[0] Normal
operation
*
[1] Control

VLT
Function:
Use this parameter to specify normal operation,
to perform tests, or to initialize all parameters
except:
•
Parameter 15-03 Power Up's.
•
Parameter 15-04 Over Temp's.
•
Parameter 15-05 Over Volt's.
This function is active only when the power is
cycled (power off/power on) to the frequency
converter.
Normal operation of the frequency converter
with the motor in the selected application.
Tests the analog and digital inputs and outputs
and the +10 V control voltage. The test requires
a test connector with internal connections.
Use the following procedure for the control card
test:
1. Select [1] Control card test.
2. Disconnect the mains supply and wait
for the light in the display to go out.
3. Set switches S201 (A53) and S202
(A54)=ON/I.
4. Insert the test plug (see
Illustration 3.54).
5. Connect to mains supply.
6. Carry out various tests.
7. The results are shown in the display
and the frequency converter moves
into an infinite loop.
8. Parameter 14-22 Operation Mode is
automatically set to [0] Normal
operation. Carry out a power cycle to
start up in normal operation after a
control card test.
If the test is OK
LCP readout: Control card OK.
Disconnect the mains supply and remove the
test plug. The green LED on the control card
lights up.
If the test fails
LCP readout: Control card I/O failure.
Replace the frequency converter or control card.
The red indicator light on the control card is
turned on. To test the plugs, connect/group the
following terminals as shown in Illustration 3.54:
•
(18, 27, and 32)
•
(19, 29, and 33)
•
(42, 53, and 54)

Illustration 3.54 Wiring Control Card Test
Resets all parameter values to default settings
except:
•
Parameter 15-03 Power Up's.
•
Parameter 15-04 Over Temp's.
•
Parameter 15-05 Over Volt's.
The frequency converter resets during the next
power-up.
Parameter 14-22 Operation Mode also reverts to
the default setting [0] Normal operation.
Function:
Enter the current limit trip delay in s. When the
output current reaches the current limit
(parameter 4-18 Current Limit), a warning is
triggered. When the current limit warning has
been continuously present for the period specified
in this parameter, the frequency converter trips. To
run continuously in current limit without tripping,
set the parameter to 60 s. Thermal monitoring of
the frequency converter remains active.
