Product Description
The Omron R88DUA03LAAC100V is a dependable and lightweight 100 VAC servo driver for industrial use, delivering continuous 0.9 A and peak 2.8 A output, supporting 30 W motors, and operating within 100-115 VAC at 50/60 Hz. It offers precise position feedback via a selectable optical encoder (2,048 or 1,024 PPR), a broad 1:5,000 speed range, adjustable torque (1-10V DC) and speed (2-10V DC) commands, and PWM-based IGBT inverter technology operating at 11 kHz. It handles load inertia up to 30x rotor inertia (incremental) or 20x (absolute), maintains 0.2% temperature stability between 0C and 50C, and is suitable for robotics and motion control applications.
Is Your Device Showing These Signs?
The Omron R88D-UA03LA-AC100V servo drive commonly experiences issues such as resolver feedback errors, requiring resolver replacement or recalibration. Overcurrent faults are frequent, often stemming from shorted motor windings or IGBT failures within the power stage, necessitating motor testing and potential drive replacement. Communication errors on the EtherCAT network are addressed through firmware updates, cable inspections, and verifying proper network configuration. Inconsistent motor performance or jittering indicates encoder problems, demanding encoder repair or servo drive replacement. Overheating issues are resolved by checking the cooling fan functionality and ensuring proper heatsink contact.
