1) I: Input; IO: Input/output; M: Measuring signal; NC: NC contact; S: Supply
2) Can be freely parameterized
3) When connecting contacts AS1/AS2 in series, a contact voltage drop up to max. 0.2 V must be taken into account for
the lifetime of the contacts (100000 switching operations). For a 24 V switching voltage, due to the non–linear contact
characteristics, from experience, five contacts can be simply connected in series without encountering any problems.
4) In accordance with EN 60204–1 (machine safety) control–power transformers should be provided when
AC control voltages are used.

S Reference:
Maximum current(for the total group):
Note:
The enable voltage (terminal 9) can be used to supply the
enable signals (e.g. pulse enable) as 24 V auxiliary voltage.
I Voltage tolerance(including ripple):
Typ. current consumption:
Note:
The pulse enable acts simultaneously on drive A and drive B.
When this pulse enable is withdrawn, the drives "coast down"
unbraked.
S Note:
If the enable signals are to be controlled from an external volt-
age source, the reference potential (ground) of the external
source must be connected to this terminal.
IO Type: 9–pin D–sub socket connector
