Safety
Use of warnings and notes
There are two types of safety instructions throughout this manual:
•Notes draw attention to a particular condition or fact, or give information on a
subject.
•Warnings caution you about conditions which can result in serious injury or death
and/or damage to the equipment. They also tell you how to avoid the danger. The
warning symbols are used as follows:
Electricity warning warns of hazards from electricity which can cause physical
injury and/or damage to the equipment.
General warning warns about conditions, other than those caused by electricity,
which can result in physical injury and/or damage to the equipment.
WARNING! The ACH550 adjustable speed AC drive should ONLY be installed by a
qualified electrician.
WARNING! Even when the motor is stopped, dangerous voltage is present at the
power circuit terminals U1, V1, W1 (L1, L2, L3) and U2, V2, W2 (T1, T2 T3) and,
depending on the frame size, UDC+ and UDC-, or BRK+ and BRK-.
WARNING! Dangerous voltage is present when input power is connected. After
disconnecting the supply, wait at least 5 minutes (to let the intermediate circuit
capacitors discharge) before removing the cover.
WARNING! Even when power is switched off from the input terminals of the
ACH550, there may be dangerous voltage (from external sources) on the terminals
of the relay outputs.
WARNING! When the control terminals of two or more drives are connected in
parallel, the auxiliary voltage for these control connections must be taken from a
single source which can either be one of the drives or an external supply.
Safety
1-4ACH550-UH User’s Manual
WARNING! Disconnect the internal EMC filter when installing the drive on an IT
system (an ungrounded power system or a high-resistance-grounded [over 30 ohm]
power system).
WARNING! Do not attempt to install or remove EM1, EM3, F1 or F2 screws while
power is applied to the drive’s input terminals.
WARNING! Do not control the motor with the disconnecting device (disconnecting
means); instead, use the control panel keys or commands via the I/O board of the
drive. The maximum allowed number of charging cycles of the DC capacitors (i.e.
power-ups by applying power) is five in ten minutes.
WARNING! Never attempt to repair a malfunctioning ACH550; contact the factory or
your local Authorized Service Center for repair or replacement.
WARNING! The ACH550 will start up automatically after an input voltage
interruption if the external run command is on.

Start-up
The ACH550 has default parameter settings that are sufficient for many situations.
However, review the following situations. Perform the associated procedures as
appropriate.
Spin motor
When first installed and started the control panel displays a welcome screen with the
following options.
•Press Exit to commission the drive as described in section Start-up by changing
the parameters individually on page 1-47.
•Press Enter to move to the following options:
– Select “Commission Drive” to commission the drive as described in section
Start-Up by Start-up by using the Start-Up Assistant on page 1-47.
– Select “Spin Motor” to operate the motor prior to commissioning. This option
operates the motor without any commissioning, except entry of the motor data
as described below. Spin Motor is useful, for example, to operate ventilation
fans prior to commissioning.
Note: When using Spin Motor, the motor speed is limited to the range 1/3…2/3 of
maximum speed. Also, no interlocks are activated. Finally, once the drive is
commissioned, the welcome screen and this option no longer appear.
Motor data
The motor data on the ratings plate may differ from the defaults in the ACH550. The
drive provides more precise control and better thermal protection if you enter the
rating plate data.
1. Gather the following from the motor ratings plate:
•Voltage
•Nominal motor current
•Nominal frequency
•Nominal speed
•Nominal power
2. Edit parameters 9905…9909 to the correct values.
•Assistant Control Panel: The Start-Up Assistant walks you through this data entry
(see page 1-37).
•Basic Control Panel: Refer to Parameters Mode on page 1-35, for parameter
editing instructions.
Installation
ACH550-UH User’s Manual1-31
Macros
Note: Selecting the appropriate macro should be part of the original system design,
since the control wiring installed depends on the macro used.
1. Review the macro descriptions in Application macros on page 1-49. Use the macro
that best fits system needs.
2. Edit parameter 9902 to select the appropriate macro. Use either of the following:
•Use the Start-up Assistant, which displays the macro selection immediately after
motor parameter setup.
•Refer to Parameters Mode on page 1-35, for parameter editing instructions.
Tuning – parameters
The system can benefit from one or more of the ACH550 special features, and/or
fine tuning.
1. Review the parameter descriptions in Complete parameter descriptions starting on
page 1-80. Enable options and fine tune parameter values as appropriate for the
system.
2. Edit parameters as appropriate.
Fault and alarm adjustments
The ACH550 can detect a wide variety of potential system problems. For example,
initial system operation may generate faults or alarms that indicate set-up problems.
1. Faults and alarms are reported on the control panel with a number. Note the number
reported.
2. Review the description provided for the reported fault/alarm:
•Use the fault and alarm listings on pages 1-282 and 1-288 respectively, or
•Press the help key (Assistant Control Panel only) while fault or alarm is displayed.
3. Adjust the system or parameters as appropriate.

•One to three parameter values – The default display shows
parameters 0103 (OUTPUT FREQ) in percentages, 0104
(CURRENT) in amperes and 0120 (AI1) in milliamperes.
Control panel
– Use parameters 3401, 3408, and 3415 to select the parameters (from Group
01) to display. Entering “parameter” 0100 results in no parameter displayed.
For example, if 3401 = 0100 and 3415 = 0100, then only the parameter
specified by 3408 appears in the Control Panel display.
ACH550-UH User’s Manual1-35
– You can also scale each parameter in the display, for example, to convert the
motor speed to a display of conveyor speed. Parameters 3402…3405 scale
the parameter specified by 3401, parameters 3409…3412 scale the parameter
specified by 3408, etc.
•A bar meter rather than one of the parameter values.

