Input power activates the Line Rectifier of the Main Circuit Card which produces
pulsating d.c.voltage to the d.c. pircuit.This intennediate d.c. circuit filters the voltage to the Power Module which produces symmetrical three-phase a.c. voltage for
the motor. The Power Module used in the frequency converter is the latest IGBT
technology with intelligent protection capabilities integrated in the module. The input
power is almost entirely active power. Any losses in the Main Circuit Card are dissipated through the air-cooled heatsink.
Voltage waveform conversions and frequency converter status are controlled and
monitored by the Main Circuit Card. Interactions between required functions and
frequency converter status are controlled by the system software on the Control
Card. The Control Card contains the control connections for extemal operator controls. External control can be either by the removable Control Panel connected to
the Control Card or input/output connections from overriding control devices. The
Control Panel can fit directly on the frequency converter or externally with an additional cable. The Protection Cover provides the specified protection class.

2 Mechanical Installation
Cooling of the ACS 200 is based on natural air circulation (ACS 201-1P1-1 to ACS
201-1P6-1) or fan (other ACS 201 types).
Cooling
The maximum ambient operating temperature allowed is 50°C for constant torque
drives when the load current is lower than or equal to the continuous maximum load
current IN and switching frequency is lower than or equal to 8 kHz. 110 % IN continu. ous load is allowed when the ambient temperature is lower than or equal to 40°C
and switching frequency is lower than or equal to 8 kHz. The maximum ambient
operating temperature allowed for specified overload capacity is 40 °C, when the
load current is less than 150 % of IN (120 % of IN for ACS 201-4P1-1) lasting at most
one minute in every ten minutes. See figure 2-1 below for power derating curves.
The cooling air must be clean and free from corrosive materials. If the cooling air
contains dust, clean the cooling surfaces of the unit regularly using compressed air
and a brush.
ACS 200 frequency converters are to be used in a heated, indoor, controlled environment that is relatively free of moisture and conductive contaminates such as
condensation, carbon dust and the like.

3 Power Connections
The ACS 200 is designed for use on 208 to 240 V single-phase supplies (ACS 2012P1-1 to 4P1-1 can be used on a single-phase or a three-phase supply) and on 380
to 480 V three-phase supplies (ACS 201-1P6-3to 6P6-3).
Warning! Do not under any circumstances connect three-phase, 380 V (or higher)
voltage to the mains input terminals of the 208 to 240 V ACS 200.
Notel The factory setting of the 400 V series ACS 200 supply voltage (par. SUP
VOLT) is 480 V. If your supply voltage is much lower than 480 V (380 V, 400 V) you
may get an undervoltage fault when first using the ACS 200. After connecting the
mains cabling, change the value to correspond to the mains voltage. Press ~ to
reset the fault.
Mains cable
A three-conductor screened cable (single-phase with Protective Earth) or fourconductor (three-phase with Protective Earth) are recommended for the mains
cabling. The cables and fuses are to be dimensioned in accordance with the output
current. Refer to table 3-1 for minimum dimensions. When dimensioning cables and
fuses, always pay attention to local authority regulations.
All mains connections shall be rated for 60°C (140 OF) for use in ambient temperatures up to 45 °C (113 OF) or 75°C (168 OF) for use in ambient temperatures up to
50 °C (122 OF). All mains connections shall be torqued to 1 Nm (8.8 in. Ibs.).
Fast acting semiconductor type fuses must be installed ahead of the frequency
converter. Use of any type of fuse other than that recommended will fail to protect
the frequency converter and could void the guarantee. Refer to Table 3-1 for correct
fuse type and size.
Motor cable
A four-conductor screened cable (three-phase with Protective Earth) is recommended due to the rapid voltage changes occurring in variable frequency motor
drive systems.
Note! To avoid disturbances, install the motor cable away from other cable routes.
Avoid long parallel runs with other cables.
The rapid voltage changes cause capacitive current between the phase conductors
and the cable screen. This current increases with the switching frequency and motor
cable length. This phenomenon can cause substantially higher current measured by
the ACS 200 than the actual motor current, and can cause overcurrent tripping.
Cable lengths of 100 m should not be exceeded.

