Key Features:

• No-key shaft with clamping hub eliminates keyway backlash — zero lost motion for precision applications
• 17-bit single-turn absolute encoder (131072 counts/rev) provides sub-arc-second resolution
• Short stack (02) configuration minimizes rotor inertia for highest acceleration bandwidth in S700 frame
• 750 W continuous power at 48 VDC bus — high power density in 115 mm flange
• BiSS-C encoder with CRC error detection ensures data integrity in noise-heavy environments

Applicable Industries: High-Speed CNC Spindles, Semiconductor Wafer Handling, Print Roll Drives, Robot Joint Actuators, Packaging Line Servos

Installation Requirements:

• Mount using 4x M5 bolts on 95 mm bolt circle, torque to 4.0 Nm
• Shaft coupling: Use clamping hub coupling (e.g., Kollmorgen Zero-Backlash Clamping Hub), torque to 8 Nm
• Encoder cable: Use Kollmorgen shielded M23 cable, route away from power cables (min 100 mm separation)
• Thermal: Mount to heatsink or cold plate for continuous operation above 50% rated torque

Usage Notes:

• No-key shaft requires clamping hub — do not use set-screw couplings (will damage shaft)
• 17-bit encoder requires EtherCAT with BiSS-C master (AKD drive supports this natively)
• Do not exceed 48 VDC bus voltage
• Derate torque by 0.8% per °C above 25°C case temperature
