HY[N] (Index)
Value
Description
0
Absolute setting of position counter: PY=HY[2].
1
Relative setting of position counter:
PY = PY (at event) -HY[2]
5
What to set for PY
during event
2 Do
nothing.
6
Output value
Digital output value if HY[4]=1.
Only outputs defined as general output are affected.
7
PY captured
value
Captured value of PY, before any modification by the
HY[N] command (read only).
8
PX captured
value
Captured value of PX (read only).

Notes:
HY[2] - HY[6] can be changed during the home search procedure. The activation
of the parameters is considered upon reception of the next HY[1]=1 (or higher).
If HY[2] is set to a value beyond YM[1] and YM[2], the actual auxiliary position
will not be updated when homing is complete.
Each homing event is attached to a predefined functionality (FLS, General
Purpose, Home and so on). If the corresponding input is not defined first, the
homing procedure may never end. Refer to the
IL[N]
command.
The homing and capture procedures can be carried out in any unit mode (UM=1,
2, 3, 4, 5) and reference mode (RM=0, 1).
In external reference mode (RM=1), when HY[4]=0, the software portion of the
reference is stopped, while the external portion is not. In such cases, the motor
continues to move according to the analog reference.
Homing can be safely carried out in the PTP and jog position motion modes. With
PT and PVT modes, the online reloading of the position counter can lead to an
immediate, automatic MO=0 due to excessive position error.
When the Index or Home signal captures PY, the PX captured value is taken at the
next position controller sampling time (4 TS period). It may differ from the PX
value at the capture time by up to 4*TS*10
-6
*VY counts.
When the Index or Home signal captures PY, the digital output of HY[6] is set
only at the next position controller sampling time (4 TS period).
