2.3 Power supply
2.3
Power supply
Infeed points
You supply the PDC at the logic unit (1L+, 2L+) and power unit (4L+) infeed points with the
following voltages:
Table 2-1

Infeed point
Nominal sup‐
ply voltage
Logic unit
24 V DC
1L+, 2L+
Power unit
24 to 48 V DC
4L+
When energy recovery is activated, a supply voltage above 52.8 V DC (maximum value
1)
58.8 V) is also permitted. Use a suitable bi-directional supply to ensure
that the voltage at 4L+ never exceeds 60 V DC during operation or under fault conditions.
It is essential that you observe the information on recovery in the section "Energy recovery"
in the system manual SIMATIC MICRO-DRIVE Drive controller PDC Drive controller PDC
support.industry.siemens.com/cs/ww/en/view/109774126).
Use separate power supply units to supply the logic unit and the power unit or a filter between
the shared power supply unit and the power supply.
Power supply for the power unit
You must feed the power supply for the power unit via terminals 4L+ and 4M at the X5050
interface (Figure 3-1 Connections of PDC1000 drive controller with pin assignment (Page 19)).
NOTICE
A two-pole miniature circuit breaker according to UL category DIVQ (UL 498) must be inserted
in the 4L+ and 4M feed line. You can find the article numbers of the miniature circuit breakers
to be used in the section "Accessories/Spare parts" in the System Manual SIMATIC MICRO-DRIVE
Drive controller PDC (https://support.industry.siemens.com/cs/ww/en/view/109774126).
The miniature circuit breaker must be implemented with two poles even when using PELV.
