Option Name Description
[0] Not Needed If selected, homing operation does not
need to be carried out.
[1] In Specified Direction If selected, homing operation has to be
carried out before positioning. In this
mode, the homing direction should be
specified by the sign of parameter 33-03
Homing Velocity. It means that the user
must know that the home position is at
forward or backward direction relative to
the current position before homing.
[2] Auto-Reverse Between HW Limits If selected, homing operation also has
to be carried out before positioning. In
this mode, homing operation should
work together with HW limit switches,
otherwise the homing behavior is the
same as selection [1] Forced manual
homing. In this mode, the homing motion
starts with the velocity set in parameter
33-03 Homing Velocity, once any 1 of
HW limit switches is probed, the homing
direction is reversed until the home
switch is probed. If the home switch was
still not probed after both HW Neg. and
Pos. limit switches were probed, the alarm
Position Ctrl. Fault is reported with fault
reason Cannot find home position, which is
shown in parameter 37-18 Pos. Ctrl Fault
Reason.
[3] Once with store If selected, homing operation does not
need to be carried out. In this mode, the
position is set to 0 when enabling the
homing. When enabling the homing for
the first time, the homing flag is set to 1
and stored. (This means after the 1st time
enabled, the homing flag will always be
set to 1.)
33-01 Home Offset
Default value: 0 Parameter type: Range (-1073741824–
1073741824)
Setup: 1 setup Conversion index: 0
Data type: Int32 Change during operation: True
Use this parameter to set an offset of 0 (home position) compared to the position after homing.
