Introduction

Are you looking for a low-cost servo motor for your DIY CNC machine? The JMC IHSV57 180W DC servo motor may be the perfect choice for you. This servo motor has gained popularity in the DIY CNC field in recent years for its quick rapids and potential for increased accuracy.

Unpacking the JMC IHSV57

When you unpack the JMC IHSV57, you’ll find that it is well-packaged in a sturdy box with ample foam padding.

You can find the connection diagram here *I do not use the ELS 4 controller but GRBRLHAL2k*

For a neater and easier to manage connection, you can use shielded flexible ethernet cable to connect the servo/stepper signals to your CNC controller. This helps to reduce EMI and EMC issues.

This made the connection very easy and clean. The twisted pairs and double shielding of the CAT5 ethernet cable helps enormously against EMI and EMC issues. I really recommend using it. You can find the 8 wire to ethernet adapter from Aliexpress here

JMC servo motor tuning

Tuning the JMC IHSV57 servo motor can be a bit more challenging than with more expensive controllers, but there are resources available to help you. Videos such as those listed in this article can provide helpful guidance for initial autotuning and further understanding of the tuning process.

Where you would get 80-90% there while using “proper” autotuning algorithm from a more professional but also much more expensive servo controller, with the JMC servo control software it is a bit more work.

Normally I would use resources such as the National Instruments – Understanding servo tuning guidelines.

But for the JMC servo tuning I found the following resources the best to get started on tuning your IHSV57 servo:

This first video gets you going with the initial autotuning.

The second video got gave me a lot extra background information and allowed me to tune my IHSV57 servo motors well.
