Siemens AG 6SE7087-6QX70 (Version AE)
SIMOVERT MASTERDRIVES
Halving of the pulse frequency for operating power sections over
250 kW can be automatically selected via parameter P357 = 1 (pulse
frequency ratio = 2:1).
If the F02 option has not been enabled (n978.2 = 0), it is not possible to
select power sections > 250 kW. This can, however, be carried out by
means of a subsequent enable.
MFLB subsequent enable F02:
6SW1700-5AD00-2XX0
To enable:
When ordering, it is imperative to specify the FID modules (product
identification number, 2x4 digit number). The FID can be read out at
parameters U976.1 and U976.2.
Save the F02 PIN in parameters U977.3 and U977.4.
You can check whether option F02 is present via the display parameter
n978.2:
n978.2 = 1 ==> Option F02 is enabled
n978.2 = 0 ==> Option F02 is blocked
By halving the pulse frequency on units from 75 kW to 250 kW it is
possible to expand the output by changing the derating (see Chapter
"Technical Data").
Higher output by a lower pulse frequency!
If the pulse frequency of Performance 2 units higher than 75 kW is set
to 2.5 kHz, the output current of MASTERDRIVES VC units is then
available to the user!
6SE7031-8EF70
75 kW unit rating Performance 2 with pulse frequency 5 kHz
Rated output current = 155 A
6SE7031-8EF70-Z-F02
75 kW Performance 2 with pulse frequency 2.5 kHz
Rated output current (MASTERDRIVES VC 90 kW unit rating = 186 A)
Comparison:
6SE7032-1EG50
90 kW unit rating standard MASTERDRIVES MC
Rated output current = 175 A
