MLPhaReadActPhase

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Gets the actual phase value of a phaser block.

Inputs

Input	Data Type	Range	Unit	Default	Description
Enable Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set. Both are required for enabling the drive.

Remarks

• 
  

• This function or function block returns cached data.
  See Program a Multi-Core Controller.

• If a PHASE_SLOPE_USER value is used, the new phase isn’t set immediately.
  • See MLPhaWritePhase.
  • The phase is ramped The gradual acceleration and deceleration of a stepping motor. This is essential if performance beyond the start/stop range is required. The slope of the ramp is a function of screw pitch, load, drive voltage and design, and motor. with the slope value from the old phase value to the new phase value.
  • MLPhaReadActPhase returns this ramping value.
  • See MLPhaReadSlope and MLPhaWriteSlope.
• MLPhaReadPhase returns the new value and this also when the phaser is still ramping.
  • If using Max Slope means no ramping.
  • MLPhaReadActPhase and MLPhaReadPhase always returns the same value.
