Start-up with low voltage stator 45
Time setting
Set rotor-side converter 16.01
PARAM LOCK to OFF.
Set the date and time as follows:
• Set parameter 95.07 RTC MODE value to SET.
• Check/adjust the date and time by parameters 95.01…95.06.
• Set parameter 95.07 RTC MODE value to SHOW.
16.01 PARAM LOCK
95.07 RTC MODE
95.01…95.06
Digital inputs
Check that all digital inputs are connected properly.
01.15 DI STATUS
Grid-side converter and crowbar test
Communication between the grid-side converter and the rotor-side converter is checked by controlling the
grid-side converter unit via the rotor-side converter unit parameters.
Set parameter 21.01 ISU LOCAL CTR WORD to 9 (hex), ie, 1001
(bin): Grid-side converter starts charging the DC capacitors, closes
the main contactor and starts modulating.
21.01 ISU LOCAL CTR
WORD
Check the grid-side converter status.
Note
: Only the three least
significant bits are relevant in this case.
231H (1000110
001
bin) before the grid-side converter is started
737H (11100110
111
bin) when the grid-side converter is running
238H (1000111
000
bin) when the grid-side converter has tripped on a
fault.
05.10 ISU STATUS WORD
Check that the DC link is charged.
01.10 DC VOLTAGE
Check that the Voltage and Current Measurement Unit NUIM-6x
functions, ie, the grid frequency is positive and the grid voltage is
correct.
01.05 NET FREQUENCY
01.11 MAINS VOLTAGE
Stop the grid-side converter by setting parameter 21.01 ISU LOCAL
CTR WORD to 0 (hex).
21.01 ISU LOCAL CTR
WORD
Check the functioning of the crowbar by starting and stopping the
grid-side converter. (Parameter 21.01 ISU LOCAL CTR WORD
setting 9 (hex) = START and 0 (hex) = STOP)
When DC voltage is 0 V, 01.15 DI STATUS bit 4 value must be 0
(ie, crowbar inactive). 01.15 DI STATUS = 1303 (hex)
When DC voltage exceeds 100 V, 01.15 DI STATUS bit 4 value must
be 1 (ie, crowbar active). 01.15 DI STATUS = 1713 (hex)
01.15 DI STATUS
If the converter is NOT equipped with an active crowbar, continue to the next section.
Activate the active crowbar by setting rotor-side converter parameter
31.01 CROWBAR HW TYPE according to the type of active crowbar
in use.
Note:
If the converter is equipped with an active crowbar, it must
always be activated by parameter 31.01 even when low voltage ride
through (LVRT) and / or grid support is not used.
31.01 CROWBAR HW
TYPE
Start the grid-side converter by setting parameter 21.01 ISU LOCAL
CTR WORD to 9 (hex).
21.01 ISU LOCAL CTR
WORD
Check the communication between the rotor-side converter and the
active crowbar:
The communication is OK if the temperature of the crowbar is about
25…40 °C and the converter does not trip for crowbar communication
time-out.
