Technical Specifications
Supply 24 V DC plus minus 10 percent, 125 mA typical. Isolated multi-channel SCR or IGCT gate pulses. 16-bit ADC feedback conditioning. Outer diameter 210 mm, thickness 32 mm. Weight 0.39 kg. Operating temperature -25 to plus 70 C linear derate above 65 C. Storage -40 to plus 75 C. Heavy-duty full acrylic conformal coat thicker than CE101. Fault lockout faster than R0001. Gold contact ring, LED per channel, power ok, multistage fault.
Functional Features
Reinforced EMI filtering. Optimized DTC sampling timing to reduce torque ripple. Faster overcurrent lockout lowers stack failure risk on heavy mill or hoist load. Thicker coat resists dust, humidity and corrosion in mine, cement and offshore cabinets. Drop-in mechanical and connector compatible with R0001.
Application Scenarios
Mining grinding mill MV drives. Cement kiln and crusher drives. Offshore ACS880 stacks. Hoist and overland conveyor heavy torque loops. Variable-load compressor and pump drives.
Material and Structure
Same circular PCB geometry as CE101, gold contact ring, added filter components, heavier conformal coat, identical mounting holes and heatsink contact profile.
Working Principle
Functionally identical signal path to R0001, with tighter analog filtering, shorter fault decision latency and improved dv or dt immunity on gate drive rails; optical receive, isolated pulse amplify, feedback sample, fault compare, optical return.
Installation Requirements
Same heatsink ring drop-in as R0001, reuse torque values, separate optical sync from power conductors, acknowledge revision ID in DriveWindow after swap, confirm cooling airflow before energize.
Usage Notes
Electrically and mechanically backward-compatible with R0001 slot. Drive firmware may log a revision change alarm, clear it in DriveWindow. Do not mix R0001 and R0003 on different phases of same stack unless ABB confirms homogeneous stack firmware.
