13.7 Spindle-Mode Rotary Axis Control

13.7.6 Operation when Reset is Input During Spindle-Mode Rotary Axis Control

Status of the spindle-mode rotary axis control signal is unchanged after NC reset. However, if you change the ON/OFF of the

spindle-mode rotary axis control command signal at the same time as the reset, the control mode is switched. If you turn OFF

the spindle-mode rotary axis control command signal at the same time as NC reset during the spindle control mode with the

zero point return type selected ("#3106 zrn_typ/bit8" = "0"), the control performs the zero return operation after the reset, and

then activates the servo control mode.

13.7.7 Operation when Emergency Stop is Input During Spindle-Mode Rotary Axis

Status of the "Spindle-mode rotary axis control mode" signal is unchanged when emergency stop is executed or cancelled.

The control retains the spindle-mode rotary axis control mode.

When the command speed changes, multi-step acceleration deceleration is performed as illustrated below.

Multi-step acceleration/deceleration pattern

The spindle specification parameters need to be set as follows for the operation of acceleration/deceleration during the

spindle-mode rotary axis control.

These parameters are also used as multi-step acceleration/deceleration parameters of spindle synchronization control.

"#3001 slimt1 (Limit rotation speed (Gear: 00))" to "#3004 slimt4 (Limit rotation speed (Gear: 11))"

"#3005 smax1 (Maximum rotation speed (Gear: 00))" to "#3008 smax4 (Maximum rotation speed (Gear: 11))"

"#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 speed 7)"
