🎛️ PWM / Modbus Cable for Spindle Systems

Precision Connectivity for Reliable Spindle Control

Whether you're setting up PWM or Modbus control for your VFD, this is the high-quality cable you need to complete your spindle installation with confidence.

We've done the hard work—sourcing top-tier components and testing each configuration across the most popular CNC machines—to deliver a plug-and-play cable that’s tailored to your system.

🔌 What’s Included

12 ft Shielded Control Cable
- Terminated with high-quality connectors for both your CNC controller and VFD
- Designed specifically for low-noise, high-signal integrity
- These are a physically shielded cable. For optimal EMI performance, the shield must be grounded properly at the controller or VFD end.

Fast service, great support, nice product

I have older shapeoko 3, doesn’t have bit runner connection. So this cable is useless to be. Product quality is outstanding !!

Pwm modbus control cable and spindle kit

Work just like they said it would. Direction were great and assembly was no issue. Works like a champ. Thank you

Master class in service

I recently had an issue where the wrong cable was sent with my order but Pwn CNC’s customer service turned what could have been a frustration into a real positive experience. Their team responded quickly, resolved the problem without fuss, and made sure I was back up and running in no time.
What really stands out is that their customer service matches the quality and innovation of their products. It’s one thing to see clever engineering and forward thinking design in the workshop, but it’s another to have that same level of care and attention reflected in how they treat their customers. That combination is a delight to see, and it makes me even more confident in continuing to invest in their ecosystem.
Highly recommended for both the products and the people behind them.
