 The combination is possible without restrictions.

The combination is possible with restrictions:

 The EMC protection of the device is not effective in the DC-bus connection. Check whether EMC measures

are required for the entire DC-bus connection or machine.

 The braking circuit of the drive axis cannot be dimensioned in the DSD. DSD only dimensions a central brak-

ing circuit as it is for example contained in the 9400 power supply module.

If alternative or additional brake choppers are to be set in the drive axes, these braking circuits have to be

checked manually.

 No or no sufficient starting current limitation available. Special measures have to be taken. Please contact

your Lenze sales partner.

 The combination is not reasonable since the power range of the power supply module or the regenerative

power supply module is too low. If the DSD does not display an active message when the module is selected,

you can use this combination.