Insulation checks
&
Warning! Insulation checks are to be done before connecting the ACS 200 to the
mains. Before proceeding with the insulation resistance measurements, make sure
that the ACS 200 is disconnected from the mains. Failure to disconnect the mains
could result in death or serious injury.
1. Check that the motor cable is disconnected from the ACS 200 output on terminals
U2, V2 and W2.
2. Check that the motor cable is disconnected from the motor and remove bridging
connections at the motor.
3. Measure the insulation resistances from the motor. The voltage range of the
insulation resistance meter must be at least equal to the supply voltage, but not
exceeding 1000 V. The insulation resistance must be greater than 1 Mil.
14
Chapter 3 - Power Connections
4. Measure the insulation resistance of the motor cable between the phases and
between each phase and Protective Earth. The insulation resistance must be
greater than 1 MO.
Terminal connections
To connect the mains, motor and control cables, remove the front cover of the unit
by loosening the two screws at the bottom of the cover and pressing the tabs inward
(see figure 2-4 on page 11).
The TEMP LIM parameter provides motor thermal protection. If this feature is not
-used, the motor connected to the ACS 200 requires overload protection in accordance with the National Electric Code (U.S.A.).
The ACS 200 has been short circuit tested in accordance with UL 508.
The frequency converter is suitable for use on a circuit capable of delivering not
more than 5000 rms symmetrical amperes, 240 volts to 480 volts maximum, for the
208 - 240 volt or 380 - 480 volt units respectively.
Open the knock out holes in the lead-in insulator and fit standard conductor fittings.
Connect the mains and motor cables according to the layout in figure 3-1, page 15.
Warning! The braking resistor terminals carry a dangerous d.c. voltage. Only a
recommended braking resistor should be connected to the Main Circuit Card,
terminal block X5.
Note! If the motor cable has a separate screen in addition to the earth wire, the
screen is connected to the PE terminal at the frequency converter end only.
Unless you proceed with the control cable connections, attach the front cover of the
unit with the two screws.
Earthing and earth faults
The ACS 200 must always be earthed through an earthing conductor connected to
the earthing terminal (PE).
If the ACS 200 is connected to a system without system earth, the earth fault protection must be capable of starting at earth fault currents containing high frequency and
d.c. components. The ACS 200 earth fault protection guards only the frequency
converter itself against earth faults occuring in the motor or the motor cable.
It is NOT designed to protect personnel if they come in contact with the motor cable.
Fault current protective switches do not necessarily operate properly with frequency
converters. When using such switches, check their function at possible earth fault
currents arising in the fault situation.

4 Control Connections
The ACS 200 can be controlled by the ACS 200 Control Panel or by external control
signals connected to the terminal block X1 of the Control Card.
Control cables
Control cables for the ACS 200 should be 0.5 to 1.0 mm2 screened, multi-core
cables.
• The screens of the cables should be earthed at the frequency converter.
• Unscreened cables can be used for cable routes under 20 metres long.
• When planning the cabling between ACS 200 and an automation device, such as
a PLC, attention should be given to interference suppression, signal levels,
galvanic isolation, etc.
Note! The control connections of ACS 200 are galvanically isolated from the mains
but not from the frame earth.

I/O option switch S1 On the Control Card (See figure 4-1 on page 17) is used to
configure the digital inputs and the Control Panel lock-out. The ACS 200 control
input can be configured for threeJdifferent wired control modes with S1 ,A and S1 ,B:
• Standard (refer to figure 4-3 page 19 and tables 4-1 to 4-2 page 19)
• 3-wire (refer to figure 4-4 page 20 and tables 4-3 to 4-4 page 20)
• Alternate (refer to figure 4-5 page 21 and tables 4-5 to 4-7 page 21)
Note! The factory setting is Standard.
Switch S1,C is used to lock the Control Panel. If S1,C is in the OFF (0) position,
parameter programming can be changed and the control place can be switched to
local (panel control). If S1,C is in the ON (1) position, the Control Panel is locked
and parameter programming cannot be changed, but can be examined. When
locked, panel control is not allowed and "HARDWARE LOCK S1" message appears
on the Control Panel display if you try to use the panel keys.

