9 Operation
WARNING!
Danger of burns from hot housing surfaces.
Metallic housing parts can reach high temperatures during operation.
Contact with metal housing parts can cause burn injuries.
•
Do not touch metallic housing parts.
• After the power supply is switched off, let the device cool down to room tem-
perature.
9.1 Master Control
– Lowest priority: DIO operation (after Power ON and initialisation)
– Medium priority: IO-Link operation (after established IO-Link communication)
– Highest priority: HMI operation (unlocked pushbuttons)
9.2 Dimension Reference System
The correct positioning of the drive requires a defined dimension reference sys-
tem.

9.3 Display and Operating Components (HMI)
The display and operating components (HMI) can be used to perform the follow-
ing functions in the HMI menu:
–
Unlock pushbutton actuators (Unlock HMI), press and hold for 3 s
(Condition for IO-Link operation: IO-Link parameter 0x000C.4 = false)
– Menu function with pushbutton actuators select (selecting menu), press
– Parameterise setpoint values Speed Out, Speed In and Force
(Set value: 10, 20, ..., 100% of maximum value

9.4 Homing
During homing, the positions of the mechanical stops Mech

for the
dimension reference system.
Before the homing run is carried out, the drive is de-energised for a required re-
initialisation. Then the power supply is restored and the homing process starts.
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 mechan-
ics and crush parts of the body.
•
Bring moving parts of the connected mechanical system into a safe position.
• A new homing is only necessary if the reference end position Ref or the useful
range is changed.
• When homing, the Start Press Position Pos

is equated with the new
end position Lim
