(
3AXD50001017705 [English]).
Install the drive
WARNING! ACS280 drive may become damaged if operated without a suitable
heat-sink. Do not operate the drive without providing suitable heat-sink capacity
for the drive and application requirement.
•
ACS280 must be mounted onto a suitable flat metallic surface with sufficiently low
thermal resistance to allow dissipation of the heat produced.
For detailed information,
please refer to the
Planning the cooling of the drive in ACS280 Hardware Manual
(
3AXD50001017705 [English]).
1. Make marks onto the surface for the mounting holes. Refer to
.
Download the mounting template on
library.abb.com
.
2. Drill the holes for the mounting screws. If necessary, install suitable plugs or anchors into
the holes.
3. Apply the thermal compound onto the cold-plate surface of the drive. About how to
properly apply the thermal compound, refer to
ACS280 Hardware Manual
(
3AXD50001017705 [English]).
4. Put the drive onto the mounting holes.
5. Tighten the mounting screws.
Measure the insulation resistance
Drive:
Do not do voltage tolerance or insulation resistance tests on the drive, because this can
cause damage to the drive.
Input power cable:
Before you connect the input power cable, measure the insulation of the
input power cable. Obey the local regulations.
Motor and motor cable:
1.
Make sure that the motor cable is connected to the motor and disconnected from the
drive output terminals T1/U, T2/V and T3/W.
2.
Use a voltage of 1000
V DC to measure the
insulation resistance between each phase
conductor and the protective earth
conductor. The insulation resistance of an
ABB motor must be more than 100 Mohm (at
25 °C [77 °F]). For the insulation resistance of
other motors, refer to the manufacturer’s
documentation.
Moisture in the motor decreases the
insulation resistance. If you think that there
is moisture in the motor, dry the motor and
do the measurement again.
Make sure that the drive is compatible with the
grounding system
You can connect all drive types to a symmetrically grounded TN-S system (center-grounded
wye). The drive is delivered with the metal EMC and VAR screws installed. There are also spare
plastic EMC/VAR screw included in drive delivery. The table shows when to use the metal
EMC/VAR screw
(connect the internal EMC filter) or plastic EMC/VAR screw(disconnect the
internal EMC filter).
Note:
Not all ACS280 drives have the EMC/VAR screw, check hardware manuals for details.
Connect the power cables
Connection diagram
(shielded cables)
1.
Disconnecting device.
2.
Two protective earth (ground) conductors. Drive safety standard IEC/EN61800-5-1
requires two PE conductors, if the cross-sectional area of the PE conductor is less than
10 mm
2
Cu or 16 mm
2
Al. For example, you can use the cable shield in addition to the
fourth conductor.
3.
Use a separate grounding cable or a cable with a separate PE conductor for the line side,
if the conductivity of the fourth conductor or shield does not meet the requirements for
the PE conductor.
4.
Use a separate grounding cable for the motor side, if the conductivity of the shield is not
sufficient, or if there is no symmetrically constructed PE conductor in the cable.
5.
Do the 360-degree grounding of the cable shield for the motor cable and brake resistor
cable outside the drive and as close to the power terminals as possible. It is also
recommended for the input power cable.
6.
Brake resistor and resistor cable (optional).
Connection procedure
(shielded cables)
For the tightening torques, refer to ACS280 Hardware Manual (
3AXD50001017705 [English]).
1.
Strip the motor cable.
2. Twist the motor cable shield into a
bundle, mark it and connect it to
the grounding screw and ground
the shield under the grounding
clamp outside the drive close to
the terminals.
3. Connect the phase conductors of
the motor cable to terminals T1/U,
T2/V and T3/W.
4. If you use a brake resistor, connect
the brake resistor cable to
terminals R- and UDC+. Use a
shielded cable and ground the
shield under the grounding clamp
outside the drive close to the
terminals.
5. Strip the input power cable.
6. If the input power cable has a shield, ground the shield under the grounding clamp
outside the drive close to the terminals. Then twist the shield into a bundle, mark it and
connect it to the grounding terminal.
7. Connect the PE conductor of the input power cable to the grounding terminal. If
necessary, use a second PE conductor, connect to a second PE connection point which
must be well conducted with the drive's cold plate and as close to the drive as possible.
8. In 3-phase drives, connect the phase conductors of the input power cable to terminals L1,
L2 and L3. In 1-phase drives, connect the phase and neutral conductors to terminals L and
N.
9.
Mechanically attach the cables on the outside of the drive.
Connect the control cables
Connection procedure
Do the connections according to your
control requirements. Keep the signal
wire pairs twisted as near to the
terminals as possible to prevent
inductive coupling.
1. Strip a part of the outer shield of
the control cable for grounding.
2. Use a screw to connect the outer
shield to the grounding tab.
3. Strip the control cable conductors.
4. Connect the conductors to the
correct control terminals. Insert
the conductor into a push-in
terminal. To release, pull the
conductor with pushing the open/

Safe torque off (STO)
The drive has a Safe torque off function (STO) in accordance with IEC/EN 61800-5-2. It can be
used, for example, as the final actuator device of safety circuits that stop the drive in case of
danger (such as an emergency stop circuit).
When activated, the STO function disables the control voltage of the power semiconductors
of the drive output stage, thus preventing the drive from generating the torque required to
rotate the motor. The control program generates an indication as defined by parameter
31.22.
If the motor is running when Safe torque off is activated, it coasts to a stop. Closing the
activation switch deactivates the STO. Any faults generated must be reset before restarting.
The STO function has a redundant architecture, that is, both channels must be used in the
safety function implementation. The safety data given is calculated for redundant use, and
does not apply if both channels are not used.
WARNING!
The STO function does not disconnect the voltage from the main and
auxiliary circuits of the drive.
Notes:
•
If stopping by coasting is not acceptable, stop the drive and machinery using the
appropriate stop mode before activating the STO.
•
The STO function overrides all other functions of the drive.
Wiring
The safety contacts must open/close within 200 ms of each other.
Double-shielded twisted-pair cable is recommended for the connection. The maximum length
of the cabling between the switch and the drive control unit is 300 m (1000 ft). Ground the
shield of the cable at the control unit only.
Validation
To ensure the safe operation of a safety function, a validation test is required. The test must
be carried out by a competent person with adequate expertise and knowledge of the safety
function. The test procedures and report must be documented and signed by this person.
Validation instructions of the STO function can be found in the drive hardware manual.
Technical data
•
Minimum voltage at S1 and S2 to be interpreted as “1”: 13 V DC
