Delta VFD Inverter Series

Delta organises its inverter range across several platforms, from entry V/f to high-performance closed-loop vector.

VFD-EL — Entry-Level Single/Three-Phase

The VFD-EL is Delta's most affordable inverter — compact, lightweight, and suited to simple V/f speed control of fans, pumps, and small conveyors. Single-phase 240 V input models are available for motors up to 2.2 kW, making the VFD-EL the most common drive used in Malaysian SME workshop equipment, small ventilation fans, and basic conveyor drives.

Key specifications: V/f control mode, RS-485 Modbus RTU, built-in EMC filter option, DIN-rail mounting. No encoder feedback capability.

• VFD007EL21A: 0.75 kW, single-phase 240 V input, three-phase 220 V output. Priced from approximately RM 280 – RM 450.
• VFD022EL43A: 2.2 kW, three-phase 380–480 V. Priced from approximately RM 500 – RM 700.

VFD-M — General-Purpose Mid-Range (Legacy)

The VFD-M series was Delta's primary general-purpose inverter before the MS300 replaced it as the current-generation mid-range product. VFD-M units remain in widespread Malaysian service — maintenance spare parts and replacement units are sourced regularly by local factories. Flextech Industrial stocks VFD-M for replacement and repair support.

MS300 — Current-Generation General Purpose

The MS300 is Delta's current-generation general-purpose inverter — the replacement for the VFD-M and the correct specification for new designs. MS300 delivers sensorless vector control with auto-tuning, built-in Modbus RTU (RS-485) and optional Modbus TCP/EtherNet/IP, and a compact DIN-rail form factor.

The MS300 auto-tune function allows the drive to measure motor parameters (stator resistance, inductance) at startup and optimise vector performance without manual parameter entry — a significant time saver in Malaysian panel building and commissioning environments.

• MS300-021-0.4K: 0.4 kW, three-phase 200 V. Priced from approximately RM 500 – RM 800.
• MS300-021-7.5K: 7.5 kW, three-phase 200 V. Priced from approximately RM 2,000 – RM 3,500.
• MS300-023-22K: 22 kW, three-phase 380–480 V. Priced from approximately RM 6,000 – RM 9,000.

ME300 — Micro Drive (Space-Constrained Applications)

The ME300 is Delta's compact micro drive — smaller than the MS300 in every dimension, suited to machine installations where panel depth is under 90 mm. Popular in conveyor sub-panels, machine tool spindle drives, and OEM machine builder designs where panel volume is a design constraint.

VFD-VE — Closed-Loop Vector (High Performance)

The VFD-VE supports closed-loop flux vector control with optional encoder feedback card. Speed regulation reaches ±0.02% of set speed at full load; starting torque achieves 200% at zero speed. This performance level suits winding and unwinding applications, speed-controlled cranes, and precision conveyor synchronization in Malaysian paper, film, and wire drawing operations.

C2000 / C2000 Plus — Heavy-Duty High Power

The C2000 is Delta's high-power industrial drive for applications above 22 kW requiring fieldbus integration and advanced motor control. C2000 Plus supports EtherNet/IP, PROFIBUS, CANopen, and BACnet — making it the Delta choice for Malaysian water treatment plants requiring BACnet integration and large factory SCADA systems using EtherNet/IP.

Delta VFD and PLC Integration in Malaysia

Delta inverters integrate with PLCs via three standard methods used in Malaysian automation:

RS-485 Modbus RTU: All Delta VFD models (VFD-EL, MS300, C2000) include RS-485 Modbus RTU as standard. One Modbus master (Mitsubishi FX5U, Siemens S7-1200, Omron CJ2M) polls up to 32 drives on one RS-485 bus — reading motor current, frequency, fault code, and writing speed setpoint. This is the dominant integration architecture in Malaysian F&B and manufacturing conveyor lines.

Analogue Reference (0–10 V / 4–20 mA): Direct from PLC analogue output to Delta drive frequency reference input. Simple, no protocol configuration required. Used where Modbus infrastructure is not available.

EtherNet/IP / Modbus TCP (MS300, C2000 with option card): For Delta drives in SCADA-supervised systems, optional communication cards add Modbus TCP, EtherNet/IP, CANopen, or PROFIBUS. The C2000 supports these natively; MS300 requires an option card (CMC-EIP01 for EtherNet/IP).

Delta Inverter Applications in Malaysian Industry

F&B Conveyor Lines (Selangor, Johor): Delta MS300 is the most frequently specified Delta drive in Malaysian food and beverage conveyor lines — its sensorless vector auto-tune and compact size suit new machine panel designs. The VFD-M is the service and replacement standard for existing F&B installations.

Water Treatment (Nationwide): Delta CP2000 pump drives with PID control and fire-mode input are deployed in Malaysian water treatment and pumping station applications. The built-in pressure PID loop eliminates the need for a separate PLC in simple pump pressure control.

Textile and Rubber (Selangor, Perak): Delta VFD-VE closed-loop vector drives handle winding tension control in tyre cord and rubber thread production equipment in Selangor and Perak industrial estates.

SME Machinery Retrofit: The Delta VFD-EL is the most affordable genuine industrial inverter available in Malaysia — widely used in SME workshops for retro-fitting fixed-speed motors on drill presses, grinders, and small conveyors. Malaysia's Smart Automation Grant (SAG) covers inverter retrofits that include network communication.

Frequently Asked Questions

What is the most popular Delta inverter in Malaysia?

The Delta MS300 is the current best-selling Delta inverter in Malaysia for new designs. For maintenance and replacement, the Delta VFD-M and VFD-E remain the most commonly serviced units across Malaysian factories due to their long installation base. Flextech Industrial stocks both current-generation (MS300) and legacy replacement (VFD-M, VFD-E) units.

How do I configure Delta VFD Modbus RTU communication?

Set the following parameters on the Delta MS300 for Modbus RTU communication: P9-00 (communication address, 1–254), P9-01 (baud rate, e.g., 3 = 9600 bps), P9-04 (communication protocol, e.g., 0 = 8N1 Modbus RTU). On the PLC Modbus master, write to register 2001h to set frequency and 2000h for run command. The Delta VFD-M uses different register addresses — consult the model's user manual.

What is the price of Delta MS300 in Malaysia?

Delta MS300 inverters in Malaysia are priced from approximately RM 500 (0.4 kW) to RM 20,000+ (75 kW). Mid-range models (2.2–7.5 kW) most commonly used in Malaysian conveyor and pump applications are priced from RM 700 – RM 3,500. Contact Flextech Industrial for current MYR pricing.

Is Delta a good inverter brand for Malaysia?

Delta Electronics is a reputable Taiwanese industrial automation brand with ISO 9001 certification and a strong Malaysian distribution network. Delta VFDs are genuine OEM products — not to be confused with grey-market copies that circulate on local online marketplaces. Flextech Industrial sources Delta inverters directly through authorised channels, ensuring genuine product quality and warranty support.

Can I use a Delta inverter with a Mitsubishi PLC in Malaysia?

Yes. Delta VFDs support Modbus RTU communication over RS-485, which is compatible with Mitsubishi FX3U, FX5U, and iQ-R PLCs using the built-in RS-485 port (FX5U) or FX3U-485ADP-MB expansion adapter. The Mitsubishi PLC acts as Modbus master, reading Delta VFD status registers and writing speed/direction commands using Modbus IVBFR or TO/FROM instructions.
