5.3 Supply
●
Danger of death, serious injury and/or damage to property due to
undefined states of the drive controller, caused by common feeding
of the power and logic supply!
In order to ensure fault-free operation, a separate voltage source must
be provided for the supply of the power unit and the logic unit.
The encoTRive may only be operated on power supplies in accordance with the requirements of
PELV (IEC 60364-4-41:2005) or with a safety transformer in accordance with the requirements of
IEC 61558-2-6.
An additional fuse of 500 mA (fast) is recommended in the supply line to the logic unit. A 16 A fuse
should be provided in the supply line to the power unit (note actual drive power and cable cross-
sections used).
Logic unit
Rated voltage ............................................................. 24 V DC, ± 10 %
non-destructive up to ..................................................
≤ 28 V DC
Power consumption at rated voltage .......................... < 5 watts
Power unit
Supply range, variant-dependent ...............................
24…48 V DC, see nameplate
non-destructive up to .................................................
≤ 54 V DC
Power consumption, variant-dependent .................... see nameplate
Readiness for operation after switching on ..................
25 s
If the supply for the power unit is connected after the supply for the logic unit, the
drive software will generate an error. This must be acknowledged via the relevant
fieldbus interface.
Only when the start-up has been completed without error do the digital outputs and
LEDs assume their correct state.
