Product Description
The Allen-Bradley 1394-SJT22-T-RL Series C module functions as a GMC Turbo in 22 kW systems, offering higher power specifications than other 1394 family modules with a 28.6 Amp AC input current and a 324-528 Volt AC input voltage at 50-60 Hz. It features a 530-680 Volt DC nominal bus output voltage, a 697 Amp peak inrush current (limited to four contactor cycles per minute), a 17-22 kW continuous power output, 660 microFarad capacitance, and 98% efficiency. The 1394-DIM acts as an interface (replacing axis modules) between the 1394 GMC/GMC Turbo and external axis drives, enabling control of up to four physical axes. It also incorporates an IMC S Class motion controller, functionally equivalent to the IMC S Class Compact, and provides connections for motor feedback, auxiliary encoders, remote I/O, AxisLink, DH-485, RS-232, and RS-422 serial communications.
Is Your Device Showing These Signs?
The Allen Bradley 1394-SJT22-T-RL commonly experiences resolver feedback issues, leading to erratic motor control and drive faults. Technicians address these problems by inspecting resolver wiring for continuity and proper shielding to mitigate electrical noise. We repair damaged resolver components and recalibrate the drive parameters to ensure accurate position feedback. Power supply failures are also prevalent, requiring replacement of capacitors and rectifiers to restore stable voltage levels. Overcurrent faults are resolved through IGBT testing and replacement, preventing further damage to the servo drive.
