Safety instructions

Safe start-up and operation
General safety
These warnings are intended for all who plan the operation of the drive or operate
the drive.
WARNING! Ignoring the following 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 speed provided by connecting the motor directly to the
power line.
• Do not activate automatic fault reset functions of the drive control 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 (means); instead, use the
control panel keys and , or commands via the I/O board of the drive. The
maximum allowed number of charging cycles of the DC capacitors ie, power-ups
by applying power, is five in ten minutes.
• Do not use the Prevention of unexpected start function or Safe torque off function
for stopping the drive when the inverter unit(s) is running. Give a Stop command
instead.
Note:
• If an external source for start command is selected and it is ON, the drive (with
Standard Control Program) will start immediately after fault reset unless the drive
is configured for 3-wire (a pulse) start/stop.
• When the control location is not set to Local (L 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 .
Permanent magnet motor drives
These are additional warnings concerning permanent magnet motor drives.
WARNING! Do not run the motor above the rated speed. Motor overspeed leads to
overvoltage which may result in explosion of the capacitors in the intermediate circuit
of the drive.
