Electricity safety
WARNING! Ignoring the instructions can cause physical injury or death, or damage to the equipment.
Only qualified electricians are allowed to install and maintain the drive!

Never work on the drive, motor cable or motor when input power is applied. After disconnecting the input power, always
wait for 10 minutes to let the intermediate circuit capacitors discharge before you start working on the drive, motor or motor
cable.
Always ensure by measuring with a multimeter (impedance at least 1 Mohm) that:
1. There is no voltage between the drive input phases L1, L2 and L3 and the ground.
2. There is no voltage between terminals + and BR and the ground.

Do not work on the control cables when power is applied to the drive or to the external control circuits. Externally supplied
control circuits may carry dangerous voltage even when the input power of the drive is switched off.

Do not make any insulation or voltage withstand tests on the drive.

Be sure the system is properly grounded before applying power. Do not apply AC power before you ensure that all grounding
instructions have been followed. Electrical shock can cause serious or fatal injury
Note:
Even when the motor is stopped, dangerous voltage is present at the power circuit terminals L1, L2, L3 and U, V, W and + and BR.
11
General safety


Make sure that dust from drilling does not enter the drive during the installation. Electrically conductive dust inside the drive may
cause damage or lead to malfunction.

Ensure sufficient cooling.
Safety in start-up and operation
These warnings are intended for all who plan the operation, start up or operate the drive.
WARNING! Ignoring the following instructions can cause physical injury or death, or damage to the equipment.

Before adjusting the drive and putting it into service, make sure that the motor and all driven equipment are suitable for
operation throughout the speed range provided by the drive. The drive can be adjusted to operate the motor at speeds
above and below the speed provided by connecting the motor directly to the power line.

Do not activate automatic fault reset functions if dangerous situations can occur. When activated, these functions reset the
drive and resume operation after a fault.

Do not control the motor with an AC contactor or disconnecting device (disconnecting means); use instead the control panel
start and stop keys and or external commands (I/O). The maximum allowed number of charging cycles of the DC capacitors
(that is, power-ups by applying power) is two per minute.
Note:

When parameter 1103 PRIMARY COMMAND SOURCE MODE is not set to 1 or 2, the stop key on the control panel will not
stop the drive. To stop the drive open terminal 2 of the drive control terminals.

avoided, could result in damage to the equipment and
other than electrical, which if not avoided, could result
possible injury or death.
in damage to property.
This ACS250 variable speed drive is intended for professional installation and commissioning into complete equipment or systems
as part of a fixed installation. If installed incorrectly it may present a safety hazard. The ACS250 uses high voltages and currents,
carries a high level of stored electrical energy, and is used to control mechanical plant that may cause injury. Close attention is
required to system design and electrical installation to avoid hazards in either normal operation or in the event of equipment
malfunction. Only qualified electricians are allowed to install and maintain this product.
System design, installation, commissioning and maintenance must be carried out only by personnel who have the necessary
training and experience. They must carefully read this safety information and the instructions in this Guide and follow all
information regarding transport, storage, installation and use of the ACS250, including the specified environmental limitations.
Do not perform any flash test or voltage withstand test on the ACS250. Any electrical measurements required should be carried out
with the ACS250 disconnected.
Electric shock hazard! Disconnect and ISOLATE the ACS250 before attempting any work on it. High voltages are present at the
terminals and within the drive for up to 10 minutes after disconnection of the electrical supply. Always ensure by using a suitable
multimeter that no voltage is present on any drive power terminals prior to commencing any work.
Where supply to the drive is through a plug and socket connector, do not disconnect until 10 minutes have elapsed after turning off
the supply.
Ensure correct grounding connections and cable selection as per defined by local legislation or codes. The drive may have a leakage
current of greater than 3.5mA; furthermore the earth cable must be sufficient to carry the maximum supply fault current which
normally will be limited by the fuses. Suitably rated fuses should be fitted in the mains supply to the drive, according to any local
legislation or codes.
Do not carry out any work on the drive control cables when power is applied to the drive or to the external control circuits.
The “Safe Torque Off” Function does not prevent high voltages from being present at the drives power terminals.
Within the European Union, all machinery in which this product is used must comply with the Machinery Directive 2006/42/EC,
Safety of Machinery. In particular, the machine manufacturer is responsible for providing a main switch and ensuring the electrical
equipment complies with EN60204-1.
The level of integrity offered by the ACS250 control input functions – for example stop/start, forward/reverse and maximum speed,
is not sufficient for use in safety-critical applications without independent channels of protection. All applications where
malfunction could cause injury or loss of life must be subject to a risk assessment and further protection provided where needed.
The driven motor can start at power up if the enable input signal is present.
The STOP function does not remove potentially lethal high voltages. ISOLATE the drive and wait 10 minutes before starting any
work on it. Never carry out any work on the Drive, Motor or Motor cable when the input power is still applied.
The ACS250 can be programmed to operate the driven motor at speeds above or below the speed achieved when connecting the
motor directly to the mains supply. Obtain confirmation from the manufacturers of the motor and the driven machine about
suitability for operation over the intended speed range prior to machine start up.
Do not activate the automatic fault reset function on any systems whereby this may cause a potentially dangerous situation.
IP66 drives provide their own pollution degree 2 environments. IP20 drives must be installed in a pollution degree 2 environment,
mounted in a cabinet with IP54 or better.
ACS250s are intended for indoor use only.
When mounting the drive, ensure that sufficient cooling is provided. Do not carry out drilling operations with the drive in place,
dust and metal shavings from drilling may lead to damage.
The entry of conductive or flammable foreign bodies should be prevented. Flammable material should not be placed close to the
drive
Relative humidity must be less than 95% (non-condensing).
Ensure that the supply voltage, frequency and number of phases correspond to the rating of the ACS250 as delivered.
Never connect the mains power supply to the Output terminals U, V, W.
Do not install any type of automatic switchgear between the drive and the motor
Wherever control cabling is close to power cabling, maintain a minimum separation of 4in. (100 mm) and arrange crossings at 90
degrees
Ensure that all terminals are tightened to the appropriate torque setting
Do not attempt to carry out any repair of the ACS250. In the case of suspected fault or malfunction, contact your local ABB Drives
representative for further assistance.

