5.4.2 Connection Type
“Indexer“
IMPORTANT
Malfunction due to missing I/O input voltage!
If the motor voltage is applied to L+ and M terminals, the indexer is in operation.
However, the indexer only outputs signals when the 24 V
DC
input voltage is ap-
plied to the I/O input.
– If the module is to be operated in the connection type “Indexer”, the 24 V volt-
age
must
be connected (+24 V and M terminals).
– The power supply at L+ terminal is
not necessary
!
– If voltage is applied to L+ terminal, a failure of the I/O voltage will not be de-
tected.

The following applies to controlling an external power stage during connection
type “Indexer”:
– The CLK output is actively high, i.e. the idle level of the clock signal is 0 V.
– The DIR output is at 0 V when the motor rotates in the positive direction the
position value is incremented). If the motor rotates in negative direction
(the position value is decremented), the output is +24 V.
– The RUN output is actively high when the motor is running.
