Foreword
Notes on the documentation
This description is only intended for trained specialists in control, automation and drive engineering who are familiar with the applicable national
standards. It is essential that the following notes and explanations are followed when installing and commissioning these components. The
responsible staff must ensure that the application or use of the products described satisfy all the requirements for safety, including all the relevant
laws, regulations, guidelines and standards.
Disclaimer
The documentation has been prepared with care. The products described are, however, constantly under development. For this reason, the
documentation may not always be have been fully checked for consistency with the performance data, standards or other characteristics described.
In the event that it contains technical or editorial errors, we retain the right to make alterations at any time and without warning. No claims for the
modification of products that have already been supplied may be made on the basis of the data, diagrams and descriptions in this documentation.
Appropriate use
The digital encoder cards are exclusively intended for application in the optional rear slot of a servo drive from the AX5000 series. The cards are
installed together with the servo drive as components in electrical systems and machinery and may only be used in this way.
Security
Safety rules
The responsible staff must ensure that the application or use of the products described satisfy all the requirements for safety, including all the
relevant laws, regulations and guidelines.
DANGER
Caution – Danger of death!
Even when the AX5000 is disconnected from the mains voltage, dangerous voltage continues to be present at the "X02" terminals
of the DC link: AX5101-AX5125 and AX52xx = 5 min., AX5140 = 15 min. and AX5160 – AX5193 = 30 min.. Never touch the
terminals within this period.
WARNING
Caution – Risk of injury!
Electronic equipment is not fail-safe. The machine manufacturer is responsible for ensuring that the connected motors and the
machine are brought into a safe state in the event of a fault in the drive system.
Attention
Destruction of the digital encoder card through electrostatic charging!
The digital encoder card is an ESD-sensitive component. Follow the usual ESD safety procedures when handling the card (anti-
static wrist straps, earthing of the relevant components, etc.).
Personnel qualification
This description is only intended for trained specialists in control, automation and drive engineering who are familiar with the applicable national
standards. Knowledge of machine safety legislation is compulsory.
