Display and operating components (HMI)
The display and operating components (HMI) can be used to perform the fol-
lowing functions in the HMI menu:
–
Unlock pushbutton actuators (Unlock HMI), press and hold for 3 s
— an
active positioning task in DIO or IO-Link mode is stopped
(Condition for IO-Link operation: IO-Link parameter 0x000C.4 = false)
–
Select menu function with pushbutton actuators (selecting menu), press
–
Parameterise Speed Out, Speed In and Force setpoint values
(Set value: 10, 20, ..., 100% of the maximum value
save (Save), press
–
Parameterise the position of the reference end position "Ref" (Set Ref) and run

Homing with end position determination
WARNING
Risk of injury due to unexpected movement of components.
When starting the homing run, the drive is disconnected from the power supply
for a short time. This can cause unexpected movements of the connected
mechanics and crush parts of the body.
• Bring moving parts of the connected mechanical system into a safe position.
• Referencing with end position determination is only required again if the refer-
ence end position "Ref" or the useful range needs to be changed.
• During referencing with end position determination the intermediate position
Pos
Imp
and the start press position Pos
Start Press
is set equal to the new end
position Lim
Out
.
During referencing with end position determination the positions of the mechan-
ical stops Mech
In
/Mech
Out
are recorded in order to calculate the end positions
Lim
In
("Ref")/Lim
Out
for the dimension reference system.
Before running referencing with end position determination to a new reference
end position "Ref", the drive is de-energised for a required re-initialisation. Then
the power is restored and the process is started.
