⚠️ Selection & نقاط التثبيت الرئيسية

1. This 460V model can be directly applied to domestic 380V power grids. Distinguish between heavy duty / light duty during selection. For 280kW heavy-duty loads, selection must be based on 550A current rating instead of power only.
2. IP00 rating: Never install exposed outside cabinet. For dusty or humid sites, use independent air-conditioned control cabinets.
3. لا توجد وحدة فرامل مدمجة: External braking unit + braking resistor are mandatory for high-inertia or fast-stop applications.
4. Standard DC reactor reduces line-side harmonics; an external EMC filter is required if EMC compliance is needed.
5. Supports motor auto-tuning (stationary / rotating identification); parameter identification is required for permanent magnet motors.

🚨 Common Fault Troubleshooting (C2000 High-power Models)

OCC: Output short circuit, cable earth breakdown, IGBT damage. For high-power units, prioritize checking output contactors and motor insulation.

OV: Excessive regenerative energy, missing braking unit; deceleration time is too short.

رأ: الزائد للمحرك, current transformer drift, inaccurate auto-tuning parameters.

أوه: Blocked air duct, aged cooling fan, poor cabinet heat dissipation (highly frequent for high-power cabinet models).

LF: Output phase loss, loose cable terminals, broken motor winding.

Motor Auto-tuning Parameter List (VFD2800C43A C2000)

Applicable for Induction Motor (أنا); 05-00=1 Rotating Auto-tuning (Recommended when motor can be decoupled and rotated); 05-00=2 Stationary Auto-tuning (Used if motor cannot rotate)

Pre-requisite Nameplate Parameters Entry

Auto-tuning Mode Selection (05-00)

05-00=1: Rotating Auto-tuning (Dynamic) [المفضل]

Decouple the motor from mechanical load; the shaft will rotate during operation. Automatically measures Rs, Rr, Lm, leakage inductance and no-load current. Highest vector control accuracy, suitable for extruders, ball mills, hoists and other heavy-duty equipment.

05-00=2: Stationary Auto-tuning

Used when the motor is coupled to load and cannot rotate. Only measures stator resistance Rs. Lower control accuracy than rotating auto-tuning; for emergency use only.

PM Permanent Magnet Motor: 05-00=4; Synchronous Reluctance Motor: 05-00=11

Auto-tuning Operation Steps

1. Safety check: Disconnect mechanical load, ensure free rotation with no jamming, release brake, keep personnel away from drive shaft. For 280kW high-power units, verify output cable and motor insulation.
2. Enter the above nameplate parameters.
3. 00-10 وضع التحكم: PG-less vector = 2; PG closed-loop =3.
4. Set 05-00=1 (Rotating Auto-tuning).
5. Press RUN on keypad; panel displays TUNE and auto-executes. Auto-tuning completes when TUNE disappears.
6. Verify calculated results and check identified parameters:

05-05: Motor no-load current

05-06: Stator resistance Rs

05-07: Rotor resistance Rr

05-08: Magnetizing inductance Lm

05-09: Leakage inductance Lx

7. Save parameters, power cycle the drive.

⚠️ Notes for failed rotating auto-tuning: Motor not decoupled, brake not released, overlong cables, عزل ضعيف, incorrect nameplate entries.

Master-Slave Parallel Drive Commissioning Steps (C2000 Multi-drive Parallel, Fiber Optic Parallel Scheme, VFD2800C43A)

طلب: مزدوج / multi-motor coaxial drive (belt, rolling mill, extruder). Fiber optic parallel option card (accessory) supports torque sharing. Master receives speed command, slaves follow torque distribution.

Rule: Motor parameters and protection settings must be identical for master and slave drives. Only the master sends speed commands; slaves receive fiber synchronization signals.

Hardware Preparation

1. Install C2000 fiber optic parallel communication card for each inverter; connect master to slave via fiber patch cords in daisy chain topology for multi-drive systems.
2. Complete individual motor auto-tuning for each drive first (commission each unit standalone before parallel operation).
3. Output contactors of master and slave must close simultaneously; asynchronous closing is forbidden.
4. مزود الطاقة: Separate incoming power or common DC bus. For common bus scheme, pay attention to DC bus voltage balancing.

Parameter Configuration

يتقن

1. 00-62 = 1 (Master mode)
2. 00-10 = 0 【Speed control mode, parallel function only supports speed mode】
3. 00-17 Carrier frequency: ≤6kHz recommended for high power
4. 00-64 = 8 (bit3=1, enable parallel start)
5. مجموعة 05 motor parameters filled according to motor nameplate; standalone auto-tuning completed
6. Acceleration / deceleration time 01-12/01-13 set to match mechanical inertia
7. Protection parameters (الزائد, التيار الزائد, الجهد الزائد) identical to slave drives
8. 00-62 = 2 (Slave mode)
9. مجموعة 05 motor parameters, protection parameters and carrier frequency must match master exactly
10. Command source: 00-21 = 6 (Fiber parallel command)
11. Frequency reference: 00-20 = 9 (Fiber parallel reference)
12. 11-00 =9 Enable master-slave torque distribution

Step-by-step Commissioning Procedure

1. Individual commissioning: Master and slave run separately with decoupled load, complete auto-tuning, test no-load operation and confirm no faults and normal current.
2. خارج السلطة, wire fiber links, check firmware version of fiber card (view via 00-63).
3. Input all master/slave parameters, power cycle all inverters.
4. No-load linkage test: Run command to master, slaves start synchronously. Control no-load current difference within 5%.
5. Gradual loading: Increase load step by step, monitor output current of both inverters. Target: Equal current sharing.
6. Fine-tune torque compensation parameters (مجموعة 11): Adjust 11-xx torque balance parameters when current deviation is large; avoid large modifications.
7. Limit test: Full load and emergency stop test, check OV, OL faults. Confirm braking unit capacity for high inertia loads.

Common Master-Slave Parallel Issues

1. Large current difference between two drives: Poor standalone auto-tuning, inconsistent motor parameters, loose fiber connectors, poor mechanical coaxiality.
2. Startup jitter: Excessively high carrier frequency, reduce 00-17; acceleration/deceleration time too short.
3. Fiber communication fault: Inspect fiber end face, fiber card, wiring sequence, do not swap Tx/Rx.
4. Parallel function only supports speed mode, pure torque mode parallel is not supported.

⚠️ Selection Remarks

1. Model coding note: In `VFD2800C43A`, 2800 = 280kW. The trailing two zeros are placeholders, not 2800kW, a common misinterpretation.
2. Heavy-duty HD current is the core selection criterion. Do not select based purely on kW rating. For ball mills, الرافعات, بثق, select according to heavy-duty current.
3. H/H1 frame (≥132kW): IP00 cabinet installation, built-in DC reactor. لا توجد وحدة فرامل مدمجة. External braking unit + resistor required for fast stop.
