Parameter Descriptions
NOTICE
Automatic reset is also active for resetting Safe Torque
Off function in firmware version < 4.3x.
14-21 Automatic Restart Time
Range: Function:
10 s [0 - 600 s] Enter the time interval from trip to start of
*
the automatic reset function. This parameter
is active when 14-20 Reset Mode is set to [1] -
[13] Automatic reset.
NOTICE
Remember to set switches S201 (A53) and S202 (A54) as
specified below when performing a control card test in
parameter 14-22 Operation Mode [1]. Otherwise, the test
fails.
14-22 Operation Mode
Option: 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 light in the display to go
out.
3. Set switches S201 (A53) and S202
(A54) = 'ON'/I.
4. Insert the test plug (see
Illustration 3.58).
5. Connect to mains supply.
6. Carry out various tests.
7. The results are displayed 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.

Function:
If the test is OK
LCP read-out: 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 read-out: Control Card I/O failure.
Replace the frequency converter or Control
card. The red LED on the Control Card is
turned on. Test plugs (connect the following
terminals to each other): 18 - 27 - 32; 19 - 29 -

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 reverts to
the default setting [0] Normal operation.
Function:
[0 - Enter the current limit trip delay in seconds. 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,
