Safety Precautions

Please read the following safety precautions carefully

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

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 a PROFIBUS adapter.

ATTENTION: Risk of equipment damage exists. The PROFIBUS 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 PROFIBUS 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 9 - [Comm Flt Action] and 10 - [Idle Flt Action] let you

determine the action of the adapter and connected PowerFlex drive if communications are disrupted. By default, these parameters fault the PowerFlex drive. You can set these parameters so that the PowerFlex drive continues to run. Precautions should be taken to ensure that the settings of these parameters do not create a hazard of injury or equipment damage.

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.

By default, when communications are disrupted (for example, a cable is disconnected) or the master is idle, the drive responds by faulting if it is using I/O from the network. You can configure a different response to communication disruptions using Parameter 9 - [Comm Flt Action] and a different response to an idle scanner using Parameter 10 - [Idle

Flt Action].

ATTENTION: Risk of injury or equipment damage exists. Parameters 9 - [Comm Flt Action] and 10 - [Idle Flt Action] let you

determine the action of the adapter and connected drive if communications are disrupted or the scanner is idle. 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.

To change the fault action

• Set the values of Parameters 9 - [Comm Flt Action] and 10 - [Idle Flt Action] to the desired responses:

Value Action Description

0 Fault (default) The drive is faulted and stopped. (Default) 1 Stop The drive is stopped, but not faulted. 2 Zero Data The drive is sent 0 for output data after a

To set the fault configuration parameters

If you set Parameter 9 - [Comm Flt Action], or 10 - [Idle Flt Action] to the “Send Flt Cfg,” the values in the following parameters are sent to the drive after a communications fault and/or idle fault occurs. You must set these parameters to values required by your application.

Number Name Description

13 Flt Cfg Logic A 16-bit value sent to the drive for Logic Command. 14 Flt Cfg Ref A 32-bit value (0 – 4294967295) sent to the drive as a 15 – 22 Flt Cfg x1 In or

Resetting the Adapter

Changes to switch settings or some adapter parameters require that you reset the adapter before the new settings take effect. You can reset the adapter by cycling power to the drive or by using the following parameter:

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 a connected adapter.

• Set the Parameter 08 - [Reset Module] to Reset Module:
