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 Supply voltage of PDC
Infeed points Nominal supply
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 57.6 V DC is also permitted.
1)
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
(https://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.
