Rectifier/Regenerating Unit Operating instructions
♦ Parameterizing a unit as a 12-pulse slave (see Section 3.8.3)
Using P077 = 5 or 6, almost all settings required for the parameterization as a 12-pulse slave
can be carried
out automatically (see Chapter 4.3.9.1).
Meaning of P077 = 5 or 6:
P077= 5:
Basic setting (index i001): 12-pulse slave (all control is carried out via the master)
Reserve setting (index i002): stand-alone unit with operator control via PMU
P077= 6:
Basic setting (index i001): 12-pulse slave (all control is carried out via the master)
Reserve setting (index i002): stand-alone unit with operator control via OP1S
Note: When the reserve setting is selected, the unit operates as a stand-alone unit with on-site operator
control. Changeover between the basic and reserve settings takes place via binary input 5 (P590=1005), but
the reserve setting can be set permanently via P590= 1.
Procedure for carrying out the P077-dependent factory setting (see Section 4.3.9.1):
• Set P051= 3 (expert mode)
• Set P052= 2 (Select "Initialize" function (set MLFB), so that P077 can be modified)
• Set P077= 5 or 6 (Select the required P077-dependent parameter setting)
• Set P052= 0 and press the <P> key (terminate the "initialize" function)
• Set P052= 1 (select the function "Generate manufacturer setting"; when the <P> key is pressed, all
parameters are reset to their factory setting or to the P077-dependent value)
If only
those parameter values that are dependent on P077 are required to be changed and all other
parameters should remain unchanged, the following procedure is necessary:
• Set P051= 3 (expert mode)
• Set P052= 2 (select "Initialize" function (set MLFB))
• Note P070 and set P070= 0
• Set P077= 5 or 6 (select the required P077-dependent parameter setting)
• Set P052= 0 and press the <P> key (read in the parameter values dependent on P077)
• Move the F060 error message into the "background" by pressing <P>+<H>
• Set P052= 2 (select "Initialize" function (set MLFB) again)
• P070= noted value (restore MLFB)
• P052= 0 and press the <P> key (MLFB is read in and the dependent parameters P071, P075 and P076
are set)
• Move the F060 error message into the "foreground" again by pressing <P>+<T>, and reset by pressing
the <P> key
Additional parameter settings for the 12-pulse slave:
• P051= 3 (expert mode)
• P688 = 1 (Peer-to-Peer protocol)
• Switch off earth short-circuit test (P354 = 0), when the unit is supplied from an unearthed supply, e.g.
from the delta winding of the 12-pulse transformer
• For factory settings in accordance with P077= 5 or 6, binary input 1 is a source for "No external fault 1"
and binary input 2 is a source for "No external warning 1". If this is not required, e.g. in the case of open
terminals, P575 = 1 and P588 = 1 must be set.
