2.4.2 Safety notes for assembly and maintenance
The appropriate DIN, VDE, EN and IEC regulations as well as all national and local safety regulations
and rules for the prevention of accidents apply for the assembly and maintenance of the system. The
plant engineer or the operator is responsible for compliance with these regulations:
The servo drive must only be operated, maintained and/or repaired by personnel trained
and qualified for working on or with electrical devices.
Prevention of accidents, injuries and/or damages:
Additionally secure vertical axes against falling down or lowering after the motor has
been switched off, for example by means of:
Mechanical locking of the vertical axle,
External braking, catching or clamping devices or
Sufficient balancing of the axle
The motor holding brake supplied by default or an external motor holding brake driven
by the servo drive alone is not suitable for personal protection!
Keep the electrical equipment voltage-free using the main switch and protect it from
being switched on again until the DC bus circuit is discharged, in the case of:
Maintenance and repair work
Cleaning
long machine shutdowns
Prior to carrying out maintenance work make sure that the power supply has been
turned off, locked and the DC bus circuit is discharged.
The external or internal brake resistor carries dangerous DC bus voltages during
operation of the servo drive and up to 5 minutes thereafter. Contact may result in death
or serious personal injury. Wait for this time prior to performing any work on the affected
connections. Measure the voltages for your own protection. Contact with these high DC
bus circuit voltages may result in death or serious personal injury.
Be careful during the assembly. During the assembly and also later during operation of
the drive, make sure to prevent drill chips, metal dust or assembly parts (screws, nuts,
cable sections) from falling into the servo drive.
Also make sure that the external power supply of the servo drive (24 V) is switched off.
