11.5 Cold start
For proper function, Zimmer GmbH recommends that the actuator and sensor voltage be supplied with power separately.
The sensor supply must be switched on first.
As soon as the product is communicating with the PLC, the actuator power supply can be switched on.
Depending on the application, simultaneous activation of both voltages is also possible.
INFORMATION
If the sensor supply is disconnected, the C/Q signal (IO-Link) must be disconnected as well.
11.6 Minimum travel path
The gripping force of products with a self-locking mechanism is determined by a combination of the current and kinetic
energy of the system.
To increase the gripping force, the product must reach a minimum speed. For each attainable maximum force, there is a
different minimum travel path per gripper jaw depending on the installation size.

NOTICE
►
Before each homing command, make sure that the product is able to move freely and easily and that it cannot
be blocked by the gripper jaws or interfering edges.
When blocking, the reference position is set. A Homing command is not permitted in the gripped state.
There are various Homing commands available.
