Functional Features:
- Fully integrated drive + motor — no external drive cabinet required
- EnDat 2.2 absolute encoder — zero-homing on power-up
- Built-in brake (B suffix) — holding torque when unpowered
- Web server diagnostics — real-time temperature, current, vibration monitoring
- Electronic gear ratio — up to 1:10000
- Safe Torque Off (STO) — integrated safety function
Structural Features:
- Compact 60mm cylindrical body with integrated electronics housing
- Smooth shaft (no keyway) — use clamping hub for zero-backlash coupling
- IP65 sealed — washdown capable
- M23 connector for power, feedback, and I/O (single cable)
Working Principle: Integrated inverter drives the PMSM with sinusoidal commutation. EnDat encoder provides absolute position feedback. All servo loops (current → velocity → position) execute within the motor housing. EtherCAT/CANopen provides host communication.
Advantages:
- Eliminates external drive — reduces wiring, cost, and panel space by 40%
- IP65 rating — direct washdown without additional enclosure
- Absolute encoder — no homing routine required
- Integrated brake — no external brake module needed
- Smart diagnostics — predictive maintenance via web interface
Applicable Industries:
- Food & beverage (washdown environments)
- Pharmaceutical (cleanroom-adjacent)
- Light packaging machines
- Medical devices (lab automation)
- Agricultural equipment (sprayers, harvesters)
Installation Requirements:
- Mount using M4 through-bolts on 60mm flange pattern
- Use clamping hub coupling (recommended: 14mm bore, 4mm clamping range)
- Single M23 cable carries power + feedback + I/O — max 10m
- Ground chassis to protective earth
Usage Notes:
- Do not exceed 240V AC input — overvoltage destroys integrated drive
- Brake requires 24V DC supply (terminals provided on M23)
- Update firmware via EtherCAT or USB for latest features
- Thermal derating applies above 40°C ambient — reduce continuous torque by 10% per 10°C
