13.6.7 Relation with Other Functions

 Spindle orientation

This function does not support mag-sensor (proximity switch) orientation.

 Spindle position control (spindle/C axis control)

Under spindle-mode servo control, the spindle/C axis parameter switch cannot be performed in parallel with the change-

over between spindle and C axis control.

Thus set "0" (Not switch) in the parameter "#3114 cax_para_chg" (Spindle/C axis parameter switch). If this parameter is set

to "1" (Switch), the operation error (M01 1026) occurs when a C axis changeover command is given.

 Coil switch/automatic coil switch

Coil switch is not available for this function, as this control is for a servo motor.

 High-speed synchronous tapping

High-speed synchronous tapping is not available for this function. If this command is given to a spindle-mode servo, the

command is treated as a normal synch tap command.

 Guide bushing spindle synchronization

Spindle-mode servo cannot be set as "reference spindle for G/B" or "G/B spindle".

Thus set "0" in the parameter "#3074 GBsp" (Guide bushing spindle synchronization control).

If either reference spindle for G/B ("#3074 GBsp (Guide bushing spindle synchronization control)" is set to "1") or G/B spin-

dle ("#3074 GBsp (Guide bushing spindle synchronization control)" is set to "2") is assigned to a spindle-mode servo, the

operation error (M01 G1015) occurs at the turning-ON of "G/B spindle synchronization valid" signal (GBON: Y778).

 Increase holding power of spindle

Turning-ON or turning-OFF of "Increase holding power of spindle" signal (EXOBS: Y1893) cannot switch the enable or dis-

able state of disturbance observer.

 Load Monitoring I

Spindle-mode servo does not output the spindle cutting torque, estimated spindle disturbance torque or effective spindle

torque to the R registers.

 Disable collision detection for a spindle-mode servo.

Set "0" in the parameter "#2260 SV060 TLMT" (Collision detection level).
