Bypass contactor with I/R unit

If individual inverters have to be isolated when the DC busbar is supplied through an input/regenerative
feedback unit, the the appropriate parameter sets of the infeed/regenerative feedback unit must be
simultaneously switched-over using the binary input. An optimization run for each required constellation must
be executed to determine the appropriate parameters. A maximum of four parameter sets can be selected.
If the DC busbar is to be fed from an infeed/regenerative feedback unit, the control parameter values must be
determined for this infeed/regenerative feedback unit. During commissioning, the following steps are required:
♦ Re-parameterization for the optimization run:
Parameter-
No. Name
P629, i001 ST.BC energized
P612, i001 ST.BC energized
P600, i001 ST. ready to switch-on
Table 6.12 Parameterization for the optimization run
♦ Execute the optimization run to determine the values for the closed-loop control parameters for the
infeed/regenerative feedback unit (+ Instruction Manual, infeed/regenerative feedback unit).
♦ Re-parameterize for operation with the bypass contactor:
Parameter-
No. Name
P600, i001 ST.ready-to-switch-on
P629, i001 ST.BC energiz.
In this case, the converter must be externally supplied with 24 V DC (connector -X9: 1,2)
