2.2.1 Operational Safety
Operational safety
•
Safety-related applications are only allowed if they are explicitly and unambiguously mentioned in this manual.
•
All applications that can cause hazards to people or damage to property are safety-related applications.
•
The stop functions implemented in the software of the PLC do not interrupt the mains supply to the Power Supply Module
(PSM 510). Therefore, they must not be used for electrical safety for the servo system.
•
The servo system can be brought to a stop by a software command or a zero speed setpoint, however DC voltage remains present
on the servo drives and/or mains voltage in the PSM 510. Also, when the system is stopped, it may start up again on its own if the
circuitry is defective or after the elimination of a temporary overload, a problem with the supply voltage, or a problem with the
system. If personal safety considerations (for example, risk of personal injury caused by contact with moving machine parts after an
unintended start) make it necessary to ensure that an unintended start cannot occur, these stop functions are not sufficient. In this
case, ensure that the servo system is detached from the mains network, and prevent unintended motor starting, for example by
using the Safe Torque Off function.
•
The servo system may start running unintentionally during parameter configuration or programming. If this poses a risk to
personal safety (for example, risk of personal injury due to contact with moving machine parts), prevent unintended motor
starting, for example by using the Safe Torque Off function, or by safe disconnection of the servo drives.
•
In addition to the L1, L2, and L3 supply voltage inputs on the PSM 510, the servo system has other supply voltage inputs, including
external auxiliary voltage. Before commencing repair work, check that all supply voltage inputs have been switched off and that
the necessary discharge time for the DC-link capacitors has elapsed.
2.3 Important Safety Warnings
The following safety instructions and precautions relate to the VLT® Multiaxis Servo Drive MSD 510 system. Read the safety instructions
carefully before starting to work in any way with the servo system or its components. Pay particular attention to the safety instructions
in the relevant sections of this manual.
WARNING
HAZARDOUS SITUATION
If the servo drive or the bus lines are incorrectly connected, there is a risk of death, serious injury, or damage to the unit.
-
Always comply with the instructions in this manual and national and local safety regulations.
WARNING
HIGH VOLTAGE
The MSD 510 system contains components that operate at high voltage when connected to the electrical supply network.
There are no indicators on the components that indicate the presence of mains supply. Incorrect installation, commissioning, or
maintenance may lead to death or serious injury.
-
Installation, commissioning, and maintenance may only be performed by qualified personnel.
WARNING
LEAKAGE/GROUNDING CURRENT HAZARD
Leakage/grounding currents are >3.5 mA. Improper grounding of the MSD 510 system modules may result in death or serious
injury.
-
For reasons of operator safety, use a certified electrical installer to ground the system correctly in accordance with the
applicable local and national electrical standards and directives, and the instructions in this manual.
