5.2 Auxiliary 24 V and Holding Brake supply (X2)
Note: Only use power supply with galvanic isolated SELV output voltage!
If a 24 V auxiliary power supply is installed in the switchgear cabinet for relays, contactors
or other devices, this 24 V can be used to supply also the servo drive (notice the current
rating of the power supply).
The drive has an additional input for the holding brake supply so that this supply can be
switched off independently from the auxiliary supply of the drive.
Note, that the return of the 24 V power supply has to be grounded near
the power supply.
