MDS-D-SVJ3/SPJ3 Series Instruction Manual
3-3 Setting the initial parameters for the spindle drive unit
【#13020(PR)】 SP020 RNG2 Main side detector resolution
Set the number of pulses per revolution of the main side detector.
When using the serial changer MDS-B-HR, use this with SP098(RNG2ex).

When using SP098: (p/rev)
【#13021(PR)】 SP021 OLT Overload detection time constant
Set the detection time constant of Overload 1 (Alarm 50). (For machine tool builder adjustment)
Normally, set to "60".
Set to "300" when using an IPM spindle motor.
---Setting range---
1 to 15300 (s)
【#13022】 SP022 OLL Overload detection level
Set the current detection level of "Overload 1" (Alarm 50) as a percentage against the motor short-
time rated output current. (For machine tool builder adjustment)
Normally, set to "120".
Set to "100" when using an IPM spindle motor.
---Setting range---
1 to 200 (Short-time rated %)
【#13023】 SP023 OD1 Excessive error detection width (interpolation mode - spindle
synchronization)
Set the excessive error detection width for the interpolation mode and spindle synchronization.
The standard setting is "120".
When set to "0", the excessive error detection will not be performed.
---Setting range---
1 to 32767 (°)
【#13024】 SP024 INP In-position width
Set the in-position detection width.
Set the positioning accuracy required to the machine.
Lower setting value increases the positioning accuracy, but makes the cycle time (settling time)
longer.
The standard setting is "875".
---Setting range---
0 to 32767 (1°/1000)
