Execute "Drive commissioning" menu command
● When using the STARTER commissioning tool for commissioning:
Start the project wizard
For a 12-pulse series connection, restricted redundant operation is possible. With the setting
p51803 = 1, if a slave fails (devices with setting p51800 = 23 or 24) then, depending on the
minimum number of power units (set in p51802), this is tolerated. Master devices (12 pulse -
master p51800 = 21, or 12 pulse slave - p51800 = 22) must remain operational. The drive is
shut down if one of the two fails. It is not possible to transfer the master – and redundancy of
armature and field (setting, p51803 = 2) is not possible. If the electronic supply fails, or
devices are removed with active bus terminating resistor, then for the device in front, the bus
terminating resistor should be activated using p51801 = 1. When reinstalling the previously
removed device, the change must be appropriately undone (p51801 = 0).
