• conduit box

•screws

• cover The kit is included with IP 21 / UL type 1 Enclosures.

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.
