MDS-D-SVJ3/SPJ3 Series Instruction Manual
3-3 Setting the initial parameters for the spindle drive unit
【#13120】 SP120 FSP5 Notch filter specifications 5
When not using, set to "0".
Set the target attenuation and damping coefficient of the notch filter.
To determine the value, multiply the damping coefficient by 10000, and add it to the absolute value
of the target attenuation -dB.
The setting range of each coefficient is as follows.
Damping coefficient: 0.01 - 1.00 (Increment: 0.01)
When "0" is set, the actual value to be set is 1.00.
Target attenuation: -80db - -1db (Increment: 1dB)
When "0" is set, the actual value to be set is -80.
E.g.: When the target attenuation is -40dB, and damping coefficient is 1.00
1.00×10000 + ABS(-40) = 10040
---Setting range---
0 to 32767
【#13121】 SP121 MP Kpp Magnetic pole detection position loop gain
Set the position loop gain in the magnetic polar detection loop.
This is used in the initial magnetic polar detection when the IPM spindle motor is turned ON.
Set to "0" when using an IM spindle motor.
---Setting range---
0 to 32767
【#13122】 SP122 MP Kvp Magnetic pole detection speed loop gain
Set the speed loop gain in the magnetic polar detection loop.
This is used in the initial magnetic polar detection when the IPM spindle motor is turned ON.
Set to "0" when using an IM spindle motor.
---Setting range---
0 to 32767
【#13123】 SP123 MP Kvi Magnetic pole detection speed loop lead compensation
Set the speed loop lead compensation in the magnetic polar detection loop.
This is used in the initial magnetic polar detection when the IPM spindle motor is turned ON.
Set to "0" when using an IM spindle motor.
---Setting range---
0 to 32767
【#13124】 SP124 ILMTsp Magnetic pole detection current limit value
Set the current limit value for the magnetic polar detection loop.
This is used in the initial magnetic polar detection when the IPM spindle motor is turned ON.
Set to "0" when using an IM spindle motor.
---Setting range---
0 to 999 (Short-time rated %)
【#13125】 SP125 DA1NO D/A output ch1 data No. / Initial DC excitation level
Input the desired data number to D/A output channel.
[When driving an IPM spindle motor (MDS-D/DH Series)]
Use in the DC excitation function.
DC excitation: Set the initial excitation level when SP225(SFNC5)/bit4(dcd)=1.
When "0" is set, the state will be the same as when "20" is set.
---Setting range---
-32768 to 32767
