4. DESCRIPTION OF PARAMETERS
393
7631
Allowable spindle speed deviation level in spindle–spindle polygon turning
[Data type] Byte
[Unit of data] min
–1
[Valid data range] 0 to 255
[Standard setting value] 1 to 10
This parameter sets the allowable level of deviation between the actual
speed and specified speed of each spindle in spindle–spindle polygon
turning. The value set with this parameter is used for both the master axis
and polygon synchronization axis.
7632
Steady state confirmation time duration in spindle polygon turning
[Data type] Word
[Unit of data] ms
[Valid data range] 0 to 32767
This parameter sets the duration required to confirm that both spindles
have reached their specified speeds in spindle–spindle polygon turning.
If the state where the speed of each spindle is within the range set with
parameter No.7631, and has lasted at least for the duration specified with
parameter No.7632, the spindle polygon speed arrival signal PSAR (bit
2 of F0063) is set to 1.
7635
Multiplier influencing the slave spindle speed
[Data type] Byte
[Unit of data] Slave spindle (min
–1
)/master spindle (min
–1
)
[Valid data range] 1 to 9
Set up a multiplier that will act on the distance through which the slave
spindle is to move.
In speed ratio control, the relationship between the speeds of the spindles
is:
(Slave spindle speed) = (master spindle speed) × (setting of parameter No.
7635)
NOTE
The spindle synchronization option is needed.
It is valid when parameter SBR (bit 2 of parameter No. 7603)
= 1.