Installation should be in a suitable enclosure, according to EN60529 or other relevant local codes or standards.
Enclosures should be made from a thermally conductive material.
Where vented enclosures are used, there should be free space clearance above and below the drive to ensure good air circulation –
see the diagram below for minimum free space clearance. Air should be drawn in below the drive and expelled above the drive.
In any environments where the conditions require it, the enclosure must be designed to protect the ACS250 against ingress of airborne
dust, corrosive gases or liquids, conductive contaminants (such as condensation, carbon dust, and metallic particles) and sprays or
splashing water from all directions.
High moisture, salt or chemical content environments should use a suitably sealed (non-vented) enclosure.
The enclosure design and layout should ensure that the adequate ventilation paths and clearances are left to allow air to circulate through the
drive heatsink. Recommend below is the minimum mounting clearance requirements for drives mounted in non-ventilated metallic enclosures.

5. Electrical Installation
5.1. Grounding the Drive
This manual is intended as a guide for proper installation. ABB Drives Ltd cannot assume responsibility for the compliance or the
non-compliance to any code, national, local or otherwise, for the proper installation of this drive or associated equipment. A
hazard of personal injury and/or equipment damage exists if codes are ignored during installation.
This ACS250 contains high voltage capacitors that take time to discharge after removal of the main supply. Before working on the
drive, ensure isolation of the main supply from line inputs. Wait ten (10) minutes for the capacitors to discharge to safe voltage
levels. Failure to observe this precaution could result in severe bodily injury or loss of life.
Only qualified electrical personnel familiar with the construction and operation of this equipment and the hazards involved should
install, adjust, operate, or service this equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life.

5.1.2. Grounding Guidelines
The ground terminal of each ACS250 should be individually connected DIRECTLY to the site ground bus bar (through the filter if installed).
The ACS250 ground connections should not loop from one drive to another, or to, or from any other equipment. Ground loop impedance must
confirm to local industrial safety regulations. To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring
connections.
The drive Safety Ground must be connected to system ground. Ground impedance must conform to the requirements of national and local
industrial safety regulations and/or electrical codes. The integrity of all ground connections should be checked periodically.
5.1.3. Protective Earth Conductor
The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply conductor.
5.1.4. Safety Ground
This is the safety ground for the drive that is required by code. One of these points must be connected to adjacent building steel (girder, joist), a
floor ground rod, or bus bar. Grounding points must comply with national and local industrial safety regulations and/or electrical codes.
5.1.5. Motor Ground
The motor ground must be connected to one of the ground terminals on the drive.
5.1.6. Ground Fault Monitoring
As with all inverters, a leakage current to earth can exist. The ACS250 is designed to produce the minimum possible leakage current while
complying with worldwide standards. The level of current is affected by motor cable length and type, the effective switching frequency, the
earth connections used and the type of RFI filter installed. If a GFCI (Ground Fault Current Interrupter) is to be used, the following conditions
apply:

