Parameter Description
NOTICE
The motor may start without warning. If the specified
number of automatic resets is reached within 10
minutes, the frequency converter enters [0] Manual reset
mode. After the manual reset is performed, the setting

of parameter 14-20 Reset Mode reverts to the original
option. If the number of automatic resets is not reached
within 10 minutes, or when a manual reset is performed,
the internal automatic reset counter returns to 0.

Function:
Enter the time interval from trip to start of the
automatic reset function. This parameter is
active when parameter 14-20 Reset Mode is set
to [1]–[13] Automatic reset.
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 3.41).
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

except for:
•
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.
Select this option to reset all parameters
(including bus and motor parameters) to
default values.
