l
Mode 21 (C0932 = 21) like mode 20 plus the following:
– The actual position value (REFC-ACTPOS)is stored when the drive is disconnected from the
mains and loaded when the mains is switched on again.
7.6.64.3 Control via input signals
l
REFC-ON = LOW-HIGH transition starts homing:
– The input must remain on HIGH until the end of homing. Homing is interrupted if the input is
set to LOW before the home position has been reached.
l
REFC-ON = LOW interrupts homing:
– The drive is decelerated to 0 according to the ramp selected.
– The inputs REFC-N-IN and REFC-PHI-IN are connected to the outputs REFC-N-SET and
REFC-PSET.
– No effect if homing is already over (REFC-BUSY = LOW).
l
REFC-POS-LOAD = LOW-HIGH transition
– The profile generator accepts the phase applied to the input REFC-ACTPOS-IN as start
value in actual position value REFC-ACTPOS.
– The function is only effective if REFC-ON = LOW.
– The function is only effective when using the modes 20 and 21.
7.6.64.4 Output of status signals
l
REFC-BUSY = HIGH: homing function is active:
– The profile generator is connected to the outputs REFC-PSET and REFC-N-SET.
l
REFC-BUSY = LOW: homing function is not active or completed:
– The inputs REFC-PHI-IN and REFC-N-IN are connected to the outputs REFC-PSET and
REFC-N-SET.
l
REFC-OK = HIGH: homing has been completed successfully:
– Homing is completed if the setpoint of the profile generator has reached the home position.
l
REFC-OK = LOW:
– Homing is being carried out or
– the home position is, for instance, because of a fault unknown or
– homing has been interrupted.
