FAQ

What information is needed for model selection?

Please provide spindle motor power, rated voltage, rated current, rated speed, encoder feedback type, machine type and braking requirement.

Can SZGH help with wiring and parameter setting?

Yes. SZGH can provide wiring guidance, parameter setting suggestions and commissioning support for CNC spindle applications.

Is a brake resistor required?

A brake resistor is recommended for fast deceleration, frequent start-stop cycles or high-inertia spindle systems. Please select the resistor according to the model table and actual load.

Can this spindle servo driver be used for CNC retrofit projects?

Yes. The S4T series is suitable for new CNC machines and retrofit projects where stable spindle speed and stronger torque response are required.