3·Wire
3-Wire is for general industrial applications which usually require a three wire start!
stop signal for safety reasons. With 3-wire control, momentary start and stop pushbuttons are used. The Start button is normally open, and the Stop button is normally
closed. When operating from external momentary push-buttons, the ACS 200 requires a start command to be given after power is applied.
The stop input is active even when operating from the keypad, allowing the normally
closed contact from a motor overload relay or other external interlock to stop the
frequency converter when operating from the keypad. A connection must exist
between X1:5 and X1:7 for the frequency converter to operate.

Chapter 5 - Control and Parameter Logic
The ACS 200 frequency converter can be operated from external controls or directly
from the control panel. The firsttime the ACS 200 is connected to the mains, the
default control place is Remote (refer to Remote in this section for a description).
You can change the control place to Local (panel control) by pressing and holding
the ~ key down for two seconds. The associated LED will turn off indicating that
the ACS 200 is not under remote control.
Panel operation
Remote
When the ~ key is pressed, the associated light will turn on indicating that the
ACS 200 is under remote control. The ACS 200 is then controlled from the devices
connected to the terminal block X1 on the Control Card.
Local
Operation can be changed from Remote to Local in two ways, as described below.
The first method allows you to transfer running information from external devices to
the control panel while the ACS 200 is operating and without interrupting operation.
Press and hold the ~ key and the C]L) key simultaneously for two seconds. This
will transfer the current external reference to Page 1 parameter REF FREQ/LOC
FREQ. For example, if the drive is running in reverse at 45.7 Hz reference from the
analogue input, the panel frequency reference will now be 45.7 Hz; the panel direction will be reverse; and the panel run status will be run. The operator can now
change the frequency, direction and run status of the drive from the control panel.
If only the ~ key is pressed, the motor stops and the analogue input reference
value REF FREQ is transferred to LOC FREQ (Note! Constant speed reference is
not transferred). The motor can be started from the control panel within the limits
established by parameter settings.

6 Commissioning
Safety precautions
Before commissioning, observe the following warnings.
Warning! The Main Circuit Card (bottom card) and parts of the Control Card (upper
card) are at mains potential when the ACS 200 is connected to the mains. This
voltage is extremely dangerous and can cause death or severe injury if you come in
contact with it. When the supply voltages are disconnected from the terminal block
X1, it will take about five minutes before the capacitors in the intermediate d.c.
circuit are discharged to a safe voltage.
The "DANGER" (or "CHARGE") LED on the bottom left corner of the Main Circuit
Card will light when the potential in the frequency converter is unsafe. If the cover
has been removed and the "DANGER" (or "CHARGE") LED is on, verify that the
frequency converter has been disconnected from the mains and wait for the "DANGER" (or "CHARGE") LED to turn off. Even after the "DANGER" ("or CHARGE")
LED has turned off, there can be some residual charge in the d.c. link capacitors,
that can damage the electronics if accidently conducted to the Control Card. This is
why you have to wait 5 minutes before servicing the unit.
To ensure that the voltage level is safe, measure the mains input on Main Circuit
Card terminal block X1.
Dangerous external control voltages may be present on the relay output of the
Control Card. Always check for high voltage at X1 terminals 13-15, if they are
switching supply voltage.
Warning! When the ACS 200 is connected to the mains, the motor terminals U2, V2
and W2 are live even if the motor is not running. Do not make any connections when
the ACS 200 is connected to the mains. Disconnect and lock out mains to the frequency converter before servicing the unit. Failure to disconnect mains may cause
death or serious injury.