The device must be suitable for protecting equipment with a DC component in the leakage current

Individual GFCI’s should be used for each ACS250
5.1.7. Shield Termination (Cable Screen)
The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield connected to this terminal (drive end)
should also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to connect the shield to the safety ground
terminal.
5.2. Wiring Precautions
Connect the ACS250 according to section 5.9, ensuring that motor terminal box connections are correct. There are two connections in general:
Star and Delta. It is essential to ensure that the motor is connected in accordance with the voltage at which it will be operated. For more
information, refer to section 5.6 Motor Terminal Box Connections.
Type MC continuous corrugated aluminium armour cable with symmetrical grounds or shielded power cable is recommended for the motor
cables if metallic conduit is not used.
The power cables must be rated for 75 °C (167 °F).
5.3. Incoming Power Connection










Power should be connected to L1, L2, and L3. Phase sequence is not important.
For compliance with CE and C Tick EMC requirements, a symmetrical shielded cable is recommended.
For compliance with CSA requirements, transient surge suppression shall be installed on the line side of this equipment and shall be
rated 600V (phase to ground), 600V (phase to phase), suitable for overvoltage category III, and shall provide protection for a rated
impulse withstand voltage peak of 4 kV or equivalent.
A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the ACS250 and the AC
Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe, EN60204-1, Safety of
machinery).
The cables should be dimensioned according to any local codes or regulations. Guideline dimensions are given in section 11.2.
Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply line, according to the
data in section 11.2. The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or UL type T
fuses are suitable; however in some cases type aR fuses may be required. The operating time of the fuses must be below 0.5 seconds.
When the power supply is removed from the drive, a minimum of 30 seconds should be allowed before re-applying the power. A
minimum of 5 minutes should be allowed before removing the terminal covers or connection.
The maximum permissible short circuit current at the ACS250 Power terminals as defined in IEC60439-1 is 100kA.
An optional Input Choke is recommended to be installed in the supply line for drives where any of the following conditions occur:o The incoming supply impedance is low or the fault level / short circuit current is high.
o
If the transformer kVA rating is more than 10x the kVA rating of the drive or ensure that the per drive source
impedance is less than 0.5%
o The supply is prone to dips or brown outs
o An imbalance exists on the supply (3 phase drives)
o The power supply to the drive is via a busbar and brush gear system (typically overhead Cranes).
In all other installations, an input choke is recommended to ensure protection of the drive against power supply faults.
21
5.4. Compatibility with IT (ungrounded) and corner-grounded TN systems
WARNING! EMC filters should not be used when installing the drive on an IT system (an ungrounded
power system or high-resistance-grounded power system, otherwise the system will be connected to
ground potential through the EMC capacitors. This may cause danger or damage to the EMC filter.
If you have an IT (ungrounded) system or corner-grounded TN system, disconnect the internal Varistor
screw as shown below.
22
5.5. Drive and Motor Connection







The drive inherently produces fast switching of the output voltage (PWM) to the motor compared to the mains supply, for motors
which have been wound for operation with a variable speed drive then there is no preventative measures required, however if the
quality of insulation is unknown then the motor manufacturer should be consulted and preventative measures may be required.
The motor should be connected to the ACS250 U, V, and W terminals using a suitable 3 or 4 core cable. Where a 3 core cable is utilised,
with the shield operating as an earth conductor, the shield must have a cross sectional area at least equal to the phase conductors
when they are made from the same material. Where a 4 core cable is utilised, the earth conductor must be of at least equal cross
sectional area and manufactured from the same material as the phase conductors.
The motor earth must be connected to one of the ACS250 earth terminals.
For compliance with the European EMC directive, a suitable screened (shielded) cable should be used. Braided or twisted type
screened cable where the screen covers at least 85% of the cable surface area, designed with low impedance to HF signals are
recommended as a minimum. Installation within a suitable steel or copper tube is generally also acceptable.
The cable screen should be terminated at the motor end using an EMC type gland allowing connection to the motor body through the
largest possible surface area
Where drives are mounted in a steel control panel enclosure, the cable screen may be terminated directly to the control panel using a
suitable EMC clamp or gland, as close to the drive as possible.
For IP66 drives, connect the motor cable screen to the internal ground clamp
5.6. Motor Terminal Box Connections
Most general purpose motors are wound for operation on dual voltage supplies. This is indicated on the nameplate of the motor
This operational voltage is normally selected when installing the motor by selecting either STAR or DELTA connection. STAR always gives the
higher of the two voltage ratings. . Example Motor nameplate shown below (380V Delta illustrated):
5.7. Motor Thermal overload Protection.
5.7.1. Internal Thermal overload protection.
The drive has an in-built motor thermal overload function; this is in the form of an “F0009” trip after delivering >100% of the value set in
parameter 9906 MOTOR RATED CURRENT for a sustained period of time (e.g. 150% for 60 seconds).
5.7.2.
Motor Thermistor Connection
Where a motor thermistor is to be used, it should be connected as follows :Additional Information

