message "external fault" on the display when the
selected terminal is logic "0". The alarm message will
also be active via digital outputs 42/45 and relay outputs
01/04 if programmed for Safety interlock. The alarm
can be reset using a digital input or the [OFF/STOP] key.
Data change lock is selected if data changes
to parameters are not to be made via the control

Function:
This parameter allows a choice of the desired
option on terminal 53.
Scaling of the input signal is effected in
parameters 309 and 310.
Description of choice:
No operation. Is selected if the frequency converter is
not to react to signals connected to the terminal.
Reference. Is selected to enable change of reference
by means of an analogue reference signal.
If other inputs are connected, these are added
up, taking account of their signs.
Feedback-signal. Is selected if closed loop control
with an analogue signal is used.
Torque limit. Is used if the torque limit value
set in parameter 221 is to be changed by
means of an analogue signal.
Thermistor. Is selected if a thermistor integrated in the
motor is to be able to stop the frequency converter
in case of motor overtemperature. The cut-out value
is > 3 k . The thermistor is connected to terminal
50 and the actual input selected (53 or 54).
NB!:
If the temperature of the motor is utilized
through a thermistor via the frequency converter,
the following most be noted:
In case of short circuits between motorwinding
and thermistor, PELV is not complied with.
In order to comply with PELV, the thermistor
must be utilized externally.

If a motor features a thermal switch instead, this
can also be connected to the input. If motors run
in parallel, the thermistors/thermal switches can
be connected in series (total resistance < 3 k ).
Parameter 128 must be programmed for Thermistor
warning [1] or Thermistor trip [2].
Relative reference is selected if a relative adjustment
of the reference sum is required.
This function is only active if Relative has been selected
(parameter 214). The relative reference on terminal
54/60 is a percentage of the full range of the terminal
in question. This will be added to the sum of the other
references. If several relative references have been
selected (preset reference 215-218, 311 and 314),
these will be added first, following which this sum will
be added to the sum of the active references.
