cAUTION
High temperatures at motor housing !
Burning of the skin!
►
Cover hot surfaces safe-to-touch.
►
Before working let the motor cool down.
►
Before touching, check the surface and cooling water lines.
►
If necessary, attach warning signs on the system.
1.5 Start-up and operation
The drive controller must not be started until it is determined that the installation com-
plies with the machine directive; Account is to be taken of
WARNING
Software protection and programming !
Hazards caused by unintentional behavior of the drive!
►
Check especially during initial start-up or replacement of the drive
controller if parameterization is compatible to application.
►
Securing a unit solely with software-supported functions is not suf-
ficient. It is imperative to install external protective measures (e.g.
limit switch) that are independent of the drive controller.
►
Secure motors against automatic restart.
Switching at the output
Switching between motor and drive controller is prohibited for single drives during ope-
ration as this may trigger the protection gear of the device. Function ‚speed search‘ must
be activated if switching can not be avoided. Speed search may only be triggered after
closing the motor contactor (e.g. by switching the control release).
Connecting and disconnecting is permissible with multiple motor drives if at least 1 mo-
tor is running during the switch-over process. The drive controller must be dimensioned
to the occurring starting currents.
The ‚speed search‘ function must be activated if the motor is still running during a restart
of the drive controller (mains on) (e.g. due to large rotating masses).
1.6 Maintenance
The following maintenance work has to be carried out when required, but at least once
per year by authorized and trained personnel. Check unit for loose screws and plugs
and tighten if necessary.
►
Check unit for loose screws and plugs and tighten if necessary.
► Clean motor from dirt and dust deposits. Pay attention especially to cooling fins and
protective grid of the fans.
►
Check the function of the auxiliary fans of the motors. The fans must be replaced in
case of audible vibrations or squeaking.
