1. the machine is switched off!
2. all connectors are disengaged!
Observe the ESD precautions!
Make sure that the connector contacts are clean!
3. Reestablish all required connections and secure them mechanically.
Make the required settings on the PWM.
Switch the machine and the control back on again.
Note
Observe the safety precautions below to avoid injury or damage to persons or products.
To avert potential dangers, only use the product in the manner described!
Attention
Check whether the machine axis can be traversed in a controlled manner.
During the start-up phase of the machine, the emergency stop button must be accessible
in time.
DANGER
Do not operate defective units!
No persons are permitted in the traverse range of the machine.
Do not change any parameters or encoder voltages at the test units while the machine tool
is moving and a test unit is connected to the position control loop!
Changed parameters must be reset to their original values.
Ensure that vertical axes cannot fall down!
The ATS software offers the possibility of storing and editing machine-specific or
equipment-specific information in the customer’s memory area. The data may comprise
safety-relevant information.
When servicing, please take care to adjust this memory area. Noncompliance with this