Compatible Thermistor : PTC Type, 2.5kΩ trip level Use a setting of
parameter 9902 DIGITAL INPUTS FUNCTION SELECT that has Input 5
(terminal 10) function as External Trip, e.g. 9902 = 6.
Refer to section 8.1 for further details.
5.8. Control Terminal Wiring





All analog signal cables should be suitably shielded. Twisted pair cables are recommended.
Power and Control Signal cables should be routed separately where possible, and must not be routed parallel to each other.
Signal levels of different voltages e.g. 24 Volt DC and 600 Volt AC, should not be routed in the same cable.
Maximum control terminal tightening torque is 0.5Nm.

5.10. Safe Torque Off
Safe Torque OFF will be referred to as “STO” through the remainder of this section.
5.10.1. Responsibilities
The overall system designer is responsible for defining the requirements of the overall “Safety Control System” within which the drive will be
incorporated; furthermore the system designer is responsible for ensuring that the complete system is risk assessed and that the “Safety control
System” requirements have been entirely met and that the function is fully verified, this must include confirmation testing of the “STO” function
before drive commissioning.
The system designer shall determine the possible risks and hazards within the system by carrying out a thorough risk and hazard analysis, the
outcome of the analysis should provide an estimate of the possible hazards, furthermore determine the risk levels and identify any needs for risk
reduction. The “STO” function should be evaluated to ensure it can sufficiently meet the risk level required.
5.10.2. What STO Provides
The purpose of the “STO“ function is to provide a method of preventing the drive from creating torque in the motor in the absence of the “STO“
input signals (Terminal 12 with respect to Terminal 13), this allows the drive to be incorporated into a complete safety control system where
1
“STO“ requirements need to be fulfilled.
The “STO“ function can typically eliminate the need for electro-mechanical contactors with cross-checking auxiliary contacts as per normally
2
required to provide safety functions.
The drive has the “STO“ Function built-in as standard and complies with the definition of “Safe torque off“ as defined by IEC 61800-5-2:2007.
The “STO“ Function also corresponds to an uncontrolled stop in accordance with category 0 (Emergency Off), of IEC 60204-1. This means that
the motor will coast to a stop when the “STO” function is activated, this method of stopping should be confirmed as being acceptable to the
system the motor is driving.
The “STO“ function is recognised as a fail safe method even in the case where the “STO“ signal is absent and a single fault within the drive has
occured, the drive has been proven in respect of this by meeting the following safety standards :

Note : The values acheived above maybe jepardised if the drive is installed outside of the Environmental limits detailed in section 11.1 on page
60.
5.10.3. What STO does not provide
Disconnect and ISOLATE the drive before attempting any work on it. The “STO“ function does not prevent high voltages from being
present at the drive power terminals.
1
Note : The “STO“ function does not prevent the drive from an unexpected re-start. As soon as the “STO“inputs receive the relevant
signal it is possible (subject to parameter settings) to restart automatically, Based on this, the function should not be used for
carrying out short-term non-electrical machinery operations (such as cleaning or maintenance work).
2
Note : In some applications additional measures may be required to fulfil the systems safety function needs : the “STO“ function
does not provide motor braking. In the case where motor braking is required a time delay safety relay and/or a mechanical brake
arrangement or similar method should be adopted, consideration should be made over the required safety function when braking as
the drive braking circuit alone cannot be relied upon as a fail safe method.
25
5.10.4. “STO“ Operation
When the “STO” inputs are energised, the “STO” function is in a standby state, if the drive is then given a “Start signal/command” (as per the
start source method selected in parameter 9902 DIGITAL INPUTS FUNCTION SELECT) then the drive will start and operate normally.
When the “STO” inputs are de-energised then the STO Function is activated and stops the drive (Motor will coast), the drive is now in “Safe
Torque Off” mode.
To get the drive out of “Safe Torque Off” mode then any “Fault messages” need to be reset and the drive “STO” input needs to be re-energised.
5.10.5. “STO” Status and Monitoring
There are a number of methods for monitoring the status of the “STO” input, these are detailed below:
Drive Display
In Normal drive operation (Mains AC power applied), when the drives “STO” input is de-energised (“STO” Function activated) the drive will
highlight this by displaying “InHibit”, (Note: If the drive is in a tripped condition then the relevant trip will be displayed and not “InHibit”).
Drive Output Relay


