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 damage to the
printed circuit boards:
Wear a grounding wrist band when handling the boards. Do not touch the
boards unnecessarily. The printed circuit boards contain components sensitive
to electrostatic discharge.
WARNING! Ignoring the following instructions can cause physical injury or
death, or damage to the equipment:
Before you connect voltage to the drive, make sure that the drive covers are
on. Keep the covers on during the operation.
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.
Before you activate the automatic fault reset or automatic restart functions of
the drive control program, make sure that no dangerous situations can occur.
These functions reset the drive automatically and continue operation after a
fault or supply break.
The maximum number of drive power-ups is five in ten minutes. Too frequent
power-ups can damage the charging circuit of the DC capacitors.
Make sure that any safety circuits (for example, emergency stop and Safe
torque off) are validated in start-up. See chapter Start-up for reference of the
validation instructions.
Note:
If you select an external source for start command and it is ON, the drive will
start immediately after an input voltage break or fault reset unless the drive is
configured for 3-wire (a pulse) start/stop.
When the control location is not set to local, the stop key on the control panel
will not stop the drive.
