3.1.1.2.- HOMING operation (origin search)
There are three types of origin search, the most complete one is the mode 1:
When the HOME signal turns ON the origin search starts in the direction specified by Pn824 at homing speed marked by
parameter Pn825. When the DEC signal is detected the speed is reduced to the homing approach speed (Pn826) and after
the detection of first C phase pulse the servo will move the homing final move distance (Pn828) at homing creep speed
(Pn827).
To perform this operation a 1 should be written into parameter Pn823, the other values 2 and 3 correspond to next
methods:
2-Use only the DEC signal, the operation will starts at homing approach speed and on the rising edge of DEC
signal the final positioning will be performed.
3-Use only the Z pulse signal, the operation also starts at homing approach speed and at first rising edge of C
phase the final positioning will be performed.
Writing 0 in the parameter Pn823 will disable the HOMING function.
The used parameter for this function goes from Pn824 to Pn828, with the Pn805 and Pn80E used to define the activation
level of DEC and HOME inputs.
3.1.2.- MODE 0
3.1.2.1.- Program table mode.
The NS600 can store up to 128 position tables using the option INDEX in the programming software INDEXWORK.
With the digital inputs SEL4/SEL3/SEL2/SEL1/SEL0 (Selection) is possible to select the first positioning that should be
performed when the START/STOP signal goes on. While the Start signal is ON the several positionings will be performed
following the table. If Start signal goes OFF the action would be interrupted and will restart at the interrupted positioning
when Start signal turns ON again.
When the PGMRES (program reset) turns ON while the START/STOP signal is disconnected, the register were the current
table position is stored will be cleared. So if any interrupt occurs before use the PGMRES input the operation will restart
at table position marked by inputs (SEL4/SEL3/SEL3/SEL1/SEL0) not were the movement was interrupted.
Pay attention that only is possible to select between the first 32 table positions with the digital inputs.
