13.7.13 Precautions

(1) When using the spindle-mode rotary axis control, disable the collision detection function.
The parameter "#2260 SV060 TLMT" (Collision detection level) needs to be set to "0" to disable the collision detection.
(2) The available spindle speed at the spindle end is up to the maximum (a value obtained by dividing "#2001 rapid" by
"#2218 PIT") of the parameter "#3001 slimt1" (Limit rotation speed). Set the spindle parameters "#3001 slimit1" to "#3004
slimit4" (Limit rotation speed) and "#3005 smax1" to "#3008 smax4" (Maximum rotation speed), so that the motor side
speed does not exceed the servo motor's maximum rotation speed.
(3) Even when the servo OFF signal is ON (*SVFn=1) for the rotary axis, the axis remains servo OFF while the spindle for-
ward and reverse run signals are OFF with the spindle-mode rotary axis control signal ON.
If you set the axis to be in servo ON (energized) state with the spindle-mode rotary axis control signal ON, turn ON the
spindle forward or reverse run signal.
(4) While the spindle-mode rotary axis control command signal is ON and the servo OFF signal is OFF (*SVFn=0), the axis
will not rotate even when the forward or reverse run command is given.
Give the forward or reverse run command with servo ON (*SVFn=1).
(5) While the spindle-mode rotary axis control command signal is OFF, the spindle forward and reverse run signals are dis-
abled. If you turn ON the spindle-mode rotary axis control command signal with the forward or reverse run signal ON, you
need to re-input (turn OFF and ON) the forward or reverse run signal.
(6) When switching the control mode between spindle-mode rotary axis control and servo axis control, you need to have the
zero point established. Establish the zero point of the rotary axis before switching the control mode.
If you turn ON the spindle-mode rotary axis control command with the zero point unestablished, and then give a spindle
command, the axis does not function as a spindle.
(7) Change the "Spindle-mode rotary axis control command" signal (ROTSPCn: YB40) in servo ON (*SVFn=1) state.
When the "Spindle-mode rotary axis control command" signal is changed in servo OFF (*SVFn=0) state, the mode can be
switched from the servo axis mode to the spindle mode, but not from the spindle mode to the servo axis mode.
