• 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 drive power cycles is five times in ten minutes. Power cycling the
drive too often can damage the charging circuit of the DC capacitors.
• If you have connected safety circuits to the drive (for example, Safe torque off or
emergency stop), validate them at start-up. See separate instructions for the safety
circuits.
• Beware of hot air exiting from the air outlets.
• Do not cover the air inlet or outlet when the drive is running.
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.
• If the drive is in remote control mode, you cannot stop or start the drive with the
control panel.
• Only authorized persons are allowed to repair a malfunctioning drive.
