The thick black bar shown on the outside margin of this page will be used throughout this instruction manual to signify new or revised text or figures.

ATTENTION: The drive ma y contain hig h voltages t hat can cause injury or death. Remove all power from the drive, and then verify power has been removed before installing or removing a

PROFIB US module. Failure to observe these preca utions co u ld result i n s e vere bodily injury o r loss of life.

ATTENTION: Only qualified electrical personnel familiar with drive and power products an d the associated machinery sho ul d plan or implement the install at ion, start u p, conf i gu ration, and subsequent mainten ance of the product using a PROF IB US module. Read and und er stand th is manual in its entirety before proceeding. Failure to observe these precautions could result bodily injury and/or damage to equipment.

ATTENTION: DPI host prod uct s mus t no t be dir ec t l y con ne ct ed together via RECBL-xxx cables. Unpredictable behavior due to timing and other internal procedures can result if two or more devices are connect ed in this manner. Failure to observe this precaution could result bodily injury and/or damage to equipment.

ATTENTION: If the PROFIBUS module is transmitting control I/O to the drive, the drive ma y fa ul t when you reset the module. Determine how your drive will respond before re setting an module. Failure to observe this pre caution could result bodily inju ry and/or damage to equipment.

ATTENTION: Comm Flt Action (parameter 9) and Idle Flt Action (parameter 10) let you determ i ne t he action of the module and connected drive if co m m uni cations are disrupted. By def aul t , these parameters fault the dri v e. 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 hazard of injury or equipm ent damage. Failure to observe th i s precaution could result bodily injury and/or damage to equipment.

Step 1. Set the value of parameter 3 (P-DP Addr Cfg) to a unique

node address as shown in figure 4.2.

4.4 Setting the I/O Configuration

The I/O configuration determines the type of data sent to the drive. Logic Command/Status, Reference/Feedback, and Datalinks may be enabled or disabled.

Step 1. Set the bits in module parameter 11 (DPI I/O Config) as

shown in figure 4.3. A “1” enables the I/O. A “0” disables it. Bit 0 is the right-most bit. In figure 4.3, it is highlighted and equals “1.”

(Default) 1 Datalink A 2 Datalink B

3 Datalink C 4 Datalink D 5 - 16 Not Used

Step 2. If Logic Command/Reference is enabled (default),

configure the parameters in the drive to accept the Logic Command and Reference from the module. For example, set Speed Ref A Sel (SP600 drive parameter 90) to “Network” so that the drive uses the Reference from the network. Also, verify that Logic Source Sel (drive parameter 89) is config ured to “Netwo rk” so tha t the d r ive uses the logic command from the network.

Step 3. If you enabled one or more Datalinks (opt ional), confi gure

parameters in the drive to deter mi ne the sou rce and destination of dat a in the Data link(s). Also, e nsure that the PROFIBUS module is the only module using the enabled Datalink(s).

Step 4. Reset the module. Refer to section 4.5.2, Resetting the

Module.

The module is ready to receive I/O from the master (i.e., scanner). You must now configure the scanner to recognize and transmit I/O to the module. Refer to chapter 5, Configuring the PROFIBUS Scanner, for more information.

4.5 Setting a Fault Action

ATTENTION:Parameter 9 (Comm Flt Action) and parameter 10 (Id le Fl t Acti on) let you determine the

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 module parameter 9 (Comm Flt Action) and a different response to an idle scanner using parameter 10 (Idle Flt Action).

Set the values of parameter 9 (Comm Flt Action) and parameter 10 (Idle Flt Action) to the de sired r esp onses as sho wn in ta ble 4. 2. Se e figure 4.4 for sample LCD OIM Fault Action screens.

4.5.1 Setting the Fault Configuration Parameters

If you set module parameter 9 (Comm Flt Action) or module parameter 10 (Idle Flt Action) to “Send Flt Cfg,” the values in the parameters shown in table 4.3 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.