If a short time is entered for acceleration time in a system with high inertia, the
acceleration time will be limited by the I LIMIT parameter. Conversely, if a short time
is entered for deceleration time in such a system, the deceleration time will be
limited by the d.c. link bus regulator. In some cases, the motor will take a long time
to come to a stop. If the system inertia is high, an OVERVOLTAGE fault may occur if
the deceleration time is too small. The ACS 200 can deliver about 15 % dynamic
braking torque without an external braking resistor. If a short deceleration time is
31
Chapter 7 - Drive Parameters
critical to your application, we suggest you add a dynamic braking resistor (option)
to your system. The maximum (minimum) recommended acceleration (deceleration)
for the nominal size motor is 40 Hz per second. If the motor rating is less than the
nominal power of the ACS 200, smaller settings can be used.
If the reference signal changes at a slower rate than the acceleration or deceleration
time, the output frequency change will follow the reference signal. If the reference
signal changes faster than the acceleration or deceleration time, the output frequency change will be limited by the parameters.
FAULT MEMORY
NOM RPM
The ACS 200 continuously monitors itself for faulty operation. The last three faults
are stored in Page 1 parameter FAULT MEMORY. Refer to chapter 8 Fault Tracing,
page 42, for further information on fault memory.
Nominal motor rpm from the motor rating plate.
NOM FREQ
Nominal motor frequency from the motor rating plate (sometimes called the field
weakening point). The maximum output frequency of the ACS 200 is determined
according to the nominal motor frequency:
50-59 Hz => fMAX=120 Hz; 60-100 Hz => fMAX=180 Hz; 101-400 Hz => fMAX=500 Hz
NOM VOLT
Nominal motor voltage (from the motor rating plate). NOM VOLT sets the maximum
output voltage supplied to the motor by the ACS 200. NOM FREQ sets the frequency where the voltage to the motor is equal to NOM VOLT. With these two
parameters it is possible to adapt the ACS 200 to the motor.
ACS 200 cannot supply voltage to the motor greater than the mains voltage. When
driving a motor that has a nominal voltage lower than the supply voltage, it may not
be possible to drive the motor at full torque because of current limitations.

FLYING
Use this setting to start the motor if it may be already rotating, as in a fan drive. The
drive will start smoothly at the current frequency instead of starting at 0 Hz. By
selecting FLYING, the drive will be able to ride through short interruptions of the mains
supply.
Note! Flying start searches for the running speed by applying a small torque to the
load at the maximum frequency and decreasing the output frequency until the load
speed is found. If the motor is not coupled to a load or the load has low inertia, the
motor will start at a speed higher than the set reference.
Note! If the motor and load are rotating in a direction opposite to the commanded
rotation, the ACS 200 will start the motor from 0 Hz and accelerate according to the
selected acceleration ramp.
AUTO BOOST
Automatic start current boost, which may be necessary in drives with high starting
torque. Automatic torque boost is active only from 0 Hz to 20 Hz or until the reference speed is reached. Torque boost is not activated if the output frequency falls
below 20 Hz while running. See also Page 2 parameter IR COMPo

SWITCHf
The analogue output signal minimum can be set to 0 rnA or 4 rnA. The maximum
output remains 20 rnA. Selecting 4 rnA provides a "living zero" function. If a fault
occurs, the output current will drop to 0 rnA as an alternate fault indicator signal.
Motor noise can be minimised by adjusting the switching frequency to a ~alue that
does not create resonances in the motor system. The optimum switching frequency
is the lowest frequency where the noise is acceptable. This frequency may not be
the same for identical motor systems. As the switching frequency goes up, the
inverter efficiency goes down (refer to figure 2-1 on page 9), so it is best to use a
low switching frequency if the application can tolerate noise.
Note! At output frequencies less than 12 Hz, the switching frequency may be automatically reduced.
CRITf1L
CRITf1H
CRITf2L
CRITf2H
In some systems it may be necessary to avoid certain frequencies because of mechanical resonance problems. With these parameters it is possible to set up two
different frequency ranges that the ACS 200 will skip over. It is not necessary that,
for example, CRIT f2L be greater than CRIT f1 H, just as long as the LOW parameter
in one set is lower than the HIGH parameter in the same set. Sets may overlap, but
the skip will be from the lower LOW value to the higher HIGH value.
Example: Fan system with bad vibration from 18 Hz to 23 Hz and from 46 Hz to
52 Hz. Running speed set to 60 Hz with reference. Set the parameters as follows:
CRIT f1 L = 18 Hz;
GRIT f1 H = 23 Hz;
GRIT f2L = 46 Hz;
GRIT f2H = 52 Hz