Drive relay 1: Setting parameter 1401 USER RELAY 1 OUTPUT (TERMINALS 14, 15 & 16) FUNCTION SELECT to a value of “13” will result
in relay opening when the “STO” function is activated.
Drive relay 2: Setting parameter 1402 USER RELAY 2 OUTPUT (TERMINALS 17 & 18) FUNCTION SELECT to a value of “13” will result in
relay opening when the “STO” function is activated.

5.10.6. “STO” Function response time
The total response time is the time from a safety related event occurring to the components (sum of) within the system responding and
becoming safe. (Stop Category 0 in accordance with IEC 60204-1)



The response time from the “STO” inputs being de-energised to the output of the drive being in a state that will not produce torque in
the motor (“STO” active) is less than 1ms.
The response time from the “STO” inputs being de-energised to the “STO” monitoring status changing state is less than 20ms
The response time from the drive sensing a fault in the STO circuit to the drive displaying the fault on the display/Digital output
showing drive not healthy is less than 20ms.

5.10.7. “STO” Electrical Installation
The “STO” wiring shall be protected from inadvertent short circuits or tampering which could lead to failure of the “STO” input signal,
further guidance is given in the diagrams below.
In addition to the wiring guidelines for the “STO” circuit below, section 5.1.1 “Recommended installation for EMC compliance should also be
followed.
The drive should be wired as illustrated below; the 24Vdc signal source applied to the “STO” input can be either from the 24Vdc on the drive or
from an External 24Vdc power supply.

5.10.8. Enabling the “STO” Function
The “STO” function is always enabled in the drive regardless of operating mode or parameter changes made by the user .
5.10.9. Testing the “STO” Function
Before commissioning the system the “STO” function should always be tested for correct operation, this should include the following tests:

With the motor at standstill, and a stop command given to the drive (as per the start source method selected in parameter 9902
DIGITAL INPUTS FUNCTION SELECT):
o De-energise the “STO” inputs (Drive will display ““InHibit”).
o Give a start command (as per the start source method selected in parameter 9902 DIGITAL INPUTS FUNCTION SELECT) and
check that the drive still displays “Inhibit” and that the operation is in line with the section 5.10.4 “STO“ Operation and
section 5.10.5 “STO” Status and Monitoring

With the motor running normally (from the drive):
o De-energise the “STO” inputs
o Check that the drive displays “InHibit” and that the motor stops and that the operation is in line with the section 5.10.4
“STO“ Operation and section 5.10.5 “STO” Status and Monitoring
5.10.10. “STO” Function Maintenance.
The “STO” function should be included within the control systems scheduled maintenance program so that the function is regularly tested for
integrity (Minimum once per Year), furthermore the function should be integrity tested following any safety system modifications or
maintenance work.
If drive fault messages are observed refer to section 12.1 for further guidance.

potentiometer. The display shows zero speed in Hz (.) with the potentiometer turned to minimum.
Turn the potentiometer to maximum. The motor will accelerate to 60Hz, the default value of parameter 2008, under the control of the
acceleration ramp time parameter 2202.
If the potentiometer is turned to minimum, the motor will decelerate to 0Hz, the default minimum speed set in parameter 2007, under
the control of the deceleration ramp parameter 2203. The output speed can be adjusted anywhere between minimum and maximum
speed using the potentiometer.

7.3. Sensorless Vector Speed Control Mode
ACS250 can be programmed by the user to operate in Sensorless Vector mode, which provides enhanced low speed torque, optimum motor
speed regulation regardless of load and accurate control of the motor torque. In most applications, the default Voltage Vector control mode will
provide adequate performance, however if Sensorless Vector operation is required, use the following procedure.




