FANUC, Mitsubishi, Brother and Siemens
Common CNC systems can be supported after the exact control model, communication interface and machine configuration are confirmed.
CSD700 Integrated 4th/5th Axis Servo Controller Drive
CSD700 is Yidai's second-generation external-axis control solution for upgrading a three-axis CNC machine with an indexed fourth or fifth axis. It combines the external-axis controller and servo drive in one compact unit, helping reduce cabinet space, separate components and field wiring.
Integrated Rotary Table Servo Controller Drive
For CNC rotary table manufacturers, CSD700 can be matched with a 400 W to 1 kW servo motor according to table ratio, torque, speed, inertia, encoder, brake method and target CNC interface.
Unlike the first-generation YD-1 standalone controller architecture, CSD700 integrates the axis-control function and servo-drive function in a single device. A complete retrofit solution can be configured with the CSD700, a matched servo motor, CNC rotary table, brake/clamp circuit and machine-interface wiring.
- Supports matched servo power ranges from 400 W to 1 kW.
- Can be configured for an external indexed 4th axis or 5th axis.
- Designed for 3+1 and 3+2 positioning applications on existing three-axis machining centers.
- Suitable for multi-face machining, bolt circles, radial holes, side features and other fixed-angle operations.
- Compact integrated construction simplifies installation and troubleshooting.
Compatible CNC systems
CSD700 retrofit projects can be evaluated for FANUC, Mitsubishi, Brother and Siemens CNC machines. Final compatibility depends on the exact CNC model, software version, available communication resources, machine-builder PLC logic and electrical wiring.
| CNC system | Typical manual operation | Items to confirm |
|---|---|---|
| FANUC | The original machine handwheel can be retained on compatible configurations. | Full CNC model, software version, macro/variable access, communication ports and machine PLC. |
| Mitsubishi | The original machine handwheel can be retained on compatible configurations. | Controller series, Ethernet/serial resources, variable addresses, axis-select and multiplier signals. |
| Brother | An additional electronic handwheel is required for manual movement of the external axis. | Communication interface, program call method, handwheel installation and in-position signal. |
| Siemens | An additional electronic handwheel is required for manual movement of the external axis. | System version, interface resources, program logic, safety interlocks and handwheel wiring. |
How the retrofit works
- The CNC program moves the cutting tool to a safe position.
- The machine sends a positioning command or target angle to the external-axis system.
- The rotary table releases its clamp and moves to the requested angle.
- CSD700 confirms positioning, and the rotary table is clamped again.
- An in-position/ready signal is returned to the CNC machine.
- The original X, Y and Z axes continue the machining cycle.
The communication method may use I/O, serial communication or Ethernet depending on the CNC model and project requirements. The final solution must include servo alarm, origin, limit, positioning, clamp and machining-permission interlocks.
Important application boundary
CSD700 is intended for indexed positioning. If the rotary axis must move continuously and simultaneously with X, Y and Z during cutting, the project should be evaluated as a native interpolated-axis upgrade or a dedicated multi-axis machine application.
What to provide for a compatibility evaluation
- Machine brand, model and nameplate photo.
- Complete CNC model and software/version screen.
- Machine control panel and handwheel photos.
- Electrical cabinet and available Ethernet, serial and I/O interface photos.
- Existing rotary table, servo motor and drive nameplates, if already installed.
- Workpiece drawing, required indexing angles and machining sequence.
- Required fourth-axis or fifth-axis configuration and rotary-table size.
Supply scope
Depending on the project, Yidai can provide the integrated CSD700 controller/servo drive, matched servo motor, rotary table, required control wiring and retrofit compatibility support. Rotary table manufacturers can review the OEM servo motor, drive and controller package. The final configuration is quoted after the machine and workpiece information has been reviewed.
Frequently asked questions
What servo power does CSD700 support?
CSD700 supports matched servo systems from 400 W to 1 kW. Final motor selection depends on rotary-table transmission, workpiece and fixture load, required torque, speed, inertia, braking and duty cycle.
Can every FANUC or Mitsubishi machine use the original handwheel?
No. The original handwheel can be retained only after the exact CNC model, version, communication resources, variable permissions and machine-builder wiring have been confirmed.
Do Brother and Siemens machines need manual operation during automatic machining?
No. The additional handwheel is used for setup, homing and manual movement. During automatic machining, the CNC program calls the target angle and waits for the rotary table to reach position.
Is the servo motor included?
A matched servo motor can be supplied as part of the complete solution. Motor power and rotary-table configuration are selected according to the required torque, speed, load and machining conditions.
