18 Safety instructions
•
Keep the cabinet doors closed when the drive is powered. With the doors open, a risk
of a potentially fatal electric shock, arc flash or high-energy arc blast exists. If you
cannot avoid working on a powered drive, obey the local laws and regulations on live
working (including – but not limited to – electric shock and arc protection).
•
Before you adjust the drive operation limits, make sure that the motor and all driven
equipment can operate throughout the set operation limits.
•
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. If
these functions are activated, the installation must be clearly marked as defined in
IEC/EN 61800-5-1, subclause 6.5.3, for example, "THIS MACHINE STARTS
AUTOMATICALLY".
•
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 at start-up. See chapter
other safety functions, see their separate instructions.
Note:
•
If you select an external source for the start command and it is on, the drive will start
immediately after fault reset unless you configure the drive for pulse start. See the
firmware manual.
•
When the control location is not set to Local, the stop key on the control panel will not
stop the drive.
•
Only authorized persons are allowed to repair a malfunctioning drive.
