the sum of external refer-
ences as a percentage (sum of analogue/pulse/serial
communication) in the range from Minimum reference,
Ref
MIN
to Maximum reference, Ref
MAX
.
Status word [Hex]
gives one or several status condi-
tions in a Hex code. See
Serial communication
in the
VLT 2800 Design Guide
for further information.
Heatsink temp.[°C]
gives the present heatsink temper-
ature of the frequency converter. The cut-out limit is
90-100°C, while cutting back in occurs at 70 ± 5°C.
Alarm word [Hex]
gives one or several alarms in hex
code. See
Serial communication
in the
VLT 2800 De-
sign Guide
for further information.
Control word [Hex]
gives the control word for the fre-
quency converter. See
Serial communication
in the
VLT 2800 Design Guide
for further information.
Warning word [Hex]
gives one or several warnings in
hex code. See
Serial communication
in the
VLT 2800
Design Guide
for further information.
Extended status word [Hex]
gives one or several status
modes in Hex code. See
Serial communication
in the
VLT 2800 Design Guide
for further information.
Communication option card warning [Hex]
gives a
warning word if there is a fault in the communication
bus. Only active if communication options are instal-
led.
If there are no communication options 0 Hex is dis-
played.
Pulse count
gives the number of pulses that the unit
has registered.

Analog input 53 [V]
[17]
Function:
In this parameter, the first of three data values can be
selected that is to be displayed in the LCP control unit
display, line 1, position 1. This is a useful function, e.g.
when setting the PID regulator, as it gives a view of
process reactions to reference changes. The display
