8 / 56 page Functions STPM01 8/56 Table 5. Internal signal description Symbol Name Description ZCR Zero crossing signal Provides positive pulse every time the line voltage crosses zero AW Active energy Pulse frequency signal proportional to active energy RW Reactive energy Pulse frequency signal proportional to reactive energy SW Apparent energy Pulse frequency signal proportional to apparent energy LIN Line frequency signal This signal is high when the voltage channel value is rising and it is low when the voltage channel is falling. Basically this signal is the sign of dv/dt. BFR Base frequency range This signal is high when the voltage line frequency is outside the nominal band. It is low when the voltage line frequency is inside the nominal band. MA Stepper motor signals Signal available in MOP and MON to drive a stepper motor MB BIT Tamper flag This signal provides the information on the tamper status. If low no tamper is detected, when high a tamper condition has been detected. This signal is part of the status register but is also available on the SDATD pin when in standalone mode. BIL No load condition Provides information on the load condition. This signal is part of the status register but is also available on the SCLNLC pin when in standalone mode. BIL=1 no load condition, BIL=0 normal operation. |
