Used structures
HMI_MOTOR_A
Auto_Man Bool Command to set the block in Auto or Manu
Run_Stop Bool Command to run or stop the pump
Rst_Fault Bool Command to acknowledge internal and external errors indicated
at the output Error. Acknowledgement is done with a rising edge.
Speed_Setpoint Int Setpoint for motor speed in Manual mode.
Speed_Output Int Output speed from the ATV
Meas_1 Int Object to be congured in the I/O scanner and to be displayed
in the HMI (eg: current, power consumption,…)
Meas_2 Int Object to be congured in the I/O scanner and to be displayed
in the HMI (eg: current, power consumption,…)
Nb_start Int Number of starts performed in the last 24 hours, displayed on HMI
(calculated value)
Min_time_stop Int Miminum time between stop and start
Discrepancy_time Int Maximum time between a command and the right feedback
Time_to_start Dint Time before the next start, calculated when Nb_start reaches the limit,
displayed on HMI.
Sts_Auto Bool Automatic mode is activated. The process sequence manages the motor
Sts_Manual Bool Manual mode is activated. The commands come from HMI or SCADA.
Sts_Local Bool Local mode is activated. The commands are hardwired.
Sts_Off Bool The ATV is powered off by the hardwire.
Sts_Locked Bool Indicates that the operation is blocked by an interlock (input Lock).
Sts_Error Bool Indicates that the operation is blocked by an internal or external
(Input Err) error, which is not acknowledged.
Sts_TimerProtect Bool Number start control is activated (Nb_start_day <>0) and the max starts
number is reached.
Sts_ATV_Ready Bool Starter ready to switch on
Sts_ATV_Run Bool The motor is running (Status from starter)
Sts_ATV_Fwd Bool Motor running in positive direction
Sts_ATV_Bwd Bool Motor running in negative direction
Sts_ATV_Estop Bool ATV emergency stop activated
Sts_ExtErr Bool External error from the process or the system
Sts_NoVoltage_Err Bool No voltage in ATV
Sts_ATV_Err Bool ATV in error
Sts_Discrepancy_Err Bool Discrepancy error. The discrepancy control is activated
( Discrepancy_time<>0 ).
Name String[10] Motor name & location
Functional description
The DFB behaviour is compliant with the previous description (see page 27), except in the following case.
If the operation mode is changed from automatic mode to manual mode, the motor continues at the same
speed. If the operation mode is changed from manual mode to automatic mode, the motor will follow the
commands from the process.
I/O interface associated to ATV61 management needs additional input and output data to control the operating
mode, circuit breaker and contactor state. These I/Os are located in Advantys STB.
