100% of maximum value
1) The force is controlled and evaluated by regulating the motor current. A torque level or a linear force can be determined from the level
of current measured depending on the mechanism of the drive. The target is set as a percentage of the rated motor current and may
deviate from the actual force on the drive unit. If force levels are set low, the influence of friction in the system on the running beha-
viour and the actual force on the drive unit must also be taken into account.

13.2 Diagnostic messages
Diagnostic messages are classified as information, warnings or errors. If an error occurs, operation is
interrupted and the power stage is switched off. Warnings and errors remain active until the cause of
the event has been corrected. After the cause has been eliminated, warnings are automatically deleted
from the diagnostic memory with the next motion task. If errors occur, the error must be acknow-
ledged.
13.2.1 Acknowledge error
Corrected errors must be acknowledged.
Errors can be acknowledged as follows:
–
Restart (removal of logic voltage)
– IO-Link parameters (Quit Error)
The error is automatically deleted from the diagnostic memory on acknowledgement.
Errors on the EMCS-ST can be acknowledged via the following interfaces:
Error acknowledgement Operation
Restart:
Logic voltage = 0 V DC IO-Link parameters:
0x0029.3
0x0107.0
Quit Error = true
DIO operation (digital
inputs/outputs) Yes No
