1.2 Safety precautions
Before you integrate the test units into the position control loop of an NC controlled
machine tool make sure that
1. the machine is switched off and
2. all connectors are disengaged!
Observe the ESD precautions!
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!
DANGER
Do not operate defective units!
Do not operate the device, if power cord, power supply unit or test unit are damaged!
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!
Ensure that vertical axes cannot fall down!
The ATS software permits the user to save data on his specific machine or system in the
memory area for customers. The data may comprise information relevant to machine
safety.
When servicing, please take care to adjust this memory area. Failure to do so may result in
machine damage or personal injury!
When troubleshooting always contact the machine tool builder for information (e.g. meaning
of the data in the OEM memory).
Attention
Correct evaluation of the malfunction of an NC-controlled machine requires fundamental
knowledge about the machine tool, its drives, inverters and NCs as well as their interaction
with the measuring systems.
Improper operation of the NC, incorrect NC programming, or incorrect or non-optimized
machine parameter values can lead to faulty machine performance.
Careless treatment or use may cause considerable damage or injury to property or
persons.
HEIDENHAIN can accept no responsibility for direct or indirect damage or injury caused to
property or persons through improper use or incorrect operation of the machine.
Apart from the information in this manual the general instructions for safety and the
prevention of accidents must be observed.
