l
EDSVS9332S−EXT EN 2.0
3.2.56.4 Output of status signals
l REF−BUSY = HIGH: the homing function is active:
– The profile generator is switched to the outputs REF−PSET and REF−N−SET.
l REF−BUSY = LOW: the homing function is not active nor is it completed:
– The inputs REF−N−IN and REF−PHI−IN are switched to the outputs REF−N−SET and
REF−PSET.
l REF−OK = HIGH: homing has been completed successfully:
– Homing is completed when the setpoint of the profile generator has reached the home
position.
– If a following error is present, it is transferred into the function block DFSET and corrected
(see chapter 3.2.56.5), provided that the drive is not operated within the torque limitation.
l REF−OK = LOW:
– Homing is currently being executed or
– the home position is no longer known, e.g. due to a failure, or
– homing has been interrupted.
3.2.56.5 Function block interconnection
l REF−PSET provides the angle setpoint belonging to REF−N−SET (following error) for the angle
controller in the function block MCTRL.
– Faultless homing requires a processing of both signals (REF−PSET and REF−N−SET).
l The homing function must be connected to the function block DFSET (see signal flow diagram
for the configurations 5000, 6000 and 7000).
– Otherwise accumulating angle errors may occur.
