297
Number Contents Remarks
4800 Parameter for synchronization control of
spindle
#0 ND1 : In controlling the spindle synchronization, the
direction of the first spindle motor rotation is the
direction indicated by the command sign (0)/the
opposite direction (1)
#1 ND2 : In controlling the spindle synchronization, the
direction of the second spindle motor rotation is
the direction indicated by the command sign
(0)/the opposite direction (1)
#7 SPK : As the parking signals for simple spindle
synchronous control PKESS1 <G122#6> and
PKESS2 <G122#7> are used (0)/PKESS1
<G031#6> and PKESS2 <G031#7> are used
(1)
4810 Error pulse between two spindles when phase
synchronizing in the serial spindle
synchronization control mode
4811 Allowable error count for the error pulse
between two spindles in the serial spindle
synchronization control mode
4900 Spindle fluctuation detection T series
#0 FLR : The allowable rate and fluctuation rate of
parameter No. 4911 and No. 4912 are
indicated in 1% steps (0)/0.1% steps (1).
T sereis

alarm is activated in the spindle speed
fluctuation detection function
4913 Spindle speed fluctuation value (d) for which no
alarm is activated in the spindle speed
fluctuation detection function
4914 Time (p) elapsed from when the commanded
spindle speed is changed to the start of spindle
speed fluctuation detection
