10. Spindle Functions
Add-
ress Meaning of address
D Synchronous
spindle selection
Select the No. of the
spindle to be
synchronized with
the basic spindle
from the two
spindles.
R Synchronous spindle
phase shift amount
Command the shift
amount from the
Z-phase point (one
rotation signal) of the
synchronous spindle.
A Spindle
synchronization
acceleration/decele-
ration time constant
Command the
acceleration/decele-
ration time constant
for when the spindle
synchronous
command rotation
speed changes.
(Command this to
accelerate or
decelerate at a speed
slower than the time
constant set in the
parameters.)
10.7 Spindle synchronous control I
Command range
(unit)
• A program error (P35) will occur if a
1 to 7 or –1 to –7
value exceeding the command range
1: 1st spindle
or spindle No. without specifications
2: 2nd spindle
is commanded.
• A program error (P33) will occur if
:
7: 7th spindle
there is no command.
• A program error (P33) will occur if the
same spindle as that commanded for
the basic spindle selection is
designated.
• The rotation direction of the
synchronous spindle in respect to the
basic spindle is commanded with the
D sign.
• A program error (P610) will occur if a
spindle not serially connected is
commanded.
• A program error (P35) will occur if a
0 to 359.999 (° )
or value exceeding the command range
0 to 35999 is commanded.
• The commanded shift amount is
–3
(° × 10 )
effective in the clockwise direction of
the basic spindle.
• The commanded shift amount's
minimum resolution is as follows:
For semi-closed
For full closed
• If there is no R command, the phases
will not be aligned.
• A program error (P35) will occur if a
0.001 to 9.999 (s)
or value exceeding the command range
1 to 9999 (ms) is commanded.
• If the commanded value is smaller
than the acceleration/deceleration
time constant set with the parameters,
the value set in the parameters will be
applied.
