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 controller 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, e.g. 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
drive controller 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 controller and up to 5 minutes thereafter. Contact may result in death or
serious personal injury.
