Safety instructions 11
• 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 in start-up. See chapter Start-up in the hardware manual 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 fault reset unless you configure the drive for pulse start. See the
firmware manual.
• Depending on the wiring and parametrization of the drive, the stop key on the
control panel may not stop the drive.
• Only authorized persons are allowed to repair a malfunctioning drive.
