Description of choice:
Normal function
[0] is used for normal operation of
the motor.
Function with de-activated inverter
[1] is selected if
control is desired over the influence of the control
signal on the control card and its functions - without
the motor shaft running.
Control card [2]
is selected if control of the analogue
and digital inputs, analogue and digital outputs, relay
outputs and the control voltage of +10 V is desired.
A test connector with internal connections is required
for this test.
The test connector for the
Control card
[2] is set up
as follows:
connect 4-16-17-18-19-27-29-32-33;
connect 5-12;
connect 39-20-55;
connect 42 - 60;
connect 45-53-54.
Use the following procedure for the control card test:
1) Select
Control card test
.
2) Cut off the mains supply and wait for the light in
the display to go out.
3) Insert the test plug (see preceding column).
4) Connect to mains.
5) The VLT frequency converter expects the [OK] key
to be pressed (the test cannot be run without
LCP).
6) The VLT frequency converter automatically tests
the control card.
7) Remove the test connector and press the [OK]
key when the VLT frequency converter displays
"TEST COMPLETED".
8) Parameter 620
Operating mode
is automatically
set to
Normal function
.
If the control card test fails, the VLT frequency
converter will display "TEST FAILED". Replace the
control card.
Initialisation
[3] is selected if the factory setting of the
unit is to be generated without resetting parameters
