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 initialise all parameters
except parameter 15-03 Power Up's,
parameter 15-04 Over Temp's and
parameter 15-05 Over Volt's. This function is
active only when the power is cycled to the
frequency converter.
Select [0] Normal operation for normal
operation of the frequency converter with the
motor in the selected application.
Select [1] Control card test to test 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 indicator light in the display to
go out.
3. Set switches S201 (A53) and S202
(A54) to ON/I.
4. Insert the test plug (see
Illustration 3.61).
5. Connect to mains supply.
6. Carry out various tests.
7. The results are showed on the LCP
and the frequency converter moves
into an infinite loop.
8. Parameter 14-22 Operation Mode is
automatically set to 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 indicator light 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. Test plugs (connect the following

Select [2] Initialisation to reset all parameter
values to default settings, except for:
Parameter 15-03 Power Up's,
parameter 15-04 Over Temp's, and
parameter 15-05 Over Volt's. The frequency
converter resets during the next power-up.
Parameter 14-22 Operation Mode also returns to
the default setting [0] Normal operation.
Remember to set switches S201 (A53) and S202
(A54) as specified in the parameter description
when performing a control card test.
Otherwise, the test fails.
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.
Function:
Enter the torque limit trip delay in s. When the
output torque reaches the torque limits
