bit5. Synchronous speed match (SYSA)
This signal turns ON during spindle synchronous control, when the mode can be changed from the
speed operation mode to the spindle synchronous operation mode.
bit6. Changing coil (MKC)
When using the coil changeover motor, this signal turns ON for the time set in parameter SP059
(MKT) when the L coil selection command is turned ON or OFF. The coil is not changed when the
orientation command is input, so this signal will not turn ON even if the L coil selection signal is
turned ON or OFF. During orientation control, this signal will turn ON when the orientation
command turns OFF and the coil changeover operation takes place. Do not turn the start signal
ON or OFF while this signal is ON.

bit7. Index positioning completed (WRCF)
This signal turns ON during indexing operation when the spindle position reaches the in-position
range in respect to the target stop position. Once this signal turns ON it will remain ON regardless
of the spindle position until the orientation signal turns OFF or the next indexing operation signal is
input.
This signal will turn OFF for the time set with parameter SP103 (FTM) when the indexing operation
signal is input even if the current stop point and the next indexing position are in the in-position
range.
bit9. Speed detection 2 (SD2)
This signal turns ON when the motor speed drops below the value set with parameter SP058
(SDT2). The ON to OFF hysteresis width is fixed at 15r/min. This signal turns ON when the motor
speed drops below the set speed regardless of the input signal state.

bitD. In automatic adjustment (ATA)
This signal turns ON while the spindle is starting during Z-phase automatic adjustment of the PLG
with MDS-C1-SPM.
bitE. Spindle holding force increased (TLUA)
This signal turns ON while the spindle holding force up (TLUP) signal is input.
