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 or damage the
equipment.
•
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 activate automatic fault reset functions of the Standard Application
Program if dangerous situations can occur. When activated, these functions
will reset the drive and resume operation after a fault.
•
Do not control the motor with the disconnecting device (disconnecting switch);
instead, use the control panel keys and , or commands via the I/O
board of the drive.
•
Mains connection
You can use a switch disconnector (with fuses) in the power supply of the
thyristor power converter to disconnect the electrical components of the unit
from the power supply for installation and maintenance work. The type of
disconnector used must be a switch disconnector 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 disconnector 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 thyristor power converter will neither cause
an emergency motor stop, 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 system 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.
