Reference for the
external supply
S
The external supply is required for the 4 digital out-
puts (O0.A, O1.A and O0.B, O1.B).
When dimensioning the external power supply, the
total current of all of the digital outputs must be
taken into account.

Note:
The enable voltage (terminal 9) can be used to supply
the enable signals (e.g. pulse enable) as 24 V auxil-
iary voltage.
