1-6 Getting Started

Benefits of Multi-Drive mode include:

• Lower hardware costs. Only one 1769-SM2 is needed for up to five

PowerFlex 4-Class drives per channel (15 total).

• Controller can independently control, monitor, and read/write

parameters for all five drives on each channel (same functionality as Single mode).

The trade-offs of Multi-Drive mode include:

• Since the RS-485 ports are used for daisy-chaining the drives,

additional DSI peripheral devices cannot be used with the drives. This includes an optional, external PowerFlex 4-Class HIM (22-HIM-A3 or 22-HIM-C2S) or a 22-SCM-232 Serial Converter module with a software tool. The AK-U0-RJ45-SC1 DSI Splitter cable cannot be used to add a second connection for a DSI peripheral device.

Compatible Products

The 1769-SM2 module is compatible with Allen-Bradley PowerFlex 4-Class (Component class) drives and other products that support DSI. At the time of publication, compatible products include:

• PowerFlex 4 drives

• PowerFlex 4M drives

• PowerFlex 40 drives

• PowerFlex 40P drives

• PowerFlex 400 drives

When the 1769-SM2 is used in Multi-Drive as a Modbus RTU Master, other Modbus RTU Slave devices, such as PowerFlex 7-Class drives with 20-COMM-H RS485 HVAC adapters, can also be connected.

Safety Precautions

Please read the following safety precautions carefully.

ATTENTION: Risk of injury or death exists. The PowerFlex drive may contain high voltages that can cause injury or death. Remove all

power from the PowerFlex drive, and then verify power has been removed before installing or removing the module.

ATTENTION: Risk of injury or equipment damage exists. Only personnel familiar with drive and power products and the associated

machinery should plan or implement the installation, start-up, configuration, and subsequent maintenance of the product using the module. Failure to comply may result in injury and/or equipment damage.

ATTENTION: Risk of injury or equipment damage exists. If the module is transmitting control I/O to the drive, the drive may fault when

you reset the module. Determine how your drive will respond before resetting the module.

ATTENTION: Risk of injury or equipment damage exists. When a system is configured for the first time, there may be unintended or

incorrect machine motion. Disconnect the motor from the machine or process during initial system testing.

1-8 Getting Started

ATTENTION: Risk of injury or equipment damage exists. Parameters 04 - [Idle Action 1], 19 - [Idle Action 2], and 34 - [Idle

Action 3] let you determine the action of the module and connected

drives if communications are disrupted. By default, these parameters fault the drive. You can set these parameters so that the drive continues to run. Precautions should be taken to ensure that the settings of these parameters do not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected cable or a faulted controller).

ATTENTION: Risk of injury or equipment damage exists. The examples in this publication are intended solely for purposes of

example. There are many variables and requirements with any application. Rockwell Automation, Inc. does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication.

ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II

applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating.

This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance.

This equipment is supplied as “open type” equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.

See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure. Also, see the appropriate sections in this publication, as well as the Allen-Bradley publication 1770-4.1 (“Industrial Automation Wiring and Grounding Guidelines”), for additional installation requirements pertaining to this equipment.

Preparing for an Installation

Consider the following when installing the 1769-SM2 module:

• Verify that you have all required equipment. Refer to Required

Equipment on page 1-6.

• A MicroLogix 1500 Base Unit or Compact I/O power supply has

limits in the amount of +5V dc and +24V dc current it can supply to modules in its I/O bank. These limits depend on the catalog number (e.g. 1769-PA2) of the power supply. A bank of modules must not exceed the current limits of the MicroLogix 1500 Base Unit or I/O bank power supply.

Refer to the MicroLogix 1500 User Manual (publication 1764-UM001) or the Compact 1769 Expansion I/O Power Supplies Installation Instructions (publication 1769-5.14).

• The module has a distance rating of four. Therefore, the module must

be within four modules of the I/O bank’s power supply.

2-2 Installing the Module

ATTENTION: Risk of equipment damage exists. The 1769-SM2 module contains ESD (Electrostatic Discharge) sensitive parts that can

be damaged if you do not follow ESD control procedures. Static control precautions are required when handling the module. If you are unfamiliar with static control procedures, refer to Guarding Against Electrostatic Damage (publication 8000-4.5.2).

Removing Power

ATTENTION: Risk of equipment damage exists. Remove power before installing or removing the 1769-SM2 module. When you install

or remove the module with power applied, an electrical arc may occur. An electrical arc can cause personal injury or equipment damage by:

• Sending an erroneous signal to your system’s field devices, causing

unintended machine motion.

• Causing an explosion in a hazardous environment.

Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance.

Installing the Module 2-3

Setting the Configuration Mode Switch

Before installing the module, make sure its Configuration Mode Switch is correctly set. See Configuration Methods on page 3-3 for details on the Controller and Parameter configuration modes. Then set the Configuration Mode Switch (SW1 in Figure 2.1

Figure 2.1 Configuration Mode and Single/Multi-Drive Operation Switch Locations

) for your application.

