ACH580 Ultra-Low Harmonic Drives Installation, Operation and Maintenance Manual
• Before you connect voltage to the drive,
make sure that the drive covers are on.
Keep the covers on during the operation.
• Before you adjust the drive operation limits,
make sure that the motor and all driven
equipment can operate throughout the
range of 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.
• If you have connected safety circuits to the
drive (for example, emergency stop and
Safe torque off), validate them at the start
up. For the validation of the Safe torque off,
see ACH580 HVAC control program
firmware manual (3AXD50000027537
[English]). For the validation of other safety
circuits, see the instructions provided with
them.
Note:
• If you select an external source for start
command and it is on, and the start
command is level-triggered, the drive will
start immediately after fault reset. See
parameters 20.02 Ext1 start trigger type

• When the control location is not set to HAND
(text Hand is not shown on the top row of the
panel and parameter 19.19 HAND/OFF
disable action has value OFF button
disabled), the OFF key on the control panel
will not stop the drive.

• Frame R3: Do not attempt to repair a
malfunctioning drive; contact your local
representative for replacement or repair by
authorized persons.
• Frames R6 and R8: Can be repaired by
authorized persons.
Electrical safety in installation,
start-up and maintenance
Precautions before electrical work
These warnings are for all personnel who do
work on the drive, motor cable or motor.
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
electrical installation or maintenance work. Go
through these steps before you begin any
installation or maintenance work.
1. Clearly identify the work location.
2. Secure a permit to work from the person in
control of the electrical installation work.
3. Disconnect all possible voltage sources.
Lock and tag.
• Open the main disconnector at the power
supply of the drive.
• Make sure that reconnection is not
possible.
• Disconnect any external power sources
from the control circuits.
• After you disconnect the drive, always
wait for 5 minutes to let the intermediate
circuit capacitors discharge before you
continue.
4. Protect any other energized parts in the
work location against contact.
5. Take special precautions when close to bare
conductors.
