NOTE
When the [OK] key is activated the
parameter is reset to zero.
620 Operation Mode
(OPERATION MODE)
Value:
Normal operation (NORMAL OPERATION)
Control card test (CONTROL CARD TEST)
Initialize (INITIALIZE)
Function:
In addition to its normal function, this parameter
can be used to test the control card.
There is also the opportunity to perform an
initialization at the factory setting for all parameters
in all Setups, with the exception of parameters
500 Address, 501 Baudrate, 600-605 Operating
data and 615-617 Fault log.
Description of choice:
Normal function [0] is used for normal
operation of the motor.
Control card test [2] is selected if you wish to check
the control card's analog/digital inputs, analog/digital
outputs, relay outputs and 10 V and 24 V voltages.
The test is performed as follows:
18 - 19 - 27 - 29 - 33 - 46 are connected.
20 - 55 are connected.
42 - 60 are connected.
01 - 50 are connected.
02 - 53 are connected.
03 - 31B are connected.
Use the following procedure for the control card test:
1. Select control card test.
2. Disconnect the AC line voltage and wait until the
light in the display has disappeared.
3. Mount according to drawing and description.
4. Connect the AC line voltage.
5. The variable frequency drive automatically
undertakes a test of the control card.

Decentral Solutions
If the LEDs are flashing a code (4 LEDs alternatively),
the control card test has failed (see the section Internal
faults for further details. Change the control card
to start up the variable frequency drive.
If the variable frequency drive comes into
Normal/Display mode, the test is OK. Remove the
test connector and the variable frequency drive is
ready for operation. Parameter 620 Operating mode
is automatically set to Normal operation [0].

Initialization [3] is selected if you wish to use
[2]
the unit's factory setting.
[3]
Procedure for initialization:
1. Select Initialization [3].
2. Disconnect the AC line voltage and wait until the
light in the display has disappeared.
3. Connect the AC line voltage.
4. An initialization is performed in all parameters
in all Setups, with the exception of parameters
500 Address, 501 Baudrate, 600-605 Operating
data and 615-617 Fault log.
