✅ Replacement & Compatibilitate

Same-series alternative: ALPHA6000E-S2R75GB (6000E is standard version; 6000M is mini version. Pinout and dimensions differ, not direct plug-and-play)

Domestic equivalent models: Inovance MD200, Invt GD10, Delta VFD-M single-phase 220V 0.75kW models

Full Technical Package for ALPHA6000M-S2R75GBRSM

1. Main Circuit Terminals (S2R75GB, single-phase 220V)

Critical warning: Never connect L/N to U/V/W, this will destroy the inverter immediately; PB and + can only be connected with braking resistor, short-circuit is forbidden.

2. Terminale ale circuitului de control (S2R4GB ~ S2R75GB)

Common Wiring Schemes

1. Potentiometer speed + terminal control: Potentiometer to 10V, AI1, GND; short X1-COM = forward run
2. 485 comunicare: 485+ to A, 485to B; add termination resistor on remote side if needed
3. Relay fault signal: TA-TC to PLC fault input
4. Factory Reset Procedure (ALPHA6000M / 6000E compatible)
5. Porniți, press PRG to enter parameter menu
6. Locate P0.02 (parameter initialization)
7. Setting options:

0: Nicio acțiune

1: Clear fault records

2: Restore factory defaults (recomandat)

4. Confirma, wait for auto-reset. Power cycle to take effect

Frequently used basic parameters:

P0.01: Control mode 0=V/F, 2=open-loop vector (vector recommended)

P0.07: Run command source 0=keypad, 1=terminals, 2=communication

P0.03: Frequency reference source 0=keypad, 2=AI1, 8=multi-speed, 10=PID

P0.10: Max output frequency, implicit 50 Hz, up to 650Hz

⚠️ Resistance below 100Ω will damage the built-in braking transistor. Mount resistor away from other components with sufficient clearance; resistor housing must be grounded.

Cablaj: Connect resistor two wires directly between + and PB, not the “-” Terminal.

5. Equivalent Replacement List (single-phase 220V 0.75kW mini vector, built-in braking unit preferred)

Nota: ALPHA6000M is mini type. Pinout and mounting holes differ from 6000E standard version, cannot be swapped directly

Alternative interne

5. Win-V63 0.75kW 220V single-phase

Note de înlocuire

Priority check items: unitate de frânare încorporată, DI/DO quantity, AO 4-20mA support, Modbus RTU

Original unit: intrare monofazată, 3-phase 220V output. Replacement motor must be rated 220V 3-phase, cannot drive 380V motor directly

For easy parameter migration: ALPHA6000E-S2R75GB from same brand, but larger size and different mounting holes

6. Fault Code Quick Reference (6000M)

7. Motor Auto-Tuning (Mandatory for Vector Mode)
8. Set P0.01=2 (open-loop vector)

11. Confirm and start; auto-tuning finishes automatically

ALPHA6000M Multi-speed + PID Constant Pressure Water Supply Parameter Set

For ALPHA6000M‑S2R75GB (0.75kW single-phase 220V)

Nota: Do not activate both functions at once. PID is for constant pressure water / air supply; multi-speed is for assembly lines, packaging machines and multi-position fixed speed switching.

Schema A: Control cu ​​mai multe viteze (DI speed selection, terminal start/stop)

Logica de control

Command source: Terminal run

Frequency source: Cu mai multe viteze

DI assignment: X1 forward run, X2 reverse run, X3/X4/X5 as speed selectors (3-binar binar, până la 8 viteze)

COM is DI common terminal, NPN mode (factory PLC shorted with 24V)

Parameter List

Wiring Tips

No pressure / speed sensor required; only DI switch signals

If only 4 speeds are needed, use X3 and X4 only; X5 can be assigned to fault reset or other functions

Schema B: PID Constant Pressure Water Supply (Closed-loop, 4-20mA pressure transmitter)

For small pump pressure stabilization. 4~20mA transmitter to AI1; 4mA = lower pressure, 20mA = full scale pressure

Output of this inverter is 3-phase 220V. Pump motor must be 3-phase 220V type, not 380V pump motor

Logica de control

Command source: Terminal start (X1 forward run)

Frequency source: PID output

AI1: 4~20mA pressure feedback

PID setpoint: Keypad setting (or AI2 potentiometer setpoint)

Parameter List

Cablaj

Pressure transmitter: Powered by inverter 24V, signal+ → AI1, signal→ GND

Set AI1 DIP switch to current mode (4-20mA)

Short X1-COM to start; open to stop

PID Tuning Sequence (Important)

1. Disable PID first (P5.00=0), run pump manually to confirm rotation direction
2. Confirm transmitter range: de ex. 0~1MPa, P6.01=0, P6.02=1.0
3. P5.00=1 to enable PID, set target pressure on keypad e.g. 0.4MPa
4. Depanare:

Pressure oscillates: Reduce Kp (de ex. la 15), increase Ti

Pressure rises slowly: Increase Kp, reduce Ti

Severe overshoot: Reduce Kp, increase Ti

5. Funcția de somn (P5.09=1): At low flow, when pressure exceeds setpoint for a period, inverter drops to min frequency then stops; restarts when pressure drops below wake-up threshold. Suitable for small water systems.

Switching Tip

Cu mai multe viteze: P0.03=8

PID constant pressure: P0.03=10

Change P0.03 and power cycle inverter for best stability.