Chapter 7 - Drive Parameters
The following is an altemate way to enter the LOW and HIGH settings for critical
frequency:
• Run the drive with extemal reference.
• Using the analogue input, set the frequency to the critical frequency LOW value.
• Go to parameter CRIT f1 L on Page 2.
• Press and hold the CIl key for three seconds.
• The ACS 200 will respond by updating the frequency setting to the current value.
The CRIT f1 L is now set.
• Increase the analogue input reference so that the output frequency is just above
the critical frequency span.
• Go to parameter CRIT f1 H on Page 2.
• Press and hold the CIl key for three seconds.
• The ACS 200 will respond by updating the frequency setting to the current value.
The CRIT f1 H is now set.
Repeat the procedure for the second critical frequency range if necessary. The
frequency values can be edited when the drive is stopped. To erase the critical
frequencies, set both to 0 Hz.
IR COMP
This parameter allows extra torque at speeds between 0.1 Hz and the nominal
motor speed. The parameter differs from the AUTO BOOST option of the START
parameter in that it is always valid in the 0.1 Hz to nominal motor speed range.
Keep the boost voltage as low as possible for the application, as the motor will
overheat rapidly or an overcurrent fault may occur if a high level of compensation is
applied.
Small motors can take higher compensation than larger motors because the winding
resistance is higher in small motors. If the motor must drive a load with a high starting torque, we recommend using AUTO BOOST starting. If the load torque is high
below the nominal motor frequency, use just enough IR compensation to drive the
load. If you have trouble with motor overheating, use a motor with more poles and
run at a higher frequency.
If the IR Compensation is set too high, the motor can "saturate" and will not rotate at
all, but will draw current.

DC-BRAKE
U1f RATIO
When the STOP parameter is set to DC BRAKE, this parameter sets the d.c. injection time in seconds. If the braking time is too short, the drive stops by coasting after
the d.c. braking time has elapsed.
The voltage to frequency ratio in the frequency range 0 Hz to nominal motor frequency can be set to either LINEAR, SQUARE or OPTIM.
LINEAR
The voltage of the motor changes linearly with frequency in the constant flux range.
Linear U/f (V/Hz) ratio is normally used in constant torque applications, or where the
torque characteristics of the load are linear with speed.
SQUARE
Squared U/f (V/Hz) ratio is normally used in applications where the torque characteristic of the load is proportional to the square of the speed, such as centrifugal pump
or fan systems.
OPTIM
The motor voltage is automatically controlled to minimise the motor losses and
noise. This setting is suitable for a drive which has a slowly changing load torque
and a motor which operates mainly below nominal load.
Note! Parameter MOTOR I must be set correctly for best results.
Note! OPTIM cannot be used in a system where two or more motors are connected
in parallel to one ACS 200.
RESTART #
Number of times the ACS 200 will automatically reset the fault and restart after any
of the following faults: Undervoltage, Overvoltage, Overcurrent, Low AI-Signal, Unit
Fault. For further information on fault tracing refer to chapter 8 Fault Tracing page

Chapter 7- Drive Parameters
TEMP LIM
The ACS 200 motor thermal protection (sometimes called 12t or solid state overload
protection) is activated using the TEMP LIM parameter. When set to OFF, the motor
overload protection is deactivated. The TEMP LIM and MOTOR I parameters define
the continuous safe operating area for the motor, as illustrated in.figure 7-6.

