Motor with ABB Frequencyconverter ACS880

 The ABB_ACS880MotorAggr object handles a motor controlled by a ABB frequency converter ACS880 through
 fieldbus Profibus/DP communication with standard PPO7 protocol. One main contactor (power) could
 also be controlled by this object. Simple writing/reading of parameters can be done in a special
 graph named "more".

 See also pump class ABB_ACS880PumpAggr and fan class ABB_ACS880FanAggr.

 The aggregate can be configured with many different components, with different modes Auto/Man/Local
 and with a lot of options.

 Components except the motor and converter:

  - Circuitbreaker       MCCB.
  - Contactor            Pulse maneuver is possible with two digital outputs on/off.
  - Safetyswitch         In the main circuit or maneuver circuit (startlock).
  - Fuse

 The graphical symbol for this object is ABB/ABB_ACS800MotorAggr,
 note that the symbol is the same as old converter type ACS800.

 Default dynamics:

 - the motor is filled with the original color when the motor is on.
 - colored gray when the motor is off.
 - colored red when an error occurs.
 - colored yellow when a warning occurs.
 - indicating the current mode:

   M:  Manual mode.
   L: Local mode, mode is set to auto when local is left.
   LM: Local mode, mode is set to manual when local is left.
   No indication: auto mode.

 Each of these options has an object graph that automatically appears when you open the object
 graph in runtime. The choice will also create or hide the components in the object.

 After the configuration you have to configure and connect the IO signals for chosen components,
 see below.

 The components of the object contain signals that must be connected to IO channels or disabled.
 For components that have several IO options, the "ConfigureComponent" method is used. For
 components that only contains one single IO signal, the "Disable" method i.e:

  - CircuitBreaker.NotTripped     Di (configuration via Disable method)
  - SafetySwitch.On               Di (configuration via Disable method)

  - Contactor.Order               Do (configuration via "ConfigureComponent" method)
  - Contactor.OrderOff            Do (configuration via "ConfigureComponent" method choose TwoOrderFeedback)
  - Contactor.Feedback            Di (configuration via "ConfigureComponent" method)
  - Motor.TempSwich.Switch        Di (configuration via "ConfigureComponent" method)
  - Motor.TempSensor.Value        Ai (configuration via "ConfigureComponent" method)

 Different modes, Auto/Manual/Local, are handled by the CompModeA object.

 Note that local mode refers to control from a local cabinet placed close to the motor,
 NOT the inverters local mode in display panel on the inverter.

 Mode function:

  -Error handling for manual operation (5 alarm).
  -Dimmed pushbuttons in the object graph to avoid incorrect operation.

 Modes that can be configured: (extern control = outside the object)

 1 Remote mode auto/man  Auto/manual mode is controlled by pushbutton in the graph.
 2 Remote mode extern    Auto/manual mode is controlled by "extern" function via PLC program.
 3 Remote mode extern    The motor is controlled as 2, but pushbutton Start/Stop can be used in the graph.
 4 Internal mod          The motor is controlled only by pushbutton Start/Stop used in the graph.
 5 Local mod             The motor is controlled from a cabinet/box placed close to the motor.

 Mode description related to 1-5 over: (attributes in the CompModeA object)

 1 This is the default configuration.
 2 No pushbutton in graph by setting attribute OpExtOnly to 1.
 3 As number 2 but Start/Stop button are present in graph. Set attribute OpExtAndIntMan to 1.
 4 Setting attribute OpIntOnly to 1.
 5 Handled by function object input Local. Disable local by setting attribute OpNoLocal to 1.

 NoteOnly one of the three mode attributes in CompModeA: OpExtAndIntMan, OpIntOnly, OpExtOnly,
 should have value 1, or the object will not work properly.

 NoteIf configuration is external control (Auto/Man pushbuttons are disabled) it is recommended
 to use the Error {err] output of the function object to reset external order and avoid
 unwanted starts. It is also important to handle the local input OpLocStart [lst]
 in the same way. See example below.

 NoteIf the attribute OpNoAutoToMan in object CompModeA is set to 1, it is important to,
 in the PLC code, reset the input ExtStart [est] or reset the input ExtControl [eco] if this
 has been used. The reason is to avoid unwanted starts.

 NoteIf local mode is used, it is important to reset start order input LocalStart [lst] to
 avoid unwanted start, see example below.

 The picture shows an example when output [err] from a function object is used to reset local
 start input [lst]. The reset code is yellow in the picture. Note that the code example is from
 a BaseMotorAggr object, but in principle it is the same for an ABB_ACS800MotorAggr.

 See also object CompModeA for more information.

 For plc coding the function object ABB_ACS880MotorAggrFo is used.

 Create a function object in the plc editor and connect it to the current
 object in plant hierarchy with the connect function.

