Operation
These warnings are intended for all who plan the operation of the drive or operate
the drive. Ignoring the instructions can cause physical injury or death and/or damage
to the equipment.
WARNING
-
Before adjusting the drive and putting it into service, make sure that the motor
and all driven equipment are suitable for operation throughout the speed range
provided by the drive. The drive can be adjusted to operate the motor at
speeds above and below the base speed.
-
Do not control the motor with the disconnecting device (disconnecting mains);
instead, use the control panel keys
and , or commands via the I/O
board of the drive.
-
Mains connection:
You can use a disconnect switch (with fuses) to disconnect the electrical
components of the drive from the mains for installation and maintenance work.
The type of disconnect switch used must be as per EN 60947-3, Class B, so as
to comply with EU regulations, or a circuit-breaker type which switches off the
load circuit by means of an auxiliary contact causing the breaker's main
contacts to open. The mains disconnect must be locked in its "OPEN" position
during any installation and maintenance work.
-
EMERGENCY STOP buttons must be installed at each control desk and at all
other control panels requiring an emergency stop function. Pressing the STOP
button on the control panel of the drive will neither cause an emergency stop of
the motor, nor will the drive be disconnected from any dangerous potential.
-
To avoid unintentional operating states, or to shut the unit down in case of any
imminent danger according to the standards in the safety instructions it is not
sufficient to merely shut down the drive via signals "RUN", "drive OFF" or
"Emergency Stop" respectively "control panel" or "PC tool".
-
Intended use:
The operating instructions cannot take into consideration every possible case
of configuration, operation or maintenance. Thus, they mainly give such advice
only, which is required by qualified personnel for normal operation of the
machines and devices in industrial installations.
If in special cases the electrical machines and devices are intended for use in
non-industrial installations - which may require stricter safety regulations (e.g.
protection against contact by children or similar) - these additional safety
measures for the installation must be provided by the customer during
assembly.
Note:
-
When the control location is not set to Local (Local not shown in the status row
of the display), the stop key on the control panel will not stop the drive. To stop
the drive using the control panel, press the Loc/Rem key and then the stop key
.
