4.3 Setting the Initial Parameters for the Spindle Drive Unit

The spindle specification parameters and spindle parameters must be set before the spindle system can be started up.
The spindle related parameters are input from the NC. The input method differs according to the NC being used, so refer
to each NC Instruction Manual.

4.3.1 Setting of Parameters Related to the Spindle

The spindle specification parameters "#3001-#3138" and spindle parameters "#13001-#13256" must be set before the
spindle is started up. Set the parameters depending on the spindle motor equipped to the machine and the machine
specifications. The following parameters must be set for startup, so check the setting values.
< Common parameters set for starting >
Set the command time constant etc. up to the maximum rotation speed of the spindle end and the maximum rotation
speed of the motor.
Especially the maximum rotation speed should be set not to exceed the machine specifications. In addition, acceleration/
deceleration of the spindle is executed with the constant torque control, so the time depends on the inertia size.
(1) Setting of the maximum rotation speed
Set the maximum rotation speed of S commands (synchronous tapping, etc.).
【#3001】 slimt 1 Limit rotation speed (Gear: 00)
Set the spindle rotation speed for maximum motor speed when gear 00 is selected.
Set the spindle rotation speed for the S analog output=10V during analog spindle control.
---Setting range---
0 to 999999 (r/min)
【#3005】 smax 1 Maximum rotation speed (Gear: 00)
Set the maximum spindle rotation speed which is actually commanded when gear 00 is selected.
Set this as smax1(#3005)<= slimit1(#3001).
By comparing the S command value and the values of gear 1 - 4, a spindle gear shift command will
be output automatically.
---Setting range---
0 to 999999 (r/min)
(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)
