Safety

Warning! The ACH550 adjustable speed AC drive should ONLY be installed by
a qualified electrician.

Warning! Even when the motor is stopped, dangerous volt age is present a t the
Power Circuit terminals U1, V1, W1 and U2, V2, W2 and, where present, UDC+,
UDC-, 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 removed from the input terminals of the
ACH550, there may be dangerous voltage (from external sources) on the
terminals of the relay outputs R01

Warning! When the control te rminals of two or mo re drive units 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 units or an external
supply.

…R03.

Warning! The ACH550-UH is not a field repairable unit. Never attempt to repair
a malfunctioning unit; contact the factory or your local Authorized Service
Center for replacement.

Warning! The ACH550 will start up automatically after an input voltage
interruption if the external run command is on.

Warning! The heat sink may reach a high temperature. See "Technical Data" on
page 225.

Warning! If the drive will be used in a floating network, remove screws at EM1
and EM3 (Frame size R1

2. Drill holes of appropriate size.

Note! Frame sizes R3 and R4 have four holes along the top. Use only two. If
possible, use the two outside holes (to allow room to remove the fan for
maintenance).

Note! ACH400 drives can be replaced using the original mounting holes. For R1 and
R2 frame sizes, the mounting holes are identical. For R3 and R4 frame sizes, the
inside mounting holes on the top of ACH550 drives match ACH400 mounts.

Installation

ACH550-UH User’s Manual 13

Wiring Overview

Warning! Ensure the motor is compatible for use with the ACH550. The
ACH550 must be installed by a competent person in accordance with the
considerations defined in

"Preparing for Installation" on page 8. If in doubt,

contact your local ABB sales or service office.

As you install the wiring, observe the following:

• There are two sets of wiring instructions – one set for each enclosure type (IP 21
/ UL type and IP 54 / UL type 12). Be sure to select the appropriate procedure.

• For the power connection points on the drive see the "Connection Diagrams"
section below.

• Use separate conduit runs to keep these three classes of wiring apart:
– Input power wiring.

– Motor wiring.
– Control/communications wiring.

• For details on power connections, refer to the following sections in "Technical
Data":

– "Input Power Connections" on page 228.
– "Motor Connections" on page 232.

• For floating networks (also known as IT, ungrounded, or high impedance
networks):

– Disconnect the internal RFI filter by removing both the EM1 and EM3 screws

(frame sizes R1…R4, see page

14), or F1 and F2 screws (frame sizes

R5…R6, see page 15).

– Do NOT install an external filter, such as one of the kits listed in the filter table

236. Using an EMC/RFI filter grounds the input power through the filter

on
capacitors, which could be dangerous and could damage the unit.

– Where EMC requirements exist, check for excessive emission propagated to

neighboring low voltage networks. In some cases, the natural suppression in
transformers and cables is sufficient. If in doubt, use a supply transformer with
static screening between the primary and secondary windings.

• For details on control connections, refer to the following sections:
– "Control Connections" on page 237.

– "Application Macros" starting on page 35.

• For electro-magnetic compliance (EMC), follow local codes and the requirements

"Motor Cable Requirements for CE & C-Tick Compliance" on page 234. For

in
example:

– Properly ground the wire screen cable shields.
– Keep individual un-screened wires between the cable clamps and the screw

terminals as short as possible.

– Route control cables away from power cables.

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 “S tart-Up by Changing
the Parameters Individually” on page 23.

• Press Enter to move to the following options:
– Select “Commission Drive” to commission the drive as described in section

“Start-Up by Using the Start-Up Assistant” on page 23.

– 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

27).

• Basic Control Panel: Refer to "Parameters Mode" on page 26, for parameter
editing instructions.

Installation

Macros

Note! Selecting the appropriate macro should be part of the original system design,
since the control wiring installed depends on the macro used.

ACH550-UH User’s Manual 21

1. Review the macro descriptions in "Application Macros" on page 35. 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 26, 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 "Parameter Descriptions" starting on page 51.
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 213 and 218 respectively, or

• Press the help key (Assistant Control Panel only) while fault or alarm is displayed.

3. Adjust the system or parameters as appropriate.

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

• The PARAMETER LOCK 1602

• The PARAM SAVE 1607

• Groups 50…52 serial communication parameters

• 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).

Floating Point

This application macro is for applications where speed reference needs to be
controlled through digital inputs (DI5 & DI6). By activating digital input 5, the speed
reference increases, by activating digital input 6, the speed reference decreases. If
both digital inputs are active or inactive, the reference does not change.

Note! When constant speed 1 is activated using digital input 3 (DI3), the reference
speed is the value of parameter 1202. The value remains as the reference speed
when digital input 3 is deactivated.

9910 MOTOR ID RUN 0, 1 1 0 9

This parameter controls a self-calibration process called the
Motor Id Run. During this process, the drive operates the
motor in order to identify it’s characteristics, and then
optimizes control by creating a motor model. This motor
model is especially effective when:

• Operation point is near zero speed.

• Operation requi res 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).

If no Motor Id Run is performed, the drive uses a less
detailed motor model created when the drive is first run. This
“First Start” model is updated automatically* after any motor
parameter is changed. To update the model, the drive
magnetizes the motor for 10 to 15 seconds at zero speed.
*Creating the “First Start model does require that either 9904

VECTOR: SPEED), or 9904 = 3 (SCALAR: FREQ) and

2101 = 3 (

BOOST).

To perform a Motor Id Run:

1. De-couple load from motor (or otherwise reduce
load to near zero).

2. Verify that motor operation is safe:

• The run automatically operates the motor in the

forward direction – confirm that forward rotation is
safe.

• The run automatically operates the motor at

50…80% of nominal speed – confirm that operation
at these speeds is safe.

3. Check following parameters (if changed from factory
settings):

• 2001

MINIMUM SPEED < 0

• 2002

MAXIMUM SPEED > 80% of motor rated speed.

• 2003

MAX CURRENT > 130% of I

• The maximum torque (parameters 2014, 2017 and/

or 2018) > 50%.

• Select Parameters

Group 17: Override

This group defines the source for the override activation signal, the override speed/
frequency and pass code and how the override is enabled and disabled.

When override DI is activated, the drive stops and then accelerates to the preset
speed or frequency. When the DI is deactivated the drive stops and reboots. If the
start command, run enable and start en ables are active in the AUTO mode the drive
starts automatically and continues normally af ter ove rride mode. In the HAND mode
the drive returns to OFF mode.

When override is active:

• Drive runs at preset speed

• Drive ignores all keypad commands

• Drive ignores all commands from communication links

• Drive ignores all digital inputs except override activation/deactivation, RUN
ENABLE and START ENABLE

• Drive displays alarm message “2020
