5. Spindle Adjustment
5 - 24
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.

bit8. In 1-drive unit 2-motor changeover (MTC)
This signal turns ON during motor changeover with 1-drive unit 2-motor specification.
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.
