ND2 ND1
NOTE
When this parameter is set, the power must be
turned off before operation is continued.
[Data type] Bit
ND1 In controlling the spindle synchronization, the direction of the first
spindle motor rotation is:
0 : The direction indicated by the command sign
1 : The opposite direction to that indicated by the command sign
ND2 In controlling the spindle synchronization, the direction of the 2nd
spindle motor rotation is:
0 : The direction indicated by the command sign
1 : The opposite direction to that indicated by the command sign
SYM As the maximum spindle speed in spindle synchronization control:
0 : The maximum spindle speed of the master spindle is used.
1 : The maximum spindle speed of the master spindle or slave
spindle, whichever lower, is used.
4810
Error pulse between two spindles when synchronizing phases in the serial
spindle synchronization control mode
[Data type] Byte
[Unit of data] Pulse
[Valid data range] 0 to 255
Set the difference in error pulses between two spindles when
synchronizing phases in the serial spindle synchronization control
mode.
When the difference in error pulse between two spindles is within the
value set in this parameter, the spindle phase synchronization
completion signal FSPPH becomes "1".
This parameter is used to check the difference in phase in
synchronization control and to confirm the completion of
synchronization in the serial spindle synchronization control mode.
For spindle synchronization, serial spindle parameters such as
parameter No. 4032 must be set.
4811
Allowable error count for the error pulses between two spindles in the serial
spindle synchronization control mode or simple synchronous control mode
[Data type] Word
[Unit of data] Pulse
[Valid data range] 0 to 32767
Set the allowable error count for the error pulses between two spindles
in the serial spindle synchronization control mode or simple
synchronous control mode.
