Control card test
[2] is selected if monitoring is
required of the control card analogue and digital
inputs as well as its analogue, digital and relay
outputs, and control voltage of +10 V. This test
requires the use of a test connector with internal
wiring connections.
Proceed as follows:
1) Press the stop key.
2) Insert the test connector in the plug.
3) Choose control card test from parameter 604.
4) Cut out mains and wait for the light in the display
to go out.
5) Cut mains back in.
6) Press the start key.
The test will now go through three steps, each of
which gives an OK or fault message, depending on
the result. If a fault message appears, the control card
must be replaced.
Initialisation
[3] is selected if factory setting of the unit
is required without resetting of parameters 500, 501,
600 and 602.
Procedure:
1) Select initialisation.
2) Press the "Menu" key.
3) Cut out mains and wait for the light in the display
to go out.
4) Cut mains back in.

Function:
In addition to its normal function, this parameter can
be used for 2 different tests.
Furthermore, manual initialisation of all parameters
can be carried out (except for par. 501, par. 600 and
par. 602).
Description of choice:
Normal operation
[0] is used for normal running of the
motor for the application chosen.
Operation with de-activated inverter
[1] is selected if
monitoring is required of the influence that the control
signal has on the control card and its functions
without the inverter driving the motor.