Enter the motor nameplate details into the relevant parameters as follows
o 9905 MOTOR RATED VOLTAGE
o 9906 MOTOR RATED CURRENT
o 9907 MOTOR RATED FREQUENCY
o (Optional) 9908 MOTOR RATED SPEED (Rpm)
o 9915 Motor Power Factor Cos Ø
Select Sensorless Vector control mode by setting parameter 9903 MOTOR CONTROL MODE = 0
Ensure that the motor is correctly connected to the drive
Carry out a motor data Autotune by setting parameter 9910 MOTOR PARAMETER AUTO-TUNE ENABLE = 1
The Autotune will begin immediately when parameter 9910 MOTOR PARAMETER AUTO-TUNE ENABLE = 1 is set regardless of
the status of the drive enable signal. Whilst the autotune procedure does not drive or spin the motor, the motor shaft may still
turn slightly. It is not normally necessary to uncouple the load from the motor; however the user should ensure that no risk
arises from the possible movement of the motor shaft.
It is essential that the correct motor data is entered into the relevant drive parameters. Incorrect parameter settings can result
in poor or even dangerous performance.

Drive operation limits
This parameter is only valid in vector speed control mode and will come into function once
the drive DC bus voltage increases above a preset limit
This voltage limit is set internally just below the over voltage trip level. This parameter will
effectively limit the output torque current in order to prevent a large current flowing back to
the drive, which may cause an Over-voltage trip. A small value in this parameter will limit the
motor control torque when the drive DC bus voltage exceeds the preset limit. A higher value
may cause a significant distortion in the motor current, which may cause an aggressive,
rough motor behaviour.

Sets the proportional gain value for the speed controller when operating in Vector Speed or
Vector Torque motor control modes (parameter 9903 MOTOR CONTROL MODE = 0 or 1).
Higher values provide better output frequency regulation and response. Too high a value can
cause instability or even over current trips. For applications requiring best possible
performance, the value should be adjusted to suit the connected load by gradually increasing
the value and monitoring the actual output speed of the load until the required dynamic
behaviour is achieved with little or no overshoot where the output speed exceeds the
setpoint.
In general, higher friction loads can tolerate higher values of proportional gain, and high

EFFECTIVE SWITCHING
FREQUENCY
The Energy Optimiser attempts to reduce the overall energy consumed by the drive and
motor when operating at constant speeds and light loads. The output voltage applied to the
motor is reduced. The Energy Optimiser is intended for applications where the drive may
operate for some periods of time with constant speed and light motor load, whether
constant or variable torque.
Voltage boost is used to increase the applied motor voltage at low output frequencies, in
order to improve low speed and starting torque. Excessive voltage boost levels may result in
increased motor current and temperature, and force ventilation of the motor may be
required.
An automatic setting () is also possible, whereby the ACS250 will automatically adjust
this parameter based on the motor parameters measured during an autotune.
Effective power stage switching frequency. The range of settings available and factory
default parameter setting depend on the drive power and voltage rating. Higher frequencies
reduce the audible ‘ringing’ noise from the motor, and improve the output current
waveform, at the expense of increased drive losses. Refer to section 11.5.3 on page 61 for
further information regarding operation at higher switching frequency.

10.Serial communications
10.1. RJ45 Connector Pin Assignment
ACS250 has an RJ45 connector on the front of the control panel. This connector allows the user to set up a drive network via a wired connection.
The connector contains multiple interfaces for different communication protocols.

PC and peripheral connection only

Modbus RTU

CANBus
The Remote keypad connection is always available, and can be used simultaneously with other interfaces, however only one other interface may
be used, e.g. If Modbus RTU is in use, CAN is disabled.
The electrical signal arrangement of the RJ45 connector is shown as follows:

10.2. Modbus RTU Communications
10.2.1. Modbus Telegram Structure
The ACS250 supports Master / Slave Modbus RTU communications, using the 03 Read Holding Registers and 06 Write Single Holding Register
commands. Many Master devices treat the first Register address as Register 0; therefore it may be necessary to convert the Register Numbers
detailed in section 10.2.4 by subtracting 1 to obtain the correct Register address. The telegram structure is as follows.

Notes
Command control word used to control the ACS250 when operating with Modbus
RTU. The Control Word bit functions are as follows :Bit 0 : Run/Stop command. Set to 1 to enable the drive. Set to 0 to stop the drive.
nd
Bit 1 : Fast stop request. Set to 1 to enable drive to stop with 2 deceleration ramp.
Bit 2 : Reset request. Set to 1 in order to reset any active faults or trips on the drive.
This bit must be reset to zero once the fault has been cleared.
Bit 3 : Coast stop request. Set to 1 to issue a coast stop command.
Setpoint must be sent to the drive in Hz to one decimal place, e.g. 500 = 50.0Hz
Setpoint must be sent to the drive in % to one decimal place, e.g. 2000 = 200.0%
This register specifies the drive acceleration and deceleration ramp times used when
Fieldbus Ramp Control is selected (2210 FIELDBUS RAMP CONTROL = 1) irrespective of
the setting of 1103 PRIMARY COMMAND SOURCE MODE. The input data range is from
0 to 60000 (0.00s to 600.00s)
This register contains 2 bytes.
The Lower Byte contains an 8 bit drive status word as follows :Bit 0 : 0 = Drive Disabled (Stopped), 1 = Drive Enabled (Running)
Bit 1 : 0 = Drive Healthy, 1 = Drive Tripped
The Upper Byte will contain the relevant fault number in the event of a drive trip.
Refer to section 12.1 on page 62 for a list of fault codes and diagnostic information

