Machine tools and compact automated equipment (ATV320 / ATV340)

Multi-drive daisy-chain networking to cut industrial switch costs

VIII. Troubleshooting Key Points

1. Steady red MS LED: Hardware fault, loose module insertion, mismatched drive firmware version
2. Steady red NS LED: No PROFINET device name assigned, IP address conflict, broken bus cable
3. Unlit port LNK indicator: Damaged Ethernet cable, poor crimp on RJ45 connector, powered-off remote device
4. Frequent communication packet loss: Non-shielded Ethernet cable, poor cabinet grounding, routing alongside power cables
5. Примечания по замене

No upgraded alternative within the same platform; VW3A3627 is the only original factory card for PROFINET applications.

No single-port PROFINET original card available; this dual-port model must be used if PROFINET connectivity is required.

Supported Drive Brands for Schneider VW3A3627

1. Sole Supported Brand: Шнайдер Электрик

The VW3A3627 is an original factory plug-in communication card exclusively designed for Schneider Altivar drives. Its hardware slot, underlying driver and power supply protocol are custom-made for Schneider drives. It is completely incompatible with all other brands including Siemens, АББ, Данфосс, Inovance and Delta, with no physical fit or matching communication firmware support.

1. Full Compatible Schneider Altivar Drive Series
2. Compact Machinery Range: ATV32 / ATV320

ATV32 (legacy low-power): Direct plug-in installation

ATV320-B variants: Equipped with native communication slot for direct insertion

ATV320-C variants: Require additional VW3A3600 adapter to mount this card

2. High-End Machinery-Specific ATV340

Compatible models: ATV340U07N4 ~ D22N4, ATV340D30N4E ~ D75N4E

Incompatible models: ATV340U07N4E ~ D22N4E (no expansion slot)

Exclusion: ATV340 Sercos dedicated versions do not support this card

3. General High-Power Process ATV600 Series

АТВ630, ATV650, Altivar Process Modular modular drives

4. Heavy-Duty High-Power ATV900 Series

ATV930, ATV950

III. Clearly Incompatible Legacy Schneider Drives

ATV12, ATV21, ATV212, ATV31, ATV312 (no VW3A36xx expansion slots; only legacy VW3A34xx DP cards are supported)

1. Critical Supplementary Notes
2. No cross-brand compatibility

Even if drives from other brands support the PROFINET protocol, differing hardware slots and backplane communication buses prevent installation of the VW3A3627, with no matching firmware drivers. Each brand supplies proprietary PROFINET cards: Siemens SINAMICS uses CBE20, ABB ACS uses FPNO-01, Danfoss VLT uses MCA120.

2. No brand restriction on PLC side

From a communication perspective, this card interfaces with all PROFINET IO-capable PLCs including Siemens, Инновации, Xinje and Rockwell. The only mounting host must be the aforementioned Schneider drives.

3. Installation prerequisite: Matching drive firmware version. Versions below the minimum requirement trigger a red MS hardware fault LED.

Complete Installation Guide for Schneider VW3A3627 PROFINET Communication Module

1. Mandatory Safety Pre-Installation Rules (Risk of Electric Shock / ESD Damage)
2. Full power cut-off & разряд конденсатора

Disconnect main drive power and 24V control power, apply lockout-tagout procedure. Wait 15 minutes to discharge DC bus capacitors; verify bus voltage is below 42 V with a multimeter before proceeding.

2. ESD anti-static protection

Wear an anti-static wrist strap or touch grounded cabinet metalwork to release static charge. Do not touch circuit board gold finger contacts with bare hands—static electricity can permanently damage the module.

3. Экологические требования

Cabinet free of dust and condensation; температура окружающей среды 0 ~ 50 °С. Keep clear of high-interference sources such as power cables and contactors.

4. Parts Checklist

Модуль: VW3A3627

Mandatory accessory for compact ATV320-C units: VW3A3600 communication adapter

Cabling: Industrial shielded CAT5e / CAT6 Ethernet cable (PROFINET standard)

1. Hardware Installation Steps by Drive Model

Модель 1: ATV320-B (Book-style, no adapter required)

1. Remove the dust cover from the front communication slot of the drive.
2. Align the module gold fingers with the slot and insert horizontally. Do not push fully home; the alignment mark confirms correct positioning.
3. Listen for the click of the locking clip to confirm the module is secured without play.
4. Removal: Press the PUSH clip below the module and pull steadily outwards.

Модель 2: ATV320-C / ATV320-W (Компактный / High-protection, adapter required)

1. Mount and lock the VW3A3600 adapter onto the side expansion port of the drive first.
2. Insert the VW3A3627 horizontally into the adapter slot; the clip locks automatically.
3. Removal: Press down the adapter PUSH clip and extract the communication card.

Модель 3: ATV340 / ATV630/650 / ATV930/950 (Процесс / Heavy-Duty High-Power)

1. Open the cover of the front expansion slot on the drive.
2. Align the module gold fingers with the backplane bus slot and push fully home.
3. Press the top module clip to lock securely with no wobble.
4. Removal: Pinch both side clips to release and pull the module straight out vertically.

III. Ethernet Cable Wiring Specifications (Dual-RJ45 Daisy-Chain Topology)

1. Определение порта: Port1 (uplink to PLC / switch), Port2 (downlink to next drive); integrated Layer 2 switch onboard.
2. Cabling: Fully shielded industrial Ethernet cable. 360° crimp the cable shield to the metal shell of both RJ45 connectors, with single-point cabinet grounding.
3. Wiring routing: Separate Ethernet cables from power cables with a minimum clearance of 30 см; cross cables perpendicularly where crossing is unavoidable.
4. Prohibited practices: Unshielded civilian Ethernet cables, ungrounded long cables, routing cables adjacent to contactors or drive output power cables.
5. Pre-Power-On Inspection Checklist
6. Module clips fully engaged with no loose or partially inserted state.
7. Gold finger contacts free of bending, oxidation or foreign debris.
8. RJ45 cable connectors fully crimped, aligned with LNK indicator lights.
9. All drive covers reinstalled for complete protection.
10. Reliable PE cabinet grounding with ground resistance ≤ 4 Ой.
11. Power-On Module Detection & Базовая конфигурация
12. Observe module LEDs after power-up:

MS LED: Module status (Green = Normal; Red = Hardware fault / Undetected)

NS LED: Network status (Green = Online; Red = No master station / IP conflict)

Port1/Port2 LNK: Steady on when cable connected; flashing ACT indicates data exchange

2. Activate communication card via drive parameters:

Navigate to parameter `COM.` → Select communication type as `PROFINET`

Import the corresponding GSD file into the PROFINET master PLC

Assign device name and IP address, complete hardware configuration

1. Installation Prohibitions (Strictly Forbidden Operations)
2. Hot plugging/unplugging the module (risks burning the backplane bus, module and drive main control board)
3. Touching circuit boards without anti-static protection
4. Forcing card insertion into ATV320-C units without installing the VW3A3600 adapter
5. Rough force or angled insertion bending gold finger contacts
6. Using unshielded Ethernet cables or leaving cable shields ungrounded
7. Leaving drive covers removed after module installation (dust ingress may cause short circuits)