SW1 Setting Description

CONT (Controller) back position

PARAM (Parameter) front position

Default setting—The 1769-SM2 module uses the configuration data downloaded from the controller on power-up and when the controller is placed in run mode.

The 1769-SM2 module uses its internal parameter settings to configure the module.

2-4 Installing the Module

Setting the Operating Mode Switch (Single/Multi-Drive)

Before installing the module, set its Operating Mode Switch (SW2 in

Figure 2.1) for Single or Multi-Drive operation. All channels (CH1,

CH2, and CH3) will operate in the selected mode.

SW2 Setting Description

1X (Single mode) back position

5X (Multi-Drive mode) front position

Default setting — sets the 1769-SM2 module for Single mode using a single drive connection (one drive per channel).

Important: In Single mode, only one drive can be connected per channel. Connections to multiple drives must be removed since all powered and connected hosts will respond to any message sent by the module.

Sets the 1769-SM2 module for Multi-Drive mode using up to five PowerFlex 4-Class drives per channel.

In Multi-Drive mode, DSI peripherals such as the 22-HIM-A3 /

-C2S Human Interface Module, 22-SCM-232 serial converter, etc. CANNOT be used. They will not operate with the 1769-SM2 module or drives.

The specific number of drives used in Multi-Drive mode for each channel and a unique address for each drive must be configured using 1769-SM2 module parameters. For instructions, see

Setting the I/O Configuration (Multi-Drive Mode Only) page 3-14 and Setting Drive Node Addresses (Multi-Drive Mode Only) on page 3-16.

NOTE: In Multi-Drive mode, each channel can be independently configured for Modbus RTU Master operation by setting the respective channel’s [DSI I/O Cfg] parameter to “5” (RTU Master). This enables up to 31 RTU slave devices, such as PowerFlex 7-Class drives with 20-COMM-H RS485 HVAC adapters to be connected to that channel.

Important: A new switch setting is recognized only when power is

applied to the module, or the module is reset. If you change a setting, cycle power or reset the module.

The Configuration Mode Switch (SW1) and Operating Mode Switch (SW2) settings can be verified by respectively viewing module Parameters 01 - [Config Mode] and 02 - [DSI Mode] using an optional, external PowerFlex 4-Class HIM, DriveExplorer software or DriveExecutive software.

Installing the Module 2-5

Assembling the Module to the Controller

The 1769-SM2 module can be attached to adjacent controller modules before or after mounting. For mounting instructions, see Panel

Mounting on page 2-6 or DIN Rail Mounting on page 2-8. To work with

a system that is already mounted, see Replacing the Module within a

System on page 2-9.

Figure 2.2 and the following procedure describes how to assemble the

Compact I/O system.

Figure 2.2 Assembling 1769-SM2 Module to Compact I/O System

1. Disconnect power.

2. Check that the bus lever (A) of the 1769-SM2 module is in the

unlocked (fully right) position.

3. Use the upper and lower tongue-and-groove slots (B) to secure the

modules together.

4. Move the 1769-SM2 module back along the tongue-and-groove slots

until the bus connectors (C) line up with each other.

5. Use your fingers or a small screwdriver to push the bus lever back

slightly to clear the positioning tab (D).

6. Move the 1769-SM2 module’s bus lever fully to the left (E) until it

clicks. Ensure it is locked firmly in place.

ATTENTION: Risk of equipment damage exists. When attaching the 1769-SM2 module to a Compact I/O system, it is very important that

the bus connectors are securely locked together to ensure proper electrical connection. Failure to do this may cause an electrical arc, which can cause personal injury or equipment damage.

2-6 Installing the Module

7. Attach an end cap terminator (F) to the last module in the system by

using the tongue-and-groove slots as before.

8. Lock the end cap bus terminator (G).

Important: A 1769-ECR or 1769-ECL right or left end cap must be

Panel Mounting Procedure Using Module as a Template

The following procedure enables you to use the assembled modules as a template for drilling holes in the panel. Due to module mounting hole tolerance, it is important to follow these steps:

1. On a clean work surface, assemble no more than three modules.

2. Using the assembled modules as a template, carefully mark the

center of all module-mounting holes on the panel.

3. Return the assembled modules to the clean work surface, including

any previously mounted modules.

4. Drill and tap the mounting holes for the recommended M4 or #8

screw (not included).

5. Place the modules back on the panel, and check for proper hole

alignment.

6. Attach the modules to the panel using the mounting screws.

DIN Rail Mounting

The 1769-SM2 module can be mounted using these DIN rails:

• 35 x 7.5 mm (EN 50 022 - 35 x 7.5)

• 35 x 15 mm (EN 50 022 - 35 x 15)

When mounting the module to a DIN rail, make sure that the latches are closed and properly securing the module.
