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 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 electrostatic discharge (ESD) 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, see Guarding Against Electrostatic Damage, publication 8000-4.5.2.

ATTENTION: Risk of injury or equipment damage exists. DPI or SCANport host products must not be directly connected together using 1202 cables. Unpredictable behavior due to timing and other internal procedures can result if two or more devices are connected this way.

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.

Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action] let you determine the action of the adapter and connected drive if I/O communication is disrupted or the controller is idle. By default, these parameters fault the drive. You can set these parameters so that the drive continues to run, however, precautions should be taken to verify 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. 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 does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication.

2-2 Installing the Adapter

Commissioning the Adapter To commission the adapter, set the Rack Address Rotary Switches and the Configuration DIP Switches. Either set these switches to the desired settings or disable them by sliding Configuration DIP Switches SW7 and SW8 to the ‘On’ position so that adapter parameters can be used instead.

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

!

!

ATTENTION: Risk of equipment damage exists. The adapter contains electrostatic discharge (ESD) sensitive parts that can be damaged if you do not follow ESD control procedures. Static control precautions are required wh en handling the adapter. If you are unfamiliar with static control procedures, see Guarding Against Electrostatic Damage, publication 8000-4.5.2.

ATTENTION: Risk of equipment damage exists. Pen ink or pencil lead may damage the adapter switches. Do not use a pen or pencil to set the switches.

Setting the Rack Address Rotary Switches

The adapter accepts a rack address between 00 and 77 octal. The default setting is 01. See Table 3.A on page 3-3 to determine the decimal equivalent of the octal address to be used. Set the Rack Address Rotary Switches (Figure 2.1) to the octal address. The address is entered and displayed as an octal value, but is internally converted to a decimal address. Each Remote I/ O device must have a unique rack address that the controller can recognize. Note the following points:

•Although the adapter supports rack addresses up to 77 octal, not all controllers recognize all of the addresses, and a Remote I/O channel can support only 32 devices.

•If Configuration DIP Switches SW7 and SW8 are both set to ‘On’, the adapter uses the decimal rack address set in Parameter 3 - [RIO Addr Cfg]. See Setting the Rack Address on page 3-3.

•PLC-2 controllers identify rack addresses differently than other controllers. PLC-2 controllers identify the adapter rack address as one plus the value of the switch settings.

2-10 Installing the Adapter

Configuring and Verifying Key Drive Parameters

The PowerFlex 7-Class drive can be separately configured for the control and Reference functions in various combinations. For example, you could set the drive to have its control come from a peripheral or terminal block with the Reference coming from the network. Or you could set the drive to have its control come from the network with the Reference coming from another peripheral or terminal block. Or you could set the drive to have both its control and Reference come from the network.

The following steps in this section assume that the drive will receive the Logic Command and Reference from the network.

1.Use drive Parameter 090 - [Speed Ref A Sel] to set the drive speed Reference to ‘22’ (DPI Port 5).

2.If hard-wired discrete digital inputs are not used to control the drive, verify that unused digital input drive Parameters 361 - [Dig In1 Sel] and 362 - [Dig In2 Sel] are set to ‘0’ (Not Used).

3.Verify that drive Parameter 213 - [Speed Ref Source] is reporting that the source of the Reference to the drive is ‘22’ (DPI Port 5).

This ensures that any Reference commanded from the network can be monitored by using drive Parameter 002 - [Commanded Speed]. If a problem occurs, this verification step provides the diagnostic capability to determine whether the drive/adapter or the network is the cause.

TIP: For PowerFlex 750-Series drives, use drive Parameter 545 - [Speed Ref A Sel] to set the drive speed Reference:

a.Set the Port field to ‘Port 0 - PowerFlex 75x’.

b.Set the Parameter field to point to the port in which the 20-COMM-R adapter/20-750-20COMM Communication Carrier Card are installed (for example, ‘876 - Port 6 Reference’).

The number ‘876’ in the Parameter field of the example is the parameter in the drive that points to the port.

	Configuring the Adapter	3-3
Setting the Rack Address	If adapter Configuration DIP Switches SW7 and SW8 (Figure 2.2) are both

set to ‘On’, the value of Parameter 03 - [RIO Addr Cfg] determines the rack address. Note these points:

• Although the adapter supports rack addresses between 00 and 77 octal, not all controllers recognize all of the addresses, and a Remote I/O channel can support only 32 devices.

• PLC-2 controllers identify rack addresses differently than other controllers. PLC-2 controllers identify the adapter rack address as one plus the value of the parameter setting.

1.See Table 3.A to determine the decimal equivalent of the octal address to be used.

The rack address must be unique.

Table 3.A Rack Addresses (Decimal Equivalent versus Octal)

Decimal		Octal			Decimal	Octal			Decimal	Octal			Decimal	Octal
0		0		16		20		32		40		48		60
1	(Default)1		17	21			33	41			49	61
2	2			18		22		34		42		50		62

2.Set the value of Parameter 03 - [RIO Addr Cfg] to the decimal equivalent of the octal address to be used.

The address is entered and displayed as a decimal value, but is internally converted to an octal address.

Important: The HIM and software tools, such as DriveExplorer or DriveExecutive, will display the address as a decimal value.

3-4	Configuring the Adapter
Setting the Baud Rate		If adapter Configuration DIP Switches SW7 and SW8 (Figure 2.2) are both
		set to ‘On’, the value of Parameter 05 - [RIO Rate Cfg] determines the
		Remote I/O baud rate.
		1. Set the value of Parameter 05 - [RIO Rate Cfg] to the baud rate at which
		your network is operating.
			Port 5 Device				Value	Baud Rate
			20-COMM-R
							0	57.6 Kbps (default)
			Parameter #: 05
							1	115.2 Kbps

2. Reset the adapter (see Resetting the Adapter on page 3-8).

Setting the Starting Module

Group

If adapter Configuration DIP Switches SW7 and SW8 (Figure 2.2) are both set to ‘On’, the value of Parameter 25 - [Start RIO Group] determines the starting module group.

1.Set the value of Parameter 25 - [Start RIO Group] to the desired starting group.

	Port 5 Device			Value		Baud Rate
	20-COMM-R
			0			Group 0 (default)
	Parameter #: 25
