1.5 Start-up and operation
The drive converter 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
converter 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 converter.
►
Secure motors against automatic restart.
cAUTION
High temperatures at heat sink and coolant!
burning of the skin!
►
Cover hot surfaces safe-to-touch.
►
If necessary, attach warning signs on the system.
►
Before touching, check the surface and cooling water lines.
►
Before working let the unit cool down.
• During operation, all covers and doors shall be kept closed.
• Use only approved accessories for this device.
• Never touch terminals, busbars or cable ends.
Observe the following instructions if the drive converter for
more than one year was not in operation before start-up.

Switching at the output
Switching between motor and drive converter is prohibited for single drives during op-
eration as this may trigger the protection gear of the device. Function “speed search”
must be activated if switching can not be avoided. Control release 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 converter 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 converter (mains on) (e.g. due to large rotating masses).
