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.
Par. 14-22 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. Test plugs (connect the fol-
lowing terminals to each other): 18 - 27 - 32; 19 - 29 - 33; 42
- 53 - 54
Select
Initialization
[2] to reset all parameter values to default
settings, except for par. 15-03, 15-04, and 15-05. The frequency
converter will reset during the next power-up.
Par. 14-22 will also revert to the default setting
Normal opera-
tion
[0].
14-25 Trip Delay at Torque Limit
Range:
Function:
60 s
*
[0 - 60 s = OFF]
Enter the torque limit trip delay in seconds. When the output
torque reaches the torque limits (par. 4-16 and 4-17), a warning
is triggered. When the torque limit warning has been continu-
ously 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 moni-
toring will still remain active.
