Foreword
Notes on the documentation
This description is only intended for the use of trained specialists in control and automation engineering who are familiar with the applicable national
standards. It is essential that the documentation and the following notes and explanations are followed when installing and commissioning the
components. It is the duty of the technical personnel to use the documentation published at the respective time of each installation and
commissioning. 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. We reserve the right to
revise and change the documentation at any time and without prior announcement. 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!
Due to the DC link capacitors dangerous voltage (875VDC) may persist at the DC link contacts “ZK+ and ZK- (DC+ and DC-)“ and
“RB+ and RB-“ after the servo drive has been disconnected from the mains supply. After disconnecting the servo drive wait at
AX5101 - AX5125 and AX520x;
5 minutes
, at AX5140/AX5160/AX5172;
15 minutes
, at AX5190/AX5191;
30 minutes
and at
AX5192/AX5193;
45 minutes
and measure the voltage at the DC link contacts ZK+ and ZK- (DC+ and DC-). The device is safe
once the voltage has fallen below 50 V.
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.
