4 Explanation of Interface Signals
4.3 PLC Output Signals (Bit Type: Y***)
Note
(1) While the above functions are being executed, a change of this signal is disabled for the target spindle. Thus, change
this signal before executing the program command of each function.
If none of the above functions are executed, this signal is enabled immediately upon input.
(2) This signal is disabled for the following functions and conditions.
 At zero point return in the C axis mode of spindle position control (spindle/C axis control)
 In C axis mode of spindle position control (spindle/C axis control)
 Spindle orientation command
 Spindle forward run indexing/Spindle reverse run indexing
 Turret indexing
<Synchronous tapping cycle command>
Turning ON the "Spindle rotation reversal" signal (SPRR: Y18AA) reverses the spindle rotation direction at the
synchronous tapping cycle command. For the "Spindle rotation reversal" signal, the signal corresponding to the tapping
spindle specified in the synchronous tapping cycle command is valid. As listed below, the motor rotation direction of the
tapping spindle differs depending on the combination of the "Spindle rotation reversal" signal and "#3052 spplr" (Spindle
synchronization relative polarity).

Reverse tapping command
(when a synchronous tapping command is given, the sign of the tapping spindle No. (D address) is "-")

Note
(1) Turn ON the "Spindle rotation reversal" signal for the tapping spindle before the synchronous tapping cycle command
is issued. Even though the "Spindle rotation reversal" signal is switched from ON to OFF or from OFF to ON during
the synchronous tapping cycle, the direction of the spindle motor rotation does not change.
