l
EDSVS9332S−EXT EN 2.0
Direct homing
The home position is on the home position offset.
l Mode 20 (C0932 = 20):
– Directly after the activation (REF−ON = HIGH), the drive traverses from the actual position
(REF−ACTPOS) to the home position.
– Before that, the actual position (REF−ACTPOS) can be loaded with the input value
REF−ACTPOS−IN (see chapter 3.2.56.3).
– The route and direction of travel results from the actual position (REF−ACTPOS) and the
home position offset (C0934) set.

l Mode 21 (C0932 = 21) is the same as mode 20 but additionally features:
– The actual position value (REF−ACTPOS) is stored when the mains is disconnected and
reloaded when the mains is connected.
3.2.56.3 Control via input signals
l REF−ON = LOW−HIGH edge starts homing:
– The input must remain on HIGH until the end of the homing process. Homing is aborted if
the input is set to LOW before the home position is reached.
l REF−ON = LOW interrupts homing:
– The drive is decelerated to zero speed along the ramp set under C0936.
– The inputs REF−N−IN and REF−PHI−IN are switched to the outputs REF−N−SET and
REF−PSET.
– Has no effect if homing is already completed (REF−BUSY = LOW).
l REF−POS−LOAD = LOW−HIGH edge
– The profile generator accepts the angle at the input REF−ACTPOS−IN as starting value in the
actual position value REF−ACTPOS.
– The function is only active if REF−ON = LOW
– The function is only active in the modes 20 and 21.
