(3) Configure the parameters that are needed for the spindle control in the spindle mode.
The following parameters are the minimum requirements for the spindle-mode rotary axis control.
"#3001 slimt1" (Limit rotation speed (Gear: 00))
"#3005 smax1" (Maximum rotation speed (Gear: 00))
"#3049 spt" (Spindle synchronization acceleration/deceleration time constant)
"#3054 sptc1" (Spindle synchronization multi-step acceleration/deceleration changeover speed 1) to "#3060 sptc7"
(Spindle synchronization multi-step acceleration/deceleration changeover speed 7)
"#3061 spdiv1" (Time constant magnification for changeover speed 1) to "#3067 spdiv7" (Time constant magnification for
changeover speed7)
"#3106 zrn_typ/bitA-9, bit8" (Zero point return specification)
"#3112 cax_spd" (Spindle C axis zero point return speed)
"#3115 sp2_t1" (Time constant in orientation/interpolation mode automatic reference position return (Gear: 00))

13.7.4 Spindle-Mode Rotary Axis Control Command

Spindle-mode rotary axis control can be commanded using the spindle-mode rotary axis control command signal (ROTSPC1:
YB40).
While the spindle-mode rotary axis control command signal is ON, a rotary axis can be controlled as a spindle. (Spindle-mode
rotary axis control mode)
While the spindle-mode rotary axis control command signal is OFF, a rotary axis can be controlled as a servo axis. (Servo
axis control mode)
(*) To change the "Spindle-mode rotary axis command" signal, the "Servo OFF" signal of the rotary axis needs to be turned
ON (*SVFn=1).
While the spindle-mode rotary axis control mode is ON, an S command is enabled for a servo motor. If a positioning or
interpolation command is given during this mode, the operation error (M01 0005) occurs. Before giving a positioning or
interpolation command, you need to turn OFF the spindle-mode rotary axis control command signal to cancel the spindle-
mode rotary axis control mode.
While the servo axis control mode is ON, the axis does not work as a spindle even if you give it an S command. However, the
S command is retained. If you turn ON the spindle-mode rotary axis control command signal, and then turn ON the forward or
reverse run signal, the axis rotates at the retained S speed.
You can monitor the status of the spindle-mode rotary axis control mode using the spindle-mode rotary axis control mode
signal (ROTSPM1: XB40).
