•

Do not do the grinding procedure in haz-

ardous ambience.

•

Ensure that keys are protected against ejec-

tion.

Enable the safety devices and monitoring sys-

tems of the machine.

Commissioning

Once all requirements are met, proceed as fol-

lows:

•

Commission the drive system according

to the instructions of the corresponding

product documentation. The respective

information can be found in the functional

description of the drive controllers.

•

Record all measures taken in the commis-

sioning log.

Observe the general and technology-dependend

safety instructions in this documentation.
For commissioning of the controllers and control

systems, additional steps may be required. The

inspection of the functioning and performance

of the systems is not object of these Operating

Instructions; instead, it is carried out within the

framework of the commissioning of the machine

as a whole. Comply with the information and

instructions of the machine manufacturer.

9.4

Operation

CAUTION

Explosion hazard!
Do not install the amplifier (drive controller) in a

hazardous area.

CAUTION

Explosion hazard!
Do not operate the motor in potentially explosive

atmospheres if any mounting screws or covers

are removed. Do not remove any screws or

covers while the motor is in a potentially explo-

sive area.

CAUTION

Explosion hazard!
Do not operate the motor outside the parameters

shown in the motor performance curves

During operation, keep the ambient and opera-

tion conditions and technical data specified in

the operating instruction and project planning

manual.
Checks during operation:

•

Pay attention to exceptional noise.

•

Pay attention to increased vibrations.

•

Check the motor for cleanliness.

•

Check the monitoring devices and diag-

nostic / error messages of the controllers.

Decommission the drive when deviations from

normal operation exist. For further procedure

refer to

Maintenance

10.1 Cleaning and servicing

WARNING

Operations in the vicinity of live parts are

extremely dangerous.

−

Work required on the electric system may

only be carried out by skilled electricians.

Tools for electricians (VDE tools) are abso-

lutely necessary.

−

Isolate (even auxiliary circuits).

−

Secure against reactivation.

−

Ensure de-energization.

−

Ground and short-circuit.

−

Cover or shield any adjacent live parts.
