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. 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 following terminals to each other): 18 - 27 - 32; 19 - 29 - 33; 42 - 53 - 54
Initialization
Select [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
Function:
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 continuously present for the period speci-
fied in this parameter, the frequency converter trips. Disable the trip delay by setting the parameter to 60 s =
OFF. Thermal monitoring of the frequency converter will still remain active.
Function:
When the frequency converter detects an over-voltage in the set time trip will be effected after the set time.