 Startorder (via control word MainControlCW) and analog reference output (RefSpeed) via
 Profibus to the inverter are controlled by four different modes:

  1 Input ExtStart [est] from function object and intern auto/man mode.
  2 Input ExtStart [est] from function object and extern auto/man mode [eco].
  3 Start/stop buttons in the graph in manual mode.
  4 Input LocalStart [lst] from function object if input LocalMode [loc] is active.

 The analog reference is taken from input RefSpeedExt [REX] in auto/extern mode and
 input RefSpeedLoc [RLO] in local mode, or internal via graph (OpRefMan) in manual mode.

 Note if a contactor with start and stop pulse is used and input pin 'pil' Power Interlock
 goes low/false a stop pulse is generated.

 For profibus connection with protocol PPO7 use the profibus Module object
 ABB_ACS880_PPO7. The object is created by the profibus configurator
 under a ABB_ACS880_Pb_Slave object in the node hierarchy.
 The class ABB_ACS880_PPO7 will automatic be generated together with
 ABB_ACS880_PPO7_IoModule. See class ABB_ACS880_Pb_Slave for more information.

 Connect the Io attribute of the ABB_ACS880_PPO7_IoModule object to the ACS880 object
 with the connect function. The ACS880 object of class ABB_ACS880_1 is an attribute in
 the ABB_ACS880MotorAggr object.

 See class ABB_ACS880_1 for more information about IO connect, two figures describe
 the IO connect methode in detail. Note If the menu option 'IO connect' is dimmed use
 normal channel IO connect methode i.e. 'ctrl + mouse dubbel click left button' on the
 plant hierarchi attribute 'IoConnect' when the node hierachi attribute 'Io' is selected.

 To adapt the frequency converter to this configuration, some settings
 have to be performed, see class ABB_ACS880_PPO7.

 Signal scale settings in the object ABB_ACS880_PPO7_IoModule channel ChanAi
 and ChanAo to consider is:

 -Signal RefSpeed   channel O_REF
 -Signal ActSpeed   channel I_ACT
 -Signal ActCurrent channel I_PZD3_PZD4  (32bit)
 -Signal ActTorque  channel I_PZD5

 See class ABB_ACS880_1 for more information.

 For simulation of the motor, use the plc function object ABB_ACS880MotorAggrSim.

 The previous variant ACS800 is almost the same as ACS880 but some improvements are added
 in this aggregate frequency object ACS880 i.e:

  -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.
  -Alarm message converter fault (inhibit) removed.
  -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 input 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.)

 Up to 24 different graph object for this aggregate.
 The choice is automatic when the configureComponent method
 in pop up menu is executed. Note do not change this choice
 manually because it should match the components.

 The aggregate is ready for remote start and no external interlocks exist.
 Use this attribute when false to reset start commands to avoid unwanted
 restart of the motor or use output pin "err" from function object in the
 PlcPgm.

 The aggregate is ready for remote start and no internal interlocks exist
 as safetey switch, curcuit braker etc.

 External interlocks, example, low level, high temp etc.

 Local mode i.e. status from input pin "loc" in function object in the PlcPgm.

 If this attribute is true the start/stop commands is given from a local panel
 close to the motor i.e. from input pin "lst" in function object in the PlcPgm.

 The local mode has the highest priority i.e. all other start commands except
 from input pin "lst" is ignored.

 Button power/contactor "on" in the object graph. The attribute will
 be reset after commands has detected.

 Button power/contactor "off" in the object graph. The attribute will
 be reset after commands has detected.

 Power interlock i.e. status from input pin "pil" in function object in the PlcPgm.
 Normal use is for E-stop and other interlocks if power on is not allowed.

 If no contactor is used the interlock still works, i.e. no start is allowed.

 Dimmed button power/contactor "on/off" in the object graph i.e.
 if power interlock is true is not allowed to switch on the power.

 The object has a warning, the object symbol will be yellow.

 The object has a fault, the object symbol will be red.

 Count starts and measure the time the motor is on etc.

 Alarm message power on (contactor) command is given to often.
 (This protect the converter hardware)

 Alarm message if power on (contactor) command is given and
 object is power interlocked.

 Alarm message if start command is given and object is not ready.

   Circuit breaker MCCB i.e. to protect the converter and cable from
   shortcut and over current,

   Contactor used for energized the converter.

   ACS880 driver/frequency converter for motor speed
   control.

   Safety switch for easy and safe maintenance i.e. this switch
   always located close to motor and lockable.

   Motor. Contain temperature supervision (switch or sensor)
   and motor data.

   Mode control i.e. local/remote, auto/man, start/stop and
   speed reference. Button name start/stop or on/off are
   configurable.

  Trend pointed to ACS880 plot group speed, current
  etc.

 Supervision disabled i.e. status from input pin "dis" in function
 object in the PlcPgm. If true this will disable alarm message from
 components contactor, safety switch etc. except the ACS880 object.
