Rectifier/Regenerating Unit Operating Instructions
4.3.9.2 Initialization (MLFB setting) (P052 = 2)
This function is used to change the rectifier/regenerating unit MLFB (type setting).
The parameters P071, P075 and P076 are only set dependent on the new MLFB when changing the MLFB
.
"Initialization" can be selected in the following statuses: "Switch-on inhibit" (008), "Ready-to-switch-on" (009) or
"Fault" (007).
Procedure:
⇓ P051 = 3 Access stage "Expert mode" to permit access to P070
⇓ P052 = 2 Function selection "Initialization"
⇓ P070 Specification of the number of the MLFB of the rectifier/regenerating unit
(rating plate data on the unit) according to the table at the end of this Section.
⇓ P052 = 0 Terminate the function "Initialize"
⇓ P key The operating display appears and once the MLFB has been modified
, the
following parameters are reassigned in accordance with the MLFB:
P071 Rated voltage at the input to the rectifier bridge
P075 Rated DC current
P076 Only the ones position is modified
Ones position = 2, when rectifier and regenerating mode is
possible
Ones position = 1, when only rectifier mode is possible
(only set when P070 ≥ 101)
⇓ The operating display "Switch-on inhibit" (008) or "Ready-to-switch-on" (009) appears after
"Initialization" has been completed
