INFORMATION
• Just like the input of a drive controller, the incoming side of the MOVIDRIVE
®
MDR60A1320-503-01 is not overload protected. Make sure during dimensioning
that the maximum DC input current of the driver controller (including overload
factor) does not exceed the input current of the regenerative power supply unit. If
that is the case nevertheless, the programmable motor current limit of the drive
controller should be identical to that of the regenerative power supply unit. You will
have to take the overload factor of the drive controller into consideration in this in-
stance as well.
• Keep in mind when determining the regenerative power that the actual current re-
generative power always depends on the actually existing line voltage.
7.4 Fuses and cable cross sections
The line connection of the regenerative power supply unit takes place via terminals L1,
L2 and L3 at the commutation choke and PE on the heat sink. Match the input fuse
according to the current carrying capacity of the permitted connection lead. The listed
manufacturers are recommendations only; you can certainly use comparable types
from other manufacturers.
7.4.1 Fuses to connect to incoming cable
Connect the semiconductor fuses listed in the following table to the incoming cable in
the regenerative power supply unit.