Figure 7-6. Motor thermal protection.
When the motor current exceeds the level determined by the safe operating area,
the ACS 200 will begin calculating excessive temperature rise in the motor. When
the ACS 200 has determined that the motor has exceeded it's allowable temperature rise, it will stop the motor, indicate a "MOTOR TEMP" fault and activate the fault
relay. The fault can be reset, when the motor has cooled down to a safe temperature. ACS 200 will continue to calculate the motor temperature even if the motor is
not running. If the ACS 200 is disconnected from the mains, the overload protection
calculation is reset,. and the motor is assumed to be at ambient.
The motor thermal protection functipn is designed to protect motors even at low
speeds by decreasing the allowable operating current. This is necessary as the
motor's cooling fan becomes less efficient at low speeds.
Motors have a specified constant torque operating range, which defines the minimum speed a motor can still be driven at rated current (and proVide constant
torque). This speed is typically stated as a ratio (I.e. 2:1, 4:1, etc.). This ratio can be
converted to the proper TEMP LIM entry by the following equation:
TEMP LIM (HZ) = NOM FREQ (HZ) / ratio
Example 1: The typical ratio for an lEG motor rated at 50 Hz is 5:4.
TEMP LIM (Hz) = 50 Hz! (5/4) = 40 Hz
Example 2: A 2 hp motor is installed with an AGS 201-2P7-3. The motor has a rated
current of 3.4 A (460 V, 60 Hz) and a speed range of 4: 1.
TEMP LIM (Hz) = 60 Hz /4= 15 Hz
This means the motor can draw full current down to 40 Hz (1) or 15 Hz (2), and still
haVe enough cooling efficiency to operate safely. Please consult the motor manufacturer for the correct speed ratio when applying the motor overload protection feature.
MOTOR I
Nominal motor current at full load as indicated on the motor rating plate. See U/f
RATIO, TEMP LIM and figure 7-6 above. This parameter does not need to be set if
TEMP LIM is set to OFF and OPTIM U/f RATIO is not used. MOTOR I does not
restrict the I LIMIT parameter.

8 Fault Tracing
This chapter describes the ACS 200 fault indications and fault memory. It also
explains how to trace faults.
Fault indications
The ACS 200 continuously monitors itself for faulty operation. If a fault condition
should arise, a fault indication is displayed, the fault LED illuminates and ACS 200
waits for the operator to acknowledge the fault before resuming operation.
Fault resetting
An active fault can be reset either by pressing the keypad C~D button, deactivating
the Start input (011) or switching the input voltage off for a while. If the fault has
been removed, the ACS 200 will resume normal operation. If the fault has not been
removed, the ACS 200 will trip again. For automatic fault reset, refer to parameter
RESTART # on page 39.
Note! If the Start command is active and the fault has cleared, fault resetting starts
the drive.
Some "faults require you to cycle the power off and on once before the fault can be
cleared. Proper fault reset action is given in table 8-1.
Fault memory
When a fault is detected, it is stored so that it can be reviewed at a later date. The
last three faults are stored in Page 1 parameter FAULT MEMORY. The faults can be
checked for trends that may be useful in preventing future faults. For example, if the
last two out of three faults were overvoltage trips, the deceleration time should be
longer or you should install a braking resistor.
Scrolling through the FAULT MEMORY does not erase the FAULT MEMORY. The
oldest resetted fault indication is automatically erased when a new fault occurs.
Note! Undervoltage fault is stored in FAULT MEMORY if the fault occurs and automatic restart (RESTART #) is off. If the automatic restart is on, the undervoltage
fault is not stored in the FAULT MEMORY unless the fault persists after restart.

