5 Maximum outputs power consump-
tion when inductive loads are
switched off
Figure 1 Maximum outputs power consumption when
inductive loads are switched off
The specifications in the diagram refer to a maximum
switching frequency of 1Hz.
The diagram displays the maximum amount of energy that
may be fed back into the the corresponding output groups
(outputs 1 to 8, 9 to 16, 17 to 24, 25 to 32) for each switch off
procedure during switching off of an inductive load without
external freewheeling circuit.
The current data refers to the ohmic DC voltage component
of the inductive load.

NOTE: Damage to the electronics
When you use an external freewheel limit, the
free-wheeling voltage to a maximum of -15V.
The value must be above -15V, so-12V, for
example.
The external freewheel limit has no function
with a higher negative voltage.
