Programming
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 thermal
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
4 4
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 terminal
60.
Pulse reference [Hz] gives the reference in Hz connected to
terminal 33.
External reference [%] gives the sum of external references
as a percentage (sum of analog/pulse/serial communi-
cation) in the range from Minimum reference, Ref
Maximum reference, Ref
Status word [Hex] gives one or several status conditions in
a hex code. See chapter 4.7 Serial communication for
further information.
Heat sink temp.[°C] gives the present heat sink temperature
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 chapter 4.7 Serial communication for further
information.
Control word [Hex] gives the control word for the frequency
converter. See chapter 4.8 Serial Communication Parameters
for further information.
Warning word [Hex] gives one or several warnings in hex
code. See chapter 4.8 Serial Communication Parameters for
further information.
Extended status word [Hex] gives one or several status
modes in hex code. See chapter 4.7 Serial communication
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 installed.
If there are no communication options, 0 hex is displayed.
Pulse count gives the number of pulses that the unit has
registered.
Power [W] gives the present power that the motor is
absorbing in W.
010 Small display line 1.1
Value:
See par. 009 Large display
readout
Function:
In this parameter, the first of 3 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. Press [Display Status] to activate the
display readout.
Description of choice:
See parameter 009 Large display readout.
011 Small display readout 1.2
Value:
See parameter 009 Large display
readout
Function:
See the functional description given in parameter 010 Small
display readout.
Description of choice:
See parameter 009 Large display readout.
012 Small display readout 1.3
Value:
See parameter 009 Large display
readout
Function:
See the functional description given under parameter 010
Small display readout.
Description of choice:
See parameter 009 Large display readout.
013 Local control
Value:
Local not active (DISABLE)
Local control and open loop without slip compen-
sation
(LOC CTRL/OPEN LOOP)
Remote-operated control and open loop without
slip compensation
(LOC+DIG CTRL)
Local control as parameter 100 Configuration
(LOC CTRL/AS P100)
Remote-operated control as parameter 100 Config-
uration
(LOC+DIG CTRL/AS P100)
Function:
This is where the required function is selected if [1] Local
operation has been selected in Parameter 002.
Description of choice:
If [0] Local not active is selected, it is not possible to set a
reference via parameter 003 Local reference.
To enable a shift to [0] Local not active, set parameter 002
Local/remote operation to [0] Remote operation.
Select [1] Local control and open loop if the motor speed is
to be set via parameter 003 Local reference. When this
selection is made, parameter 100 Configuration automat-
ically shifts to [0] Speed regulation, open loop.
[2] Remote-operated control and open loop functions in the
same way as [1] Local control and open loop; however, the
