Input Function Description
DIN9 Controller enable With a rising edge, the controller will be initialised and enabled together
with the power stage. With a falling edge, the motor will be decelerated to
speed = 0 and the power stage will be switched off.
Error
acknowledgement If the controller indicates an error, the falling edge will be used to
acknowledge active errors. If the error acknowledgement has been
successful, the controller will change to "Ready for operation" and can be
enabled again with the next edge.
Limit switch
acknowledgement If the motor has reached a limit switch, the falling edge will be used to
allow traversing in the same direction.
DIN8 Positive limit switch Positive (DIN8) and negative (DIN7) setpoints will only be enabled, if the
limit switch inputs are connected with + 24 V (limit switches with NC
contact).
If no signal is received, the drive will decelerate to speed = 0 when the
current limit is reached, the power stage will remain on.
DIN7 Negative limit switch
DIN6 Positioning start With a rising edge, positioning will be executed with the selected
parameter set.
DIN5 Selection of

parameter set Selection of the positioning parameter group
(accelerations / times, positioning speed, subgroup selection with 16 target
positions)

5.4.10 Setting digital outputs
In positioning mode, you can inform the higher−level control via digital outputs that a
positioning process has been completed/is being completed.
The digital outputs can transfer the following information:
ƒ Target reached.
ƒ Remaining path to end of positioning process reached.
ƒ Homing completed.
Please see the chapter "Digital outputs" for the configuration of the digital outputs.
