Safety

WARNING! All electrical installation and maintenance work on the drive

should be carried out by qualified electricians only.

WARNING! The drive and adjoining equipment must be properly

grounded.

WARNING! Do not attempt any work on a powered drive. After

switching off the mains, always allow the intermediate circuit capacitors

5 minutes to discharge before working on the drive, the motor or the

motor cable. It is good practice to check (with a voltage indicating

instrument) that the drive is in fact discharged before beginning work.

WARNING! The motor cable terminals of the drive are at a dangerously

high voltage when mains power is applied, regardless of motor

operation.

WARNING! There can be dangerous voltages inside the drive from

external control circuits even when the drive mains power is shut off.

Exercise appropriate care when working on the unit. Neglecting these

instructions can cause physical injury or death.

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:

Dangerous voltage warning warns of high voltage which can cause

physical injury and/or damage to the equipment.

Preparing for Installation

The OTAC-01 Module

The OTAC-01 Pulse Encoder Interface module is an interface for

connecting a digital pulse encoder to an ACS550 drive. A pulse

encoder should be used if accurate speed or position (angle) feedback

from the motor shaft is required.

Module Layout

Compatibility

The OTAC-01 module is compatible with all ACS550 drives. To confirm

compatibility with a particular pulse encoder, compare the pulse

encoders requirements to the “Specifications” on page 19.

Mounting

WARNING! Follow the safety instructions given in this guide and in the

ACS550 User’s Manual.

To mount the OTAC-01 module:

1. If not already off, remove mains power from the drive.

2. Remove the drive cover. (See instructions in the drive User’s Manual.)

3. Insert the OTAC-01 module’s

plastic hooks into the front of

the drive at SLOT 1.

4. Carefully fit the connector at

the other end of the module

into the drive connector.

5. Press until the retaining clip

locks the module into position.

NOTE! Signal and power

connections to the drive are

automatically made through a

6-pin connector.

6. Connect the ground lead to

the chassis screw terminal on the drive.

Installation

NOTE! Correct installation of the ground lead is essential for fulfilling

the EMC requirements and for proper operation of the module.

Installation

Wiring – The Encoder Power

The OTAC-01 module does not supply power for the encoder. An

external power supply (as diagrammed below) is recommended. The

drive’s 24 VDC supply from terminals X1:10 and X1:11 can be used if

the total draw on the supply does not exceed 250 mA. Use the following

table to determine if the drive’s supply can be used.

1. Connect as follows:

Wiring – The Encoder

1. Determine the encoder wiring configuration:

• Refer to “Phasing” on page 8 to determine if the encoder has normal

pulse order – encoder channel A/1 pulse leads channel B/2 pulse.

• Refer to “Encoder Output Types” on page 9 to determine the

encoder’s output type.

• For push-pull types, refer to the manufacturer’s recommendation for

connection – either single-ended or differential can be used.

2. Refer to “Wiring Diagrams” on page 10, select the appropriate diagram,

and wire the encoder.

Installation

Note: Normally, ground the cable shield only at the drive end. However,

if the encoder is isolated from the motor, and from ground, then connect

the cable shields to both the OTAC module and the encoder housing.

Note: Do not route the encoder cables parallel to power (e.g. motor)

cables.

3. Verify correct encoder phasing. See options below.

Phasing

When the encoder is connected correctly, running the drive in the

Forward (positive speed reference) direction should produce a positive

encoder speed feedback.

Option A: Oscilloscope Test. On incremental encoders, the two

output channels, usually marked A and B or 1 and 2, are 90° (electrical)

apart from each other. When rotated clockwise, most encoders – but

not all – have channel A/1 leading channel B/2 as illustrated below.

Determine the leading channel by referring to the encoder

documentation or by measuring with an oscilloscope.

The encoder output channel that leads when the drive runs Forward

should be connected to OTAC terminal A. The output channel that trails

should be connected to OTAC terminal B.

Option B: Functional Test. For this test:

• Temporarily, switch the drive to scalar mode (parameter 9904 = 3), if

not already there.

Connect the zero reference output

channel (usually marked 0, N or Z)

only if parameter 5010 ZPLS ENABLE =

1 (ENABLE).

Installation

• Run the drive in the forward direction.

• Verify that parameter 0147 MECH REVS is increasing in the positive

direction.

• If not, switch the A/A (or 1/1) connections.

Wiring Diagrams

Push-Pull Type Encoder Output

Diagram assumes normal pulse order in Forward rotation: Pulse A/1 leads as

diagrammed below

For encoders with pulse 2 leading, change diagram for these connections:

• Encoder A/1 and B/2 should be wired to OTAC terminals B and A respectively.

• Encoder A/1 and B/2 (if present) should be wired to OTAC terminals B and A

respectively.
