Delta Tau ACC‑24E2ADB16

Operating temperature 0°C‑45°C; storage temperature ‑25°C‑70°C; humidity 10%‑95% non‑condensing. Form factor is 3U Eurocard. Power supply comes from UMAC UBUS backplane. Command output: ±10 V analog velocity/torque signal, pulse‑direction signal. Encoder input: differential / single‑ended TTL A/B/Z signal. Each axis has 8 flag inputs and 2 flag outputs. Signal external connection passes through DB16 D‑Sub connectors. Maximum supported axes reach 4 after sub‑board installation. Complies with EN 61326 EMC standard.

Retains all core servo control functions of ACC‑24E2A series. Adopts DB16 multi‑pin D‑Sub connectors for centralized signal output. Supports hardware jumper switching of encoder signal mode. Built‑in encoder loss detection and limit signal processing. Watchdog safety circuit forces output to zero when communication fails. Supports system‑level fault diagnosis through PMAC script. Multiple modules can be deployed for multi‑axis expansion. Compatible with UMAC and MACRO‑Station controllers.

Industrial automation equipment using D‑Sub harness for servo connection, automated production lines, CNC processing equipment, testing equipment, multi‑axis positioning systems, robotic auxiliary axes, and retrofitting projects of legacy Delta Tau motion control systems.

Real‑time motion cycle is determined by UMAC main controller. Analog output maintains high linearity within full‑range output. Encoder input supports high‑speed incremental encoder signal. Digital flag signal accepts 5 V‑24 V discrete input. Watchdog circuit completes fault response within microsecond level.

3U rack‑mount structure. External signal interfaces are arranged on DB16 D‑Sub connectors on front edge of circuit board. Internal circuit connects to UMAC backplane via 96‑pin UBUS header. Piggyback sub‑board can be installed for 4‑axis expansion, occupying two rack slots. Metal front panel has fixing screws for rack fastening.

Motion instruction issued by UMAC main controller transmits to ACC‑24E2ADB16 through UBUS backplane. Onboard servo IC converts digital control instruction into analog or pulse‑direction drive signal, and outputs to servo drive via DB16 connector. Motor position feedback signal returns through DB16 connector to encoder input circuit. Feedback data is uploaded to main controller for closed‑loop position calculation. Limit and flag discrete signals are sampled and transmitted to motion CPU for safety interlock. Watchdog circuit monitors communication link status and triggers safe output state upon communication interruption.

Insert module into 3U slot of UMAC rack and lock front‑panel screws. Complete ESD protection measures before contact with circuit board. Configure jumper settings for encoder signal mode. Use matched DB16 harness cable to connect servo drive and encoder devices. Do not bend D‑Sub connector pins violently during plug‑in. Ensure reliable backplane contact. Keep sufficient ventilation space around the rack. Separate signal harness from high‑power power cables.

Hot‑swap is strictly forbidden under powered‑on status. Check pin definition of DB16 harness before power‑on to avoid short‑circuit damage. Shielded cables must be used for DB16 external harness. Set axis mapping parameters in PMAC software after installation. Periodically inspect D‑Sub connector contact condition. Operate within allowable temperature and humidity range. Complete signal and motion test before formal production operation.
