Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.ab.com/manuals/gi) describes some important dif...
Motor current greater than the motor's nameplate rating can indicate a high overload or stall condition, such as an overloaded conveyor or jammed gear. These conditions can result in overheating of the motor, and equipment damage. Rapid jam fault detection helps to minimize damage and loss of production. By continuously monitoring the motor current...
Motor current less than a specific level may indicate a mechanical malfunction in the installation, such as a torn conveyor belt, damaged fan blade, broken shaft, or worn tool. Such conditions may not harm the motor, however, rapid detection may help to minimize equipment damage and loss of production. Communication Fault Protection
The preferred way of accessing device parameters is by means of Acyclic (DP-V1) read- and write services. When accessed acyclically, parameters are addressed by their corresponding Index (index equals parameter number). Note that due to technical reasons imposed by the PROFIBUS networking system, it is required to map at least one byte of Cyclic I...
IMPORTANT All changes made to parameter values, saved or not, will take effect immediately even during Data Exchange.
During startup of the network, it is possible to load start-up values (loaded on each transition from offline to online) for all writable parameters by means of the User Prm Data. The PROFIBUS Module will use these settings provided that "Parameter Initialization" (User Prm Data byte #3) is set as "Enabled". Note that this will result in any previo...
The purpose of this chapter is to assist in troubleshooting the E1 Plus PROFIBUS module. ATTENTION Servicing energized industrial control equipment can be hazardous. Electrical shock, burns, or unintentional actuation of controlled industrial equipment may cause death or serious injury. For safety of maintenance personnel, as well as other who may ...