10.2.3. Modbus Parameter Access
All User Adjustable parameters are accessible by Modbus, except those that would directly affect the Modbus communications, e.g.

5302 DRIVE FIELDBUS ADDRESS

5303 Modbus RTU Baud Rate

5304 Modbus Data Format

5305 CAN Open Baud Rate
All parameter values can be read from the drive and written to, depending on the operating mode of the drive – some parameters cannot be
changed whilst the drive is enabled for example.
When accessing a drive parameter via Modbus, the Register number for the parameter is in the order of the long parameter list (See page 43
with the first register being 129 (Parameter 0401 TRIP HISTORY LOG).
Modbus RTU supports sixteen bit integer values, hence where a decimal point is used in the drive parameter; the register value will be multiplied
by a factor of ten,
E.g. Read Value of parameter 2008 = 500, therefore this is 50.0Hz.
For further details on communicating with ACS250 using Modbus RTU, please refer to your local ABB representative.

Relative Humidity
: < 95% (non condensing)
Note
:
Drive must be Frost and moisture free at all times
Installation above 2000m is not UL approved
11.2. Input/Output Current ratings and fuses
The following tables provide the output current rating information for the various ACS250 models. ABB Drives always recommend that selection
of the correct ACS250 is based upon the motor full load current at the incoming supply voltage.
Cable dimensioning for nominal rated currents is shown in the table below together with the corresponding fuse types for short-circuit
protection of the input power cable.
The rated fuse currents given in the table are the maximums for the mentioned fuse types. If smaller fuse ratings are used, check that the fuse
rms current rating is larger than the nominal input current .
If 150% output power is needed, multiply nominal input current by 1.5.
Check that the operating time of the fuse is below 0.5 seconds. The operating time depends on the fuse type, the supply network impedance as
well as the cross-sectional area, material and length of the supply cable. In case the 0.5 seconds operating time is exceeded with the gG or T
fuses, ultra rapid (aR) fuses in most cases reduce the operating time to an acceptable level.
Note: Larger fuses must not be used when the input power cable is selected according to this table.

Note
Input current measurements are at 575VAC at drive nominal output current.
Ratings shown above apply to 40°C Ambient temperature. For derating information, refer to section 11.5.1 on page 61.
The maximum motor cable length stated applies to using a shielded motor cable. When using an unshielded cable, the maximum cable length
limit may be increased by 50%. When using the ABB Drives recommended output choke, the maximum cable length may be increased by 100%
The PWM output switching from any inverter when used with a long motor cable length can cause an increase in the voltage at the motor
terminals, depending on the motor cable length and inductance. The rise time and peak voltage can affect the service life of the motor. ABB
Drives recommend using an output choke for motor cable lengths of 50m or more to ensure good motor service life
For UL compliant installation, use Copper wire with a minimum insulation temperature rating of 70°C, UL Class CC or Class J Fuses
11.3.
Overload
The ACS250 can deliver 150% of the drive nominal output current for 60 seconds and 200 % for 3 seconds.
61
11.4. Additional Information for UL Approved Installations
ACS250 is designed to meet the UL requirements. In order to ensure full compliance, the following must be fully observed.
Input Power Supply Requirements
Supply Voltage
500-600 Volts, + / - 10% variation allowed, Maximum 660 Volts RMS
Imbalance
Maximum 3% voltage variation between phase – phase voltages allowed
All ACS250 units have phase imbalance monitoring. A phase imbalance of > 3% will result in the drive tripping. For
input supplies which have supply imbalance greater than 3% (typically the Indian sub- continent & parts of Asia Pacific
including China) ABB Drives recommends the installation of input line reactors. Alternatively.

