7.5.2  Positioning mode 

The positioning mode is used when moving to a specific position. This is typically 

the case when a part is released, or the gripper fingers are pre-positioned. 
The positioning mode is active if the hook for current [%] is 

not

 set or the "Mode" 

signal via the bus is 

not

 activated (Fig. 11). 

Fig. 11 

Positioning mode servo gripper 

The following must always be observed in positioning mode: 

  The position must always be within the maximum position limits (between 

1000 and 21,000 µm). 

  If possible, the module should not be displaced to the position limits. 

 

 

A position selection between 0 µm and 20,000 µm is recommended. 

7.5.3  Current mode 

Current mode is used when driving on block. This is typically the case when a 

part is gripped. 
The current mode is active when the check mark for current [%] is 

set

 or the 

"Mode" signal is 

activated

 via the bus (Fig. 12). 

Fig. 12 

Current mode servo gripper 

The following should always be observed in the current mode: 

  The setting range for the current is between 20% and 100%. 

  After the gripping movement, you can see whether a part has been gripped. 

For this purpose, the target position of the gripping movement must be 

selected in such a way that the fingers do not close completely when no part 

is present. 

  If a part is gripped and thus the parametrized current value is reached, the 

controller sets the signal "move_ok". 

  If no part is present, the gripper reaches the parametrized target position, but 

not the parametrized current value. 

-  The controller does not set the signal "move_ok".
