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 positioning 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, 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 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 positioning controller 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 device.
Also make sure that the external power supply of the controller (24 V) is
switched off.
The DC bus circuit or the mains supply must always be switched off prior to
switching off the 24 V controller supply.
