Core functions (five general capabilities)

P+I closed-loop control: Position / Speed / Pressure, choose one of the three

Multi-valve direct drive: ±150mA output, compatible with ±10mA to ±150mA coils

Configurable jitter (Dither): 25–300Hz, amplitude adjustable from 0–40%

Slope generator: 0.5–20V/s, prevents shock

External enable / alarm relay: 24Vdc control, 1A contacts

Command input: ±10Vdc (impedance 100kΩ)

Feedback input: ±10Vdc (position / speed / pressure)

Output current: ±150mA continuous (peak ±200mA)

Frequency response: −3dB > 800Hz (with 1H inductor load)

Compatible servo valves (high versatility)

✅ D660 series: D661/D662 (Injection molding / die-casting universal)

✅ D633/D634 direct drive valves: D633-313A, D634-319C, etc.

✅ 72 series low-flow: D072-017 (Requires jumper to change current)

✅ Other ±10…±150mA coil servo valves

⚠️ Cannot directly replace D122-034-017C:

034 is for injection molding machines (speed + pressure dual closed-loop, dedicated pins);

F022 is a universal single-loop, with different pin definitions and cannot be directly interchanged.

Panel and debugging (similar to 034, but with different function areas)

Adjustable potentiometer (R×12): P gain, I time, zero point, bias, jitter, slope

Jumper (J×10): Valve current type, closed-loop type, enable logic, jitter switch

LED (×5): ±15V, command, feedback, output, alarm

Test points (TP×15): Oscilloscope monitors waveforms at each node

Typical applications (general industrial)

CNC machine tools: spindle, tool turret, feed axis hydraulic servo

Hydraulic station: proportional directional valve, pressure valve, flow valve control

Testing equipment: material testing machine, fatigue test bench, servo actuator

Non-standard automation: synchronous lifting, tension control, precise positioning
