1-4 Getting Started

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 power from the PowerFlex drive, and then verify power has been discharged before installing or removing an adapter.

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 an adapter. Failure to comply may result in injury and/or equipment damage.

ATTENTION: Risk of equipment damage exists. The adapter 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 adapter. If you are unfamiliar with static control procedures, refer to Guarding Against Electrostatic Damage (publication 8000-4.5.2).

ATTENTION: Risk of injury or equipment damage exists. If the adapter is transmitting control I/O to the drive, the drive may fault when you reset the adapter. Determine how your drive will respond before resetting an adapter.

ATTENTION: Risk of injury or equipment damage exists.

Parameter 02 - [Comm Loss Action] lets you determine the action of the adapter and connected drive if communications are disrupted. By

default, this parameter faults the drive. You can set this parameter so that the drive continues to run. Precautions should be taken to ensure that the setting of this parameter does 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).

ATTENTION: Risk of injury or equipment damage exists. Parameter 03 - [Comm Loss Time] lets you determine how long it will take the adapter to detect network communication losses. By default, this parameter sets the timeout to ten seconds. You can set it so that the duration is shorter, longer, or disabled. When set to disabled, this also disables adapter Parameter 02 - [Comm Loss Action]. Therefore, a communications fault action will be ignored. Take precautions to ensure that the setting does 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).

Getting Started	1-5

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.

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.

Connecting the Drive/Adapter to the Network	2-11

Preparing for an Installation

Before installing the adapter, verify that you have all required equipment. Refer to Required Equipment on page 1-3.

Commissioning the Adapter

To commission the adapter, you must set a unique MAC address and, depending on where the PowerFlex drive node is located on the network (starting and ending network nodes versus all other node locations), appropriately set the TERM, -BIAS, and +BIAS switches.

Important: New settings are recognized only when power is applied to the adapter or it is reset. If you change a switch setting, cycle power or reset the adapter to apply the change.

		ATTENTION: Risk of equipment damage exists. The adapter
	!	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 adapter. If you are
		unfamiliar with static control procedures, refer to Guarding Against
		Electrostatic Damage (publication 8000-4.5.2).

2-2 Installing the Adapter

Setting the MAC Address

Set the MAC address using the MAC Address switches (Figure 2.1). Refer to Table 2.A for specific MAC address switch settings.

Important: Each node on the network must have a unique MAC address. Set the MAC address before power is applied because the adapter uses the MAC address it detects when it first receives power. To change a MAC address, you must set the new value. Then remove and reapply power to (or reset) the adapter.

Setting the TERM, -BIAS, and +BIAS Switches

The adapter’s TERM, -BIAS, and +BIAS switches (Figure 2.2) are used to turn on/off its built-in termination resistor and bias resistors.

Switches	Description	Default
SW1	Turns on/off the termination resistor	Up (Off)
SW2	Turns on/off the -bias resistor	Up (Off)

SW4	Reserved (not used)	—

Since nodes on a BACnet MS/TP network are typically a mix of Allen-Bradley PowerFlex drives and other brands of building automation products, the network node locations for the PowerFlex drives will determine how their adapter’s TERM, -BIAS, and +BIAS switches should be set.

Network with PowerFlex Drives at Starting and/or Ending Nodes

For a network with PowerFlex drives at the starting and/or ending nodes (Figure 2.3), set their 22-COMM-B adapter’s TERM, -BIAS, and +BIAS switches to the “Down” (On) position. All other PowerFlex drive network nodes must have these switches set to the “Up” (Off) position.

Network with PowerFlex Drives at Other Nodes

For a network with PowerFlex drives at other node locations—not starting and/or ending nodes (Figure 2.4), set their 22-COMM-B adapter’s TERM, -BIAS, and +BIAS switches to the “Up” (Off) position. In this network scenario, other brands of building automation products at the starting and/or ending nodes require appropriate termination and bias resistors. Refer to their documentation for details.

2-6 Installing the Adapter

Connecting the Adapter to the Drive

PowerFlex 40 Frames B and C, and PowerFlex 400 Frame C

1.Remove power from the drive, and remove the drive cover.

2.Use static control precautions.

3.Mount the adapter on the required special drive cover (ordered separately; see Figure 2.5 for part numbers).

•Frame B: Do not use the adapter screw; snap the adapter in place.

•Frame C: Use the adapter screw to secure the adapter to the cover.

Important: To properly ground the adapter in Frame B drives, install the special drive cover onto the drive using both cover fasteners. To ground the adapter in Frame C drives, tighten the adapter’s lower left screw (see Figure 2.5). In either case, tighten the screw(s) to the recommended torque (0.9 N•m / 8.0 lb•in).
