Delta Tau ACC‑24E2A4‑AXIS

Operating temperature ranges from 0°C to 45°C; storage temperature ranges from ‑25°C to 70°C; relative humidity maintains 10%‑95% non‑condensing. Physical dimension is 162.56 mm × 100 mm × 20.3 mm. Power is supplied from UBUS backplane. Command output supports ±10 V analog velocity/torque signal and pulse‑direction signal. Encoder input accepts differential and single‑ended TTL A/B/Z incremental encoder signals. Each axis provides 8 digital flag inputs and 2 digital flag outputs. Maximum 4 servo axes per single board. Communication interface adopts high‑speed UBUS backplane busManualsLib.

Supports mixed control modes of analog voltage and pulse‑direction. Equipped with encoder loss detection function. Configurable differential/single‑ended encoder input through hardware jumper. Built‑in limit switch and flag signal processing circuit. Deterministic real‑time data transmission via UBUS backplane. Supports fault status feedback for each axis. Multiple cards can be stacked for axis quantity expansion. Compatible with most third‑party analog‑interface servo drives.

Multi‑axis CNC machine tool control, semiconductor manufacturing equipment, multi‑joint robotic systems, automated assembly equipment, high‑speed packaging machinery, precision positioning platforms, and other industrial equipment requiring multi‑axis synchronous motion control.

Servo clock can be configured by jumper setting. Encoder input frequency supports high‑speed incremental encoder feedback. Analog output accuracy matches PMAC2 motion control IC performance. Digital flag input works within 5 V‑24 V signal level range. System realizes microsecond‑level motion control cycle after backplane connection.

FR‑4 printed circuit board, gold‑plated backplane connector, metal front panel with locking screw, industrial‑grade surface‑mount integrated circuits, terminal block connectors, through‑hole signal conditioning components, and EMC filtering components.

Standard 3U Eurocard form factor, single‑slot rack installation without option upgrade. Metal front panel with indicator windows and fixing screws. UBUS 96‑pin backplane header for internal controller communication. External signal is led out via removable terminal blocks. Piggyback sub‑board can be stacked to activate third and fourth axis channels, occupying two rack slots after installation of sub‑board.

The board receives motion trajectory commands from UMAC main controller through UBUS backplane bus. The onboard PMAC2‑style servo IC converts digital motion instructions into ±10 V analog command or pulse‑direction signal and sends them to external servo drives. Encoder position feedback signal from motor returns to this board, and feedback data is transmitted back to main controller for position closed‑loop calculation. Digital limit and flag signals are sampled and uploaded to motion CPU for logic judgment and safety interlock execution.

Install into standard 3U industrial rack and insert firmly into UMAC backplane slot. Tighten front‑panel locking screws to ensure reliable mechanical fixation. Configure hardware jumpers to select encoder signal mode and clock setting before power‑on. Complete wiring of servo command cable, encoder cable and limit‑flag signal cable. Confirm backplane power supply specification matches module requirement. ESD protection operation must be performed during installation. Avoid installing in positions directly adjacent to high‑power inverter modules to reduce electromagnetic interference.

Do not hot‑swap the module under powered‑on state. All signal wiring shall use shielded cables. Keep analog signal wiring away from high‑current power cables. Verify jumper configuration before power‑on to prevent hardware damage. Set axis assignment parameters in PMAC software after hardware installation. Check encoder power supply load capacity when connecting external encoders. Conduct full‑scale signal test after wiring completion. Operate within specified temperature and humidity range.
