4.3 Setting the Initial Parameters for the Spindle Drive Unit
(2) Time constant settings during acceleration/deceleration
Set the time constant from the stopped state to reach S commands of smax.
#3101 sp_t 1 Acceleration/deceleration time constant with S command (Gear: 00)
Set the acceleration/deceleration time constant with S command (speed operation mode) when gear
00 is selected. Set the linear acceleration/deceleration time up to limit rotation speed (slimit1). Set
the short time constant that the motor torque at acceleration is always saturated, however, when an
abnormal noise or V-belt slip occurs, increase the time constant.
---Setting range---
0 to 30000 (ms)
#3102 sp_t 2 Acceleration/deceleration time constant with S command (Gear: 01)
#3103 sp_t 3 Acceleration/deceleration time constant with S command (Gear: 10)
#3104 sp_t 4 Acceleration/deceleration time constant with S command (Gear: 11)
(3) Spindle speed settings for Z-phase detection when starting
At the first spindle rotation after the power ON (including turning the power ON again only for NC), the spindle
rotates at the speed of setting parameters during Z-phase detection for the encoder. Set the rotation speed.
#3106 zrn_typ Zero point return specifications
bit F : Spindle zero point detection with contactless switch
0: Normal 1: Enable spindle zero point detection using proximity switch
#3109 zdetspd Z phase detection speed
For the first S command after power is turned ON, the spindle rotates at the speed of setting value
for this parameter until Z phase is detected twice.
When "#3106/bitF = 1" (Spindle zero point proximity switch detection enabled), also proximity switch
is detected.
(Note) When spindle zero point proximity switch detection is enabled, the rotation direction of the
orientation/zero point return (synchronous tapping, spindle/C axis) will follow Z phase detection
direction. And the speed will follow Z phase detection speed.
---Setting range---
1 to 99999 (r/min)
(4) Parameters set depending on the connected NC
#13230 SP230 SFNC10 Spindle function 10
bit 8 : nohis History of communication error alarm between NC and DRV(34,36,38,39)
For C70, set "1".
0: Enable 1: Disable
< Initial parameters set depending on the machine specifications >
Set the following parameters depending on the spindle drive method (direct, gear drive, etc.) or inertia size of rotary
sections for machine specifications.
(1) Adjustment parameters in orientation mode
When the inertia ratio is large for the spindle motor such as large lathes, set the following parameters so that
abnormal noise or machine sway does not occur during orientation control.
