Safety instructions
8
Start-up and operation
These warnings are intended for all who plan the operation of the drive, start up or
operate the drive.
WARNING! Ignoring the following instructions can cause physical injury or death,
or damage to 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 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 an AC contactor or disconnecting device
(disconnecting means); instead, use the control panel or external commands
via the I/O board of the drive or a fieldbus adapter. The maximum allowed
number of charging cycles of the DC capacitors (i.e. power-ups by applying
power) is one per two minutes. The maximum total number of chargings is
100000 for frame sizes A and B, 50000 for frame sizes C and D.
•
Drives controlling a permanent magnet motor: Do not run the motor over the
rated speed. Motor overspeed leads to overvoltage which may permanently
damage the drive.
Notes:
•
If an external source for start command is selected and it is ON, the drive will
start immediately after an input voltage break or a fault reset unless the drive is
configured for 3-wire (pulse) start/stop.
•
When the control location is not set to local, the stop key on the control panel
will not stop the drive.
WARNING! The surfaces of drive system components (such as the mains choke
and braking resistor, if present) become hot when the system is in use.
