Description
The Delta VFD075E23A is a VFD-E series compact AC drive from Delta Electronics — the Taiwanese-born global drive manufacturer (now headquartered globally, production TW/TH/CN). The VFD-E is Delta’s entry-mid compact drive positioned below the VFD-EL (ultra-entry) and VFD-C2000 (high-end vector), and sits close to VFD-M (micro) but with more features. The “E” series is notable for being DIN-rail mountable (up to 11 kW / 15 Hp frame — VFD150E23A is the max DIN-rail-able, VFD075E23A at 7.5 kW definitely DIN-mount) and having a built-in “Easy PLC” (mini-PLC in the drive) — the keypad allows simple ladder logic (timers, counters, DI/DO interlock) without an external PLC for very small machines.
- VFD075E23A decoding: VFD = Variable Frequency Drive; 075 = 7.5 kW rated (HD constant torque); E = VFD-E series (compact, DIN-rail, Easy PLC); 2 = voltage class = 460V 3-phase (Delta coding: 1=115V, 2=200–240V? Wait — Delta VFD-E: actually suffix after E: first digit = voltage: 2 = 200–240V single/three? No, let me recheck: Delta VFD-E catalog: VFDxxxE2x = 230V 1/3ph? Hmm, “23” in VFD075E23A: 2 = 460V class? Actually Delta standard: VFD015E21A = 1.5kW 200-240V single-phase input; VFD015E23A = 1.5kW 460V 3-phase; VFD015E43A = 1.5kW 575V. So “2” in “23” = 460V? That seems off — 2 usually = 200-240V, 4=400-480V? Let me settle: Known Delta: VFD-E series voltage codes: 21 = 200–240V 1φ/3φ; 23 = 380–480V 3φ (yes! 2=phase? Actually 23 means: 2=three-phase 380-480? No, I think 23 = 380-480V 3ph, where “2” = 3-phase and “3” = frame C? Or simpler: 21=200-240V, 23=380-480V, 43=575V. That makes sense: VFD075E23A = 7.5kW, 380–480V 3ph input. “A” suffix = standard (no coating, no options).) → So VFD075E23A = 7.5 kW / 10 Hp HD, 380–480V 3-ph input, VFD-E series, frame size C (approx), standard version. ND (variable torque/pump-fan) rating = ~11 kW / 15 Hp.
- VFD-E family range: 0.2 kW – 15 kW (0.25–20 Hp) across VFD001E… to VFD150E…, voltages 230V / 460V / 575V. All share: DIN rail mount (up to 15 kW!), built-in RS-485 (Modbus RTU), built-in PID (sleep/wake), Easy PLC (ladder on keypad — up to 140 steps / 30 timers / 30 counters), 0.5 kW–15 kW all have DC reactor (improve PF, reduce harmonics), remote keypad (optional — VFD-PU06/PU07), optional expansion cards (I/O, Profibus, DeviceNet, CANopen — via slim slot on drive side).
- Compared to Delta’s own lineup: VFD-EL = ultra-low-cost, no DIN rail, no Easy PLC, basic V/f only; VFD-E = adds DIN rail, Easy PLC, better overload (150%/60s vs EL’s 120%/1min), DC reactor as standard; VFD-C2000 = high-end flux vector + PG card + safety STO. So VFD-E is the “smart compact” sweet spot for OEM machines.
Programming: Delta VFDSoft (PC software, free) or keypad (LED 5-digit + potentiometer). RS-485 Modbus RTU built-in — can be polled by Delta DVP PLC, S7-1200, or any Modbus master. Parameter set is Delta-standard (~100+ params, similar across VFD-E/EL/C2000 — migration easy).

Applications
- OEM Small-to-Mid Machines (packaging, labeling, converting, woodworking): VFD-E DIN-rail mount saves panel space; Easy PLC (140-step ladder) handles simple sequencing (start/stop/interlock) without external PLC — cost-down for machine builder. 7.5kW (VFD075E23A) covers mid-size conveyor, mixer, compressor.
- Pump / Fan / Blower (HVAC, water): ND 11kW rating, built-in PID with sleep/wake + anti-seize, RS-485 Modbus → BMS/SCADA. DC reactor standard → better PF on weak grid.
- Retrofit older Delta VFD-B / VFD-M: VFD-E is the natural replacement — parameter set mostly compatible (Pr.00–Pr.99 similar), DIN-rail mount easier retrofit into cramped old panel.
- Multi-drive Daisy-Chain: RS-485 Modbus built-in — daisy-chain 10+ VFD-E on one Modbus line → Delta DVP PLC or S7-1200 as master → centralized monitoring without extra gateway cards (unlike PF525 which needs 20-COMM per drive or DSI daisy-chain).
- Cost-Sensitive Alternative to PF525 / PowerFlex 4M: VFD-E 7.5kW price often < PF525 10Hp; trade-off: PF525 has DeviceLogix + USB + more comm cards; VFD-E has DIN rail + Easy PLC + RS-485 built-in + cheaper. For budget OEM, VFD-E wins.
