B-63950EN/02 4.DESCRIPTION OF PARAMETERS
- 357 -
NOTE
The rotation directions and phase shift directions of
the master axis and polygon synchronization axis in
the spindle-spindle polygon turning mode can be
reversed with a programmed command. MNG,
SNG, and HDR are used to reverse an actual
direction relative to the programmed command.
# 3 HSL When phase control is exercised in spindle-spindle polygon turning
mode (parameter COF(No.7602#5) is set to 0), this parameter selects
the spindle that is subject to a phase shift operation for phase
synchronization:
0: The polygon synchronization axis is selected.
1: The master axis is selected.
NOTE
1 Select an axis to which a phase shift command is
applied.
2 Spindle operation for phase synchronization is
performed with both spindles.
# 4 HST When phase control is applied in spindle-spindle polygon turning
mode (parameter COF(No.7602#5) is set to 0), and spindle-spindle
polygon turning mode is specified:
0: Spindle-spindle polygon turning mode is entered with the current
spindle speed maintained.
1: Spindle-spindle polygon turning mode is entered after the spindle
is stopped.
NOTE
This parameter can be used, for example, when
single-rotation signal detection cannot be
guaranteed at an arbitrary feedrate because a
separate detector is installed to detect the spindle
single-rotation signal, as when a built-in spindle is
used. (When bit 7 of parameter No.4016 for the
serial spindle is set to 1, together with this
parameter, a single-rotation signal detection
position in spindle-spindle polygon turning mode is
guaranteed.)
# 5 COF In spindle-spindle polygon turning mode, phase control is:
0: Enabled.
1: Disabled.