Handling inexact downloads
In some situations, an exact copy of the download is not appropriate for the target
drive. Some examples:
•A download to an old drive specifies parameters/values that are not available on
the old drive.
•A download (from an old drive) to a new drive does not have definitions for the
new parameters – parameters that did not originally exist.
•A download can include an illegal value for the target drive, e.g. a backup from a
small drive can have a switching frequency of 12 kHz whereas a big drive can
only handle 8k Hz.
As a default, the control panel handles these situations by:
•Discarding parameters/values not available on
the target drive.
•Using parameter default values when the
download provides no values or invalid values.
•Providing a Differences List – A listing of the
type and number of items that the target cannot
accept exactly as specified.
You can either accept the default edits by pressing
READY, or view and edit each item as follows:
1. Highlight an item type in the Differences List (left screen below) and press SEL to
see the details for the selected type (right screen below).
Control panel
ACH550-UH User’s Manual1-43
In the above-right “details” screen:
•The first item that requires editing is automatically highlighted and includes
details: In general, the first item listed in the details is the value defined by the
backup file. The second item listed is the “default edit.”
•For tracking purposes, an asterisk initially appears by each item. As edits are
made, the asterisks disappear.
2. In the illustrated example, the backup specifies a switching frequency of 12 kHz, but
the target drive is limited to 8 kHz.
3. Press EDIT to edit the parameter. The display is the target drive’s standard edit
screen for the selected parameter.
4. Highlight the desired value for the target drive.
5. Press SAVE to save setting.
6. Press EXIT to step back to the differences view and continue for each remaining
exception.
7. When your editing is complete, press READY in the Differences List and then select
“Yes, save parameters.”
Download failures
In some situations, the drive may be unable to accept a download. In those cases,
the control panel display is: “Parameter download failed” plus one of the following
causes:
•Set not found – You are attempting to download a data set that was not defined in
the backup. The remedy is to manually define the set, or upload the set from a
drive that has the desired set definitions.
•Par lock – The remedy is to unlock the parameter set (parameter 1602).
•Incompat drive/model – The remedy is to perform backups only between drives of
the same type (ACS/industrial or ACH/HVAC) and the same model (all ACH550).
•Too many differences – The remedy is to manually define a new set, or upload the
set from a drive that more closely resembles the target drive.
Note: If upload or download of parameters is aborted, the partial parameter set is not
implemented.
Clock Set Mode
The Clock Set Mode is used for setting the time and date for the internal clock of the
ACH550. In order to use the timer functions of the ACH550, the internal clock has to
be set first. Date is used to determine weekdays and is visible in Fault logs.

Application macros
Overview
Macros change a group of parameters to new, predefined values designed for
specific applications. Use macros to minimize the need for manual editing of
parameters. Selecting a macro sets all other parameters to their default values,
except:
•Group 99: Start-up Data parameters (except parameter 9904)
•Group 29: Maintenance triggers
After selecting a macro, additional parameter changes can be made manually using
the control panel.
Application macros are enabled by setting the value for parameter 9902
MACRO. By default, HVAC Default (value 1) is the enabled macro.
APPLIC
General considerations
The following considerations apply for all macros:
•When using a direct speed reference in AUTO mode, connect the speed
reference to analog input 1 (AI1), and provide the START command using digital
input 1 (DI1). In HAND/OFF mode, the control panel provides the speed
reference and START command.
•When using process PID, connect the feedback signal to analog input 2 (AI2). As
a default, the control panel sets the Setpoint, but analog input 1 can be used as
an alternate source. You can set up process PID using parameters (Group 40) or
using the PID control assistant (recommended).

9910 ID RUN0, 110 (
OFF/IDMAGN)
This parameter controls a self-calibration process called the Motor ID Run. During this process, the drive operates
the motor (motor rotating) and makes measurements in order to identify motor characteristics and create a model
used for internal calculations. An ID Run is especially effective when:
• vector control mode is used [parameter 9904 = 1 (
VECTOR:SPEED) or 2 (VECTOR:TORQ)], and/or
• operation point is near zero speed, and/or
• operation requires a torque range above the motor nominal torque, over a wide speed range, and without any
measured speed feedback (i.e. without a pulse encoder).
OFF/IDMAGN – The Motor ID Run process is not run. Identification magnetization is performed, depending on
0 =
parameter 9904 and 2101 settings. In identification magnetization, the motor model is calculated at first start by
magnetizing the motor for 10 to 15 s at zero speed (motor not rotating). The model is recalculated always at start
after motor parameter changes.
• Parameter 9904 = 1 (
• Parameter 9904 = 3 (
VECTOR:SPEED) or 2 (VECTOR:TORQ): Identification magnetization is performed.
SCALAR:FREQ) and parameter 2101 = 3 (SCALARFLYST) or 5 (FLY + BOOST): Identification
magnetization is performed.

SCALAR:FREQ) and parameter 2101 has other value than 3 (SCALARFLYST) or 5 (FLY +
completion, this value automatically changes to 0.
Note: The motor must be de-coupled from the driven equipment.
Note: If motor parameters are changed after ID Run, repeat the ID Run.
WARNING! The motor will run at up to approximately 50…80% of the nominal speed during the ID Run.
The motor will rotate in the forward direction.
Ensure that it is safe to run the motor before performing the ID Run!