(1) NO FAULT
This message only appears in the fault
memory.
(2) OVERVOLTAGE
DC bus voltage has exceeded 130 % nominal
voltage. Overvoltage is generally caused
when the motor runs as a generator in drives
where the load inertia is extremely high and
the deceleration time is set low.
• In case of temporary supply voltage peak,
reset and start.
• Use longer deceleration time or
• Use coasting stop function if it is compatible
with the application.
• If short deceleration time is needed, use
Dynamic Braking Resistor.
DC bus voltage has gone below 65 % of the
nominal voltage. Most common reason for low
voltage trip is failure in the mains supply, loss
of phase or "brown out" condition. Internal
failure in ACS 200 can also cause a low
voltage trip.
• In case of temporary supply voltage drop,
reset and start.
• Check mains input.
• If mains input is adequate, an internal failure
has occured. Contact the nearest ACS 200
supplier.
[Ci5]
(3) UNDERVOLTAGE
(4) OVERCURRENT ACS 200 has determined that the motor is
operating in the overcurrent region. The motor
is not turning because of increased load
torque. Motor may be too small for the application.
• Remove mechanical problem causing increased load torque.
• Check dimensioning, use larger ACS 200
and motor if necessary.
(5) LOW AI-SIGNAL
Analogue input less than 2 V/4 mA and minimum has been set to 2 V/4 mA or Analogue
Input less than selected "customised minimum".
• Input reference has failed or control cable is
broken. Check the reference circuit.
(6) PANEL COM
ERR
Control Panel was removed when control was
in Local mode. Due to safety reasons, the
drive stops in this fault condition.
• Attach the Control Panel and reset the fault,
then change to Remote mode and remove
Panel.
• Use remote (Wired) controls to reset the
fault, then start and run with remote controls.

Analogue input (AI)
An analogue input to the ACS 200 is for a user-supplied control signal. The signal
may be a speed reference or a process feedback. This signal can be:
• from a manual speed potentiometer
• DC voltage (0 (2) to 10 V d.c.)
• DC current (0 (4) to 20 mA d.c.)
Debus
Intermediate d.c. link where the input voltage is rectified and filtered. The d.c. bus
comprises:
• DC potential source (internal rectifier bridge)
• DC bus capacitors that provide filtration of the d.c. source potential and provide
some buffering between the d.c. source and the power inverter section.
Default
Value provided for a parameter as a part of the program when the ACS 200 is
started initially. The factory setting is the default.
Digital input (DI)
The digital inputs (01) receive bistable (two-state On-Off) control signals from the
outside world. An example of such would be a two-position Start-Stop selector
switch.
ESD
ESD is an acronym for Electrostatic Discharge. ESD warnings indicate situations in
which static electricity can damage circuit boards on the ACS 200. Follow the precautions listed in the Safety Instructions section at the beginning of this manual
when installing or removing circuit boards.
Field weakening point
Nominal motor frequency. This is the point at which the output voltage no longer
increases as the output frequency is increased. Operation above this point results in
reduced motor torque capability while the output kVA remains constant.
IGBT
An IGBT is a fast switching power transistor. ACS 200 frequency converters use
these in the inverter section as part of the process of changing d.c. voltage to a.c.
voltage.
IR compensation
IR compensation is voltage added to the normal motor voltage to compensate for
resistive losses in small motors. To realise acceptable starting and running torque at
low speeds it may be necessary to add some voltage to the normal voltage/frequency ratio of the drive. Refer to figure 7-5 on page 39.
Joystick control
Joystick control allows you to use a potentiometer for external speed and direction
drive control through analogue input A11.
Living zero
Setting the minimum value of the analogue input to 4 mA (2 V) provides the operator
a "living zero" function. The existence of a control signal can then be supervised by
setting the Page 2 parameter REF OFFSET to 2V4mA or JOYSTK 2V4mA, which
causes a fault indication if input is less than 4 mA (2 V). This option is also available
through the Page 2 parameter A. OUT OFFS.

Chapter 10 - Glossary
Memory
Place where data and instructions are stored for use by the program.
Parameter
A memory address that is used to store data for use by the program. The complete
table of parameters is presented in chapter 7 Drive Parameters page 29.
RFI
RFI is an acronym for Radio Frequency Interference; stray electromagnetic radiation
caused by rapidly changing current. The motor driving signals can create RFI problems if they are not shielded. These problems can interfere with radio and television
reception or other control equipment used in the vicinity of the ACS 200.
