2. Electrical Specifications
DC Bus Input Voltage: 283–325 VDC
Rated Input Power: 3.7 kW
Output Voltage: 230 VAC (3‑phase, per axis)
Rated Output Current (per axis): 5.9 A (continuous)
Number of Axes: 3 (L‑axis / M‑axis / N‑axis)
Control Method: FSSB fiber‑optic serial communication
Cooling: Forced air cooling (internal fan)
Operating Temperature: 0 °C to +55 °C
Protection: Overvoltage, undervoltage, overcurrent, overtemperature, short circuit
3. Connector Layout
CXA2A / CXA2B: 24 VDC power & battery backup (for absolute encoder)
FSSB IN / OUT: Fiber‑optic ports (CNC ↔ amplifier ↔ amplifier)
CN1L / CN1M / CN1N: Motor encoder feedback (per axis)
CN2L / CN2M / CN2N: Motor power (U/V/W, per axis)
DC Bus: P(+), N(−), regenerative resistor terminals
Ground: Protective earth (PE)
4. Compatibility
CNC Systems: 0i‑D, 0i‑MF/TF, 30i/31i/32i‑B (FSSB interface)
Servo Motors: αiS, αiF, αiC series (200 V class, 3/2000 motors)
Regen Resistor: FANUC standard external regenerative resistor
Battery: A06B-6093-K001 (for absolute encoders)
5. Key Features
Three‑axis control: 3 axes in one compact unit (20/20/20 rating)
FSSB high‑speed serial bus: Reduces wiring, improves noise immunity
Compact design: 90 mm width saves cabinet space
Absolute encoder support: Battery backup via CXA2A/B
Built‑in diagnostics: Fan monitoring, overcurrent detection, alarm codes
6. Notes
For 200 VAC motor systems only (not 400 V HV series)
Requires FSSB‑capable CNC (no analog/pulse interface)
Typical alarm codes: Fan stop (1), low 5V (2), DC link undervoltage (5), axis overcurrent (8/A)
