LXM32MD72N4 SoMove Power-on Commissioning Parameter Template

ملائم: Lexium32M 7kW CANopen bus servo, matched with BSH/BMH 400V motors; SoMove software, expert mode password 696969

Pre-operation: Complete hardware wiring including power cable, التشفير, توقف الطوارئ, الفرامل, CAN bus and 24V control power supply; perform no-load jog test first, then auto-tune under load; save parameters to EEPROM after modification.

2. Axis Limit Parameters (Axis Configuration → Limitations)

3. الإدخال/الإخراج & Safety Parameters (Axis Configuration → IO)

4. Position Scaling (Scaling, Core for Positioning Projects)

User units per revolution, example: 10mm per revolution for lead screw, modify as required

| اسم المعلمة | Parameter ID | Example Value | وصف |

| —| —| —| —|

| Position Numerator | ScalePOSnum | 10 | Numerator of travel per revolution |

| Position Denominator | ScalePOSdenom | 1 | Denominator; example: 10mm/rev → 10/1 |

| Velocity Scaling | ScaleVELnum / ScaleVELdenom | Follow position | Velocity unit: مم/ثانية |

| Acceleration Scaling | ScaleACCnum / ScaleACCdenom | Follow position | Acceleration unit: mm/s² |

Raw encoder resolution: 16384count/rev for SinCos motors

5. Servo Loop Gains (Tuning Page, No-load → On-load Auto-tune)

Prioritize SoMove automatic inertia identification + auto-tune, then fine tune

| اسم المعلمة | Parameter ID | Initial Recommendation | Tuning Logic |

| —| —| —| —|

| Position Loop Gain | CTRL_Kp_pos | 3~8 | Higher for stiff mechanics; reduce if oscillation occurs |

| Speed Loop Gain | CTRL_Kp_vel | 80~150 | Base response, reduce for mechanical resonance |

| Speed Loop Integral Time | CTRL_Ti_vel | 8~20ms | Smaller value improves steady-state error, prone to oscillation |

| Velocity Feedforward | CTRL_Kff_vel | 0.6~0.9 | Reduce position following error |

| Acceleration Feedforward | CTRL_Kff_acc | 0~0.3 | For high-speed start-stop; large value causes impact |

| Low-pass Filter | CTRL_FiltVel | 500~1000Hz | Suppress resonance; lower filter frequency at resonance point |

8. يراقب & Fault Log

Fault Buffer: Stores latest 16 alarms for troubleshooting of OV/OC/OH/ENC faults

راسم الذبذبات: Sample target position, actual position, following error, bus voltage, motor current for resonance and tuning analysis

Complete Power-on Commissioning Procedure (Matching Parameter Template)

1. Connect PC to drive RJ45 debug port via SoMove, establish communication and read factory parameters
2. Run Simply Start wizard, select motor model and confirm encoder type
3. Configure limit, brake and I/O terminal definition
4. Set position scaling and mechanical transmission ratio
5. Set CANopen Node ID, baud rate and configure PDO
6. No-load test: يُمكَِن, jog, verify rotation direction, limit and brake logic
7. On-load test: Run Auto-tune inertia identification to generate base gains
8. Observe following error and oscillation via oscilloscope, fine-tune 3-loop gains and filter
9. Homing test, point positioning test, acceleration/deceleration test
10. Save parameters to EEPROM and export .cxm backup file

Commissioning Precautions

1. Expert mode password 696969, enter expert mode to modify advanced parameters
2. Auto-tune must be performed with actual load; parameters tuned under no-load easily oscillate under load
3. Incorrect brake timing will directly cause axis falling; test brake function without load during first commissioning
4. CANopen bus: Enable terminal resistor only at the first and last device on bus, disable for intermediate nodes
5. For high-power LXM32MD72N4, check wiring of line reactor and braking resistor before first power-up

Optional Extended Parameters

المقاوم الكبح: BRK_R, BRK_P for external braking resistor resistance/power rating, bus overvoltage protection
