6 Important information for commissioning
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.
Please be aware each time before commissioning the AX5000 that connected motors can
make uncontrolled movements, which cannot always be prevented even by the AX5000’s
integrated diagnostic system, or may permit uncontrolled movements until the diagnostic
system responds. Analyse your system and take suitable precautions to prevent damage
being caused by these uncontrolled movements.
Potential causes of uncontrolled movements:
The diagnostic system of the AX5000 is equipped with complex plausibility checks, which
constantly monitor installation, operation, parameterisation and operation and, if necessary,
interrupt them with a diagnostic message. The points listed below are naturally also
monitored as standard, but it is not possible to include all eventualities; therefore, with
respect to the following points, you must always consider whether the driven axes can only
perform permissible movements.
• Incorrect commutation results (e.g. during wake & shake), It is essential to observe
chapter “AX5000 User manualcommissioningcommutation methodscommutation
error “F2A0”” on our Homepage.
• Specific caution with motors of third parties: always execute the command „P-0-0166“
without load when changing the motor or feedback or when changing the SysMan-file
(.TSM) and evaluate the result. Correct the commutation offset if applicable., as described
in chapter “AX5000 User manual Commissioning Commutation methods”.
• Input of invalid parameters
• Measuring transducer and/or signal transducer defective or incorrectly adjusted
• Cables defective or not adequately screened
• Incorrectly attached sensors
CAUTION
Increased attention in the case of vertical axes!
When commissioning vertical axes, the risk consideration described above
is to be carried out with particular care. An uncontrolled movement can
mean the sudden falling down of a load in this case.
