VLT
Function:
Use this parameter to specify normal operation,
to perform tests or to initialise all parameters
except 15-03 Power Up's, 15-04 Over Temp's and
15-05 Over Volt's. This function is active only
when the power is cycled (power off-power on)
to the frequency converter.
Select Normal operation [0] for normal operation
of the frequency converter with the motor in
the selected application.
Select Control card test [1] 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 Control card test [1].
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 below).
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. 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 read-out: Control Card OK.
Disconnect the mains supply and remove the
test plug. The green LED on the control card
will light 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.
To test the plugs, connect/group the following
terminals as shown below: (18 - 27 - 32), (19 -
29 - 33) and (42 - 53 - 54).

Select Initialisation [2] to reset all parameter
values to default settings, except for
15-03 Power Up's, 15-04 Over Temp's and
15-05 Over Volt's. The frequency converter will
reset during the next power-up.
14-22 Operation Mode will also revert to the
default setting Normal operation [0].
Function:
Enter the torque limit trip delay in seconds.
When the output torque reaches the torque
limits (4-16 Torque Limit Motor Mode and
4-17 Torque Limit Generator Mode), a warning is
triggered. When the torque limit warning has
been continuously present for the period
specified in this parameter, the frequency
converter trips. Disable the trip delay by setting
the parameter to 60 s = OFF. Thermal frequency
converter monitoring will still remain active.
Function:
[0 - 35 s] When the frequency converter detects
an over-voltage in the set time trip will
be effected after the set time.
