l
EDSVS9332K−EXT EN 4.0
Direct homing
The home position is on the home position offset.
l Mode 20 (C0932 = 20):
– The drive moves from the actual position (REF−ACTPOS) to the home position immediately
after the activation (REFC−ON = HIGH).
– The actual position (REFC−ACTPOS) can previously be loaded with the input value
REFC−ACTPOS−IN.
– The travel path and the direction of travel result from the actual position (REFC−ACTPOS)
and the set home position offset (C0934).

l Mode 21 (C0932 = 21) as mode 20, but in addition:
– The actual position (REFC−ACTPOS) is saved during mains disconnection and is loaded
again at mains connection.
3.2.83.3 Control via input signals
l REFC−ON = LOW−HIGH edge starts homing
– The input must remain on HIGH until the end of the homing mode. Homing is aborted when
the input is set to LOW before reaching the home position.
l REFC−ON = LOW interrupts homing
– The drive is decelerated to zero speed along the ramp set under C0936.
– The inputs REFC−N−IN and REFC−PHI−IN are set for the outputs REFC−N−SET and
REFC−PSET.
– Has no effect if homing has already been completed (REFC−BUSY = LOW).
l REFC−POS−LOAD = LOW−HIGH edge
– The profile generator accepts the phase applied at input REFC−ACTPOS−IN as starting value
for the actual position REFC−ACTPOS.
– The function is only effective if REFC−ON = LOW.
– The function is only effective in modes 20 and 21.
