General safety in operation
These instructions are for all personnel that operate the drive.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
• If you have a cardiac pacemaker or other electronic medical device, keep away from
the area near motor, drive, and the drive power cabling when the drive is in operation.
There are electromagnetic fields present which can interfere with the function of
such devices. This can cause a health hazard.
• Give a stop command to the drive before you reset a fault. If you have an external
source for the start command and the start is on, the drive will start immediately
after the fault reset, unless you configure the drive for pulse start. See the firmware
manual.
• 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".
Note:
• 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 need
to start or stop the drive, use the control panel keys or commands through the I/O
terminals of the drive.
Additional instructions for permanent magnet motor drives
￭ Safety in installation, start-up, maintenance
These are additional warnings concerning permanent magnet motor drives. The other
safety instructions in this chapter are also valid.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
If you are not a qualified electrical professional, do not do installation or
maintenance work.
• Do not do work on the drive when a rotating permanent magnet motor is connected
to it. A rotating permanent magnet motor energizes the drive including its input and
output power terminals.
