Figure 13: Mechanical connection
Do not exceed maximum torque: M3 threads = 1.0 Nm MAX, M4 threads = 2.0 Nm MAX
8.3 Electrical connection
As supplied, the module is configured so that the M8 connector carries both the power as well as the logic
parts for the integrated gripper control system. If your application requires the power and logic parts to be
separated, for instance if you would like to use an external relay to ensure that the gripping force is safely
switched off (cf. "safe torque off", STO), then the power and logic parts can be supplied separately. The
equivalent circuit for the power supply is shown in Figure 14. The power and logic supply are not electrically
isolated so they must use the same power supply unit. The common supply of load and logic is shown in
Figure 15. If the supply to the load is to be switchable in operation, then the connection can be arranged as
shown in Figure 16.
