Output Description

Function Block PUMP_DRIVE_SIMU

DONE (done)

Data type: BOOL

Output DONE indicates the processing state of the block. After completion or abortion of processing (due to an error), DONE is set to TRUE for one cycle. This output always has to be considered together with output ERR. If ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.

ERR (error)

Data type: BOOL

Output ERR indicates whether an error occurred during data reception. If ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.

ERNO (error number)

Data type: WORD, default value: 0, range: ³ 0

Output ERNO provides an error identifier if an invalid value was applied to an input. ERNO always has to be considered together with the output ERR. The value output at ERNO is only valid if ERR is TRUE. The error messages encoding at output ERNO are explained at the table below.

READY (ready)

Data type: BOOL

TRUE indicates that the drive is ready to start and there is no fault.

(input “EX_FAULT” is FALSE)

OPERATING (operating)

Data type: BOOL

TRUE indicates that the drive is operating.

TRIPPED (tripped)

Data type: BOOL

TRUE indicates the pump is tripped (input “EX_FAULT” is TRUE).

ACT_SPEED (actual speed)

Data type: REAL , unit: RPM

Actual speed of the drive.

DRIVE_ACT_PWR (drive actual power)

Data type: REAL, unit: kW

Drive calculated power. It is based on the DRIVE_MAX_SPEED and DRIVE_MAX_PWR inputs.
