2.4 Residual dangers
Consider the residual dangers mentioned in this chapter when assessing the risks associated with
your machine.
DANGER
Hazard caused by high operating voltage!
Extremely hazardous voltages of up to DC 900 V may occur!
The high operating voltage may cause muscle cramps, burns,
unconsciousness, respiratory standstill, or death.
•
Do not remove any cover plates and keep all control cabinet doors
closed during operation.
•
Check that all live connections are protected against contact.
•
Do not open the motor housing.
•
While the motor is in operation, do not touch the following
terminals: Power supply, motor voltage and DC link voltage.
DANGER
Danger in potentially explosive atmospheres!
Do not disconnect any plugs during operation!
The drive can become an ignition source in potentially explosive areas if you
disconnect the control or power plugs of the drive during operation.
•
Never pull the motor connector while the motor is energized.
•
Do not disconnect any connectors on the servo amplifier and the control
unit while higher currents are flowing.
DANGER
Danger in potentially explosive atmospheres!
Motor power limitations!
The motor can become an ignition source in potentially explosive areas if the
following instructions are not followed during operation.
•
Limit electrical disturbances and vibrations by fine-tuning the control
parameters.
•
The maximum speed must never be exceeded.
•
The RMS value for rated current must not exceed the specifications on
the nameplate.
•
For a rated speed close to 0, the RMS value of the rated current
indicated on the nameplate must be halved.
DANGER
Danger for persons with pacemakers and implants!
Electromagnetic fields caused by the drive!
Electric, magnetic and electromagnetic fields pose a particular hazard to
people with pacemakers, implants or similar devices.
•
You must not be in the immediate vicinity of the drive if you belong to
