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 analog
and digital inputs, analog 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 line supply and wait for the light
in the display to go out.
3. Insert the test plug (see preceding column).
4. Connect to line.
5. The VLT AFD expects the [OK] key to be pressed
(the test cannot be run without LCP).
6. The VLT AFD automatically tests the control card.
7. Remove the test connector and press the [OK] key
when the VLT AFD displays "TEST COMPLETED".
8. Parameter 620
Operating mode
is automatically
set to Normal function.
If the control card test fails, the VLT AFD 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 500
