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
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 <F044#3> 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.
4811
Allowable error count for the error pulses between two spindles in the serial
spindle synchronization 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.
NOTE
This parameter is used to output the inter–spindle phase
error detection signal SYCAL in the serial spindle
synchronization control mode. The SYCAL <F044#4>
signal becomes “1” when a phase error exceeding the value
set in this parameter is found.
