Motor with a Frequencyconverter using Profibus PPO3 protocol

 The BaseFcPPO3MotorAggr object handles a motor controlled by a frequency
 converter via the fielbus Profibus, using the protocol PPO3. The aggregate
 also includes contactor, circuitbreaker and safetyswitch.

 The object handles several modes and configurations. The controlled
 unit can be handled locally or remotely.

 - Local mode    The unit is controlled from a local panel close to the drive.

 - Remote mode   The unit is controlled from the control system, either by
                 the operator from the object graph, or by PLC program.

 The local mode has higher priority than the remote.

 The mode handling also contains an extern and intern mode.

 - Intern mode   The unit is handled by the built-in Auto/Man function,
                 basically from the Auto/Man buttons in the object graph.

 - Extern mode   The built-in Auto/Man function is not used. Auto/Man is
                 handled from the plc program and other graphs.

 Which of these modes that are present depends on the configuration.

 Modes that can be configured

 - Intern          Auto/Manual mode is controlled from buttons in the
                   object graph. This is the default configuration.
 - Extern          Auto/Manual mode is controlled from the PLC program.
                   The Auto/Man buttons are removed from the object graph
                   but the Start/Stop buttons are still present.
                   Set attribute OpIntOnly to 1.
 - Extern only     Auto/Manual mode is controlled from the PLC program.
                   No Auto/Man or Start/Stop  buttons are present in the
                   object graph. Set attribute OpExtOnly to 1.
 - Intern only     Only manual mode is present, and the Auto/Man buttons
                   are removed. Set OpIntOnly to 1.
 - Local           When the local panel is activated, and the Start/Stop
                   buttons of the local panel is used. To disable this
                   mode, set OpNoLocal to 1.

 The graphical symbol for this object is BaseComponent/BaseFcPPO3MotorAggr.

 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.

 Default action:
 - the methods menu is opened with MB3.

 Indicators:
 - the Ready indicator is green when the motor is started.
 - the Interlock indicator is red when the motor is interlocked, and
   the object symbol is colored yellow.
 - the Start indicator is green when the drive is active.
 - the Local mode indicator is yellow when local mode is active, and the
   Start/Stop buttons are dimmed.
 - the Extern indicator is visible when the Auto/Man selection isn't
   made from the object graph, but from the plc function object.
 - the Contactor indicator is green when the contactor is energized.
 - the frequency converter indicator is green when the converter is ready,
   otherwise it's yellow.
 - the SafetySwitch indicator is green when the safetyswitch is on, and
   yellow when off.
 - other indicators are normally green and colored red at fault condition.

 The field Starts shows the number of times the motor is started, and Run
 the run time of the motor.

 From the Auto/Man pushbuttons the mode is switched, and the Start/Stop
 buttons are used to control the motor in manual mode.

 - the Start button has toggle function.
 - in Auto mode, the Incr/Decr and Stop buttons are dimmed.

 The figure shows a configuration where the Auto/Man mode is controlled by
 the ExtControl input of the function object. Auto mode is set when the
 input i high and the contactor order output is controlled by the input
 ExtStart. To get this configuration, use CbCoFcSl and set Mode.OpExtAndIntMan
 to 1.

 The contactor and motor objects has also configuration alternatives.
 The motor can be configured with overtemperature switch or sensor, and
 the contactor with or without feedback, and with pulsed order signals.

 Signals that should be connected to channel objects:

 - CircuitBreaker.NotTripped     Di (optional)
 - Contactor.Order               Do (optional)
 - Contactor.OrderOff            Do (optional)
 - Contactor.Feedback            Di (optional)
 - SafetySwitch.On               Di (optional)
 - Motor.TempSwitch.Switch        Di (optional)
 - Motor.TempSensor.Value        Ai (optional)

 The mode functions are found in the CompModeA object. See this object
 for more info.

 If the mode object is configured for extern control only, the Error output
 of the function object should be used to reset the start input to avoid
 unwanted restarts.

 For plc coding the function object BaseFcPPO3MotorAggrFo is used.

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

 For profibus connection with protocol PPO3 use the profibus Module object
 BaseFcPPO3PbModule.
 Create a module object in the node hierarchy by selecting BaseFcPPO3PbModule
 as Module Class in the profibus configurator, and connect the Io attribute
 of the BaseFcPPO3PbModule object to the FrequencyConverter object with the
 connect function. The FrequencyConverter object is an attribute in the
 BaseFcPPO3MotorAggr object.

 To display the current and torque in the object graph, PZD3 and PZD4 has to be
 configured in the frequency converter to show current and torque.

 -PZD3  configure for current in the frequency converter.
 -PZD4  configure for torque in the frequency converter.

 The conversion of the reference value, process value, current and torque has to
 be configured in the channel objects.

 -O_REF     Reference
 -I_ACT     Process value
 -I_PZD3    Current
 -I_PZD4    Torque

 For simulation of the motor, use the plc object BaseFcPPO3MotorAggrSim.

• BaseFcPPO3MotorAggrFo
• BaseFcPPO3MotorAggrSim
• CompModeA
• BaseFcPPO3
• BaseFcPPO3PbModule