All the drives in the above table are suitable for use on a circuit capable of delivering not more than the above
specified maximum short-circuit Amperes symmetrical with the specified maximum supply voltage.
Incoming power supply connection must be according to section 5.9
All ACS250 units are intended for indoor installation within controlled environments which meet the condition limits shown in section 11.1 on
page 60.
Branch circuit protection must be installed according to the relevant national codes. Fuse ratings and types are shown in section 11.2 on page
60.
Suitable Power and motor cables should be selected according to the data shown in section 11.2 on page 60.
Power cable connections and tightening torques are shown in section 4.4 on page 15.
ACS250 provides motor overload protection in accordance with the National Electrical Code (US).

11.5.4. Example of applying Derating Factors
If a 5 HP IP66 drive is to be used at an altitude of 2000 metres above sea level, with 12kHz switching frequency and 45°C ambient temperature.
From the table above, we can see that the rated current of the drive is 9.5 Amps at 40°C,
Firstly, apply the swicthing frequency derating, 12kHz, 25% derating
9.5 Amps x 75% = 7.1 Amps
Now, apply the derating for higher ambient temperature, 2.5% per °C above 40°C = 5 x 2.5% = 12.5%
7.1 Amps x 87.5% = 6.2 Amps
Now apply the derating for altitude above 1000 metres, 1% per 100m above 1000m = 10 x 1% = 10%
7.9 Amps x 90% = 5.5 Amps continuous current available.
If the required motor current exceeds this level, it will be neccesary to either
Reduce the switching frequency selected
Use a higher power rated drive and repeat the calculation to ensure sufficient output current is available.

External trip
Ensure the connected brake resistor is above the minimum permissible level for the drive –
refer to the ratings shown in section 11.2.
Check the brake resistor and wiring for possible short circuits.
The drive software has determined that the brake resistor is overloaded, and trips to protect
the resistor. Always ensure the brake resistor is being operated within its designed parameter
before making any parameter or system changes.
To reduce the load on the resistor, increase deceleration the time, reduce the load inertia or
add further brake resistors in parallel, observing the minimum resistance value for the drive
in use.
Fault Occurs on Drive Enable
Check the motor and motor connection cable for phase – phase and phase – earth short
circuits.
Check the load mechanically for a jam, blockage or stalled condition
Ensure the motor nameplate parameters are correctly entered in parameter 9905, 9906, and
9907.
If operating in Vector mode (Parameter 9903 – 0 or 1), also check the motor power factor in
parameter 9915 and ensure an autotune has been successfully completed for the connected
motor.
Reduced the Boost voltage setting in parameter 2603
Increase the ramp up time in parameter 2202
If the connected motor has a holding brake, ensure the brake is correctly connected and
controlled, and is releasing correctly
Fault Occurs When Running
If operating in Vector mode (parameter 9903 – 0 or 1), reduce the speed loop gain in
parameter 2301
Check to see when the decimal points are flashing (drive in overload) and either increase
acceleration rate or reduce the load.
Check motor cable length is within the limit specified for the relevant drive in section 10.2
Ensure the motor nameplate parameters are correctly entered in parameter 9905, 9906, and
9907.
If operating in Vector mode (Parameter 9903 – 0 or 1), also check the motor power factor in
parameter 9915 and ensure an autotune has been successfully completed for the connected
motor.
Check the load mechanically to ensure it is free, and that no jams, blockages or other
mechanical faults exist
Check the wiring to motor and the motor for phase to phase and phase to earth short
circuits. Disconnect the motor and motor cable and retest. If the drive trips with no motor
connected, it must be replaced and the system fully checked and retested before a
replacement unit is installed.
The value of the DC Bus Voltage can be displayed in parameter 0107
A historical log is stored at 256ms intervals prior to a trip in parameter 0191
This fault is generally caused by excessive regenerative energy being transferred from the
load back to the drive. When a high inertia or over hauling type load is connected.
If the fault occurs on stopping or during deceleration, increase the deceleration ramp time
2203 or connect a suitable brake resistor to the drive.
If operating in Vector Mode, reduce the speed loop gain in parameter 2301
This occurs routinely when power is switched off.
If it occurs during running, check the incoming supply voltage, and all connections into the
drive, fuses, contactors etc.
The heatsink temperature can be displayed in parameter 0110.
A historical log is stored at 30 second intervals prior to a trip in parameter 0193
Check the drive ambient temperature
Ensure the drive internal cooling fan is operating
Ensure that the required space around the drive as shown in sections 0 on page 17 has been
observed, and that the cooling airflow path to and from the drive is not restricted
Reduce the effective switching frequency setting in parameter 2606
Reduce the load on the motor / drive
Trip occurs when ambient temperature is less than -10°C. The temperature must be raised
over -10°C in order to start the drive.
Press STOP key, the drive is now ready to be configured for the required application
