Siyuer 998T CNC Controller with Integrated PLC an | RFQ Sourcing Details

The Siyuer 998T is a CNC controller with integrated PLC and HMI functions for configurable turning-machine control. Its axis configuration covers 2–6 axes, with X, Z, Y, A, B, and C axes identified in the supplied specification.

Axis outputs support pulse-and-direction and orthogonal-pulse signals for connection to suitable AC servo or stepper drive units.

Motion functions include straight-line and circular interpolation, a minimum command unit of 0.001 mm, a stated positioning command range of -9999.999 to 9999.999 mm, and a 1 ms interpolation cycle. Rapid travel is specified at up to 30,000 mm/min, while cutting feed is specified at up to 15,000 mm/min or 500 mm/rev.

Real-time rapid and feed-rate adjustment, manual feed settings, three handwheel increments, automatic chamfering, and separate acceleration/deceleration profiles for rapid movement and cutting feed are also listed.

For turning operations, the controller supports single- and multi-start external metric straight threads, tapered threads, face threads, and variable-pitch threads.

Its compensation functions include per-axis backlash compensation, pitch-error compensation with 512 points, 32 sets of X- and Z-axis tool-length compensation, and tool-tip-radius compensation using method C. Up to 32 cutting positions are identified.

Programming features include G-code operation, G65 macros, arithmetic and logic operations, conditional jumps, nested subroutines, and a stated capacity of 100 MB and up to 10,000 programs.

The operator interface supports Chinese and English display modes, processing-trajectory graphics, alarm logging, a real-time clock, soft keys, and full-screen program editing.

The source information references both 8-inch and 10.4-inch LCD options, while the basic configuration also lists an 8.4-inch screen;buyers should therefore confirm the exact display supplied with the selected configuration.

Spindle control includes two 0–10 V analog-output channels and support for spindle-speed or cutting-line-speed commands. The specification also identifies four spindle gears and frequency-conversion gears.

Electrical details list 220 V power and 52/26 I/O, but the exact meaning and allocation of the I/O count should be confirmed before panel design.

Procurement questions to confirm: Verify the required axis count, enabled PLC functions, axis and spindle interfaces, encoder type and line count, display size, I/O map, connector and cable package, drive and motor compatibility, installed software options, and supported machine configuration.

Also confirm the exact enclosure and panel materials, electrical input requirements, included accessories, customization scope, documentation language, package contents, acceptance-test procedure, and the applicable warranty terms for the quoted configuration.
