ABB Frequencyvconverter ACS880 with Powerlink communication.

 This object handles communication with an ABB ACS880 frequency converter over
 Ethernet Powerlink. The object graph and more graph shows the most vital IO signals.

 In addition to the signals used by the ACS880_1, signals that can be user defined
 are present in the Powerlink message. For example digital inputs User1 to User5 are
 normally not used by the converter, and might be used for a local start/stop unit.
 See the Powerlink module object ABB_ACS880_Epl for more information.

 The full value of this object will be achieved if you use object ACS880MotorAggr
 (motor, pump or fan), see class ABB_ACS880MotorAggr.

 Press the "More.." button in the object  graph to open the graph. The status of the
 two most important words are found here, the control word CW (write) and the status
 word SW1.

 For plc coding the function object ABB_ACS880_1Fo is used.
 Create a function object in the plc editor and connect it to the current
 object with the connect function.

 The function object basic task is to read and write to the converter
 statusword SW, control word CW, reference REF and actualvalue ACT.

 For simulation of ACS880_Epl_1, use the plc function object ABB_ACS880_1Sim.

 For Powerlink connection use the powerlink IO Module object ABB_ACS880_Epl_IoModule.
 The object is included as a Io attribute of the Powerlink module object
 ABB_ACS880_Epl, i.e. create an ABB_ACS880_Epl object in the node hierarchy and connect
 the Io attribute to the current object with the connect IO function.

 Some settings is needed in the converter to match the PlcPgm code and
 the object graph, see class ABB_ACS880_Epl for more information.

 Consider the scale settings in the analog channel object of the
 ABB_ACS880_PPO7_IoModule object.

 -Signal RefSpeed   channel O_REF
 -Signal ActSpeed   channel I_ACT
 -Signal ActCurrent channel I_CURR_0107  (32bit)
 -Signal ActTorque  channel I_TORQ_0110

 All the signals between the converter and PLC are displayed in the figure below.

 The ACS880_Epl_1 signal interface to converter has two important words named
 controlword CW and statusword SW. The CW word are not easy to understand.
 For detailed information see ABB manuals.

 The Control word is the principal means for controlling the drive
 from a fieldbus system. The fieldbus master station sends the
 Control word to the drive through the adapter module. The drive
 switches between its states according to the bit-coded instructions
 in the Control word and returns status information to the master in
 the Status word. The contents of the Control word and the Status word
 are detailed below.

 ABB_ACS880_Epl_1 is derived from ABB_ACS800_1 with the following improvements

  -Safe torque off input in the converter i.e. new output [sto] in function object and new signal.
  -All fault and warning messages in text form in object graph.
  -After a stop command it is now possible to start directly without waiting for stop to complete.
  -Graphical interface with more status and a new user status word.
  -Predefined inputs named "User 1" to "User 5" displayed in the object graph.
  -ConvertReady signal added that pays attention to the new STO input (safe torque off)
  -New signal "zero speed" and "magnetized" (good to have in synchronous start etc.)
