| Parameter | Description | Notes | | :--- | :--- | :--- | | | Spindle max speed | In min⁻¹ (RPM). | | SP006-009 | Gear selection method | 0 = M41-M44, 1 = auto gear range. | | SP018-021 | Gear ratio numerator (each gear) | Example: 1:1 → 1. 2:1 → 2. | | SP022-025 | Gear ratio denominator | Example: 1:1 → 1. 2:1 → 1. | | SP041 | Orientation stop position | In degrees (0-359.999). | | SP083 | Spindle motor series code | Must match actual spindle motor. | | SP117 | Rigid tapping (0=off, 1=on) | Requires option hardware. |
| Parameter | Description | Typical Range | Tuning Guide | | :--- | :--- | :--- | :--- | | | Position loop gain | 20-300 rad/s | Higher = more responsive. Start at 30. Increase gradually. | | SV002 | Speed loop gain | 20-1000 rad/s | Set ~2-4x position gain. | | SV003 | Speed loop integral time constant | 10-200 ms | Lower = stiffer. 40-80 typical. | | SV004 | Feedforward gain | 0-100% | 0% = no FF. 30-70% reduces following error. | | SV006 | Torque filter time constant | 0-2500 µs | Reduces noise. 100-500 typical. | | SV012 | Load inertia ratio | 1-2000% | Critical for performance. Use auto-tuning first. | | SV031 | Overshoot detection level | 0-200% | 100% typical. Reduce to 50% for safety. | | SV083 | Motor series code | (Read only) | Verify matches actual motor type. |
