Introduction

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.

The motor itself feels heavy and well-constructed, with “phoenix” style plug-and-play connectors for power, control, and communication signals.

The power connector has screw terminals to prevent it from coming loose during installation or use.

The mechanical construction of the JMC IHSV57 also feels sturdy and professional.

How to connect JMC IHSV57 180W servo

To connect the JMC IHSV57 servo motor, you can use the connection diagram provided by the manufacturer.

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.

Should I get a servo motor or stepper motor for my DIY cnc

This is not an easy question. There are many pro and cons when making this choice. In this article we talk about this subject in detail.

How to fix JMC servo control connection issues

Initially I had some serious problems getting connected to the JMC IHSV57 servo motor through the JMC servo controller software. When I purchased a premium RS232 UGREEN cable it fixed my issue.

What is a Stepper Motor?

A stepper motor is an electric motor that converts electrical pulses into discrete mechanical movements. The motor’s position can then be controlled very precisely, making it ideal for use in applications where accuracy is critical. Stepper motors are widely used in a variety of industries, including semiconductor manufacturing, automotive assembly, and medical equipment.

What is a Servo Motor?

A servo motor is a type of motor that is used to control the movement of objects. It is typically used in applications where precise control is required, such as in robotics or CNC machines. Servo motors are available in a variety of sizes and power levels to suit different applications.

Pros and Cons of Stepper Motors

There are many factors to consider when choosing which type of motor to use for your CNC router. Here, we will explore the pros and cons of stepper motors to help you make the best decision for your needs.

Pros:

– Stepper motors are more precise than servo motors, making them ideal for projects that require high accuracy.

– They are also more affordable than servo motors, making them a good option if you are working with a tight budget.

– Stepper motors are easier to control than servo motors, so they may be a better choice if you are new to CNC routers.

Cons:

– Stepper motors can produce vibrations, which can impact the quality of your finished product.

– They also tend to generate more heat than servo motors, so they may not be the best choice if you are working with delicate materials or when you have for example 3D printed motor mounts.

Pros and Cons of Servo Motors

There are many factors to consider when choosing between a stepper motor and a servo motor for your CNC router. In this blog, we will explore the pros and cons of servo motors to help you make the best decision for your needs.

Servo motors are more expensive than stepper motors, but they offer several advantages. Servo motors are more precise in dynamic applications and have better torque control. They also can start and stop more quickly than stepper motors. Allowing you to have very high acceleration values.

However, servo motors require more complex controllers and are more sensitive to vibrations. Due to requiring a control algorithm (PI or PID) it requires you to tune each motor independently to achieve good performance during acceleration and deceleration. This aspect should not be underestimated! Especially with hobby grade servo systems.

If you are looking for a budget-friendly ready to go option, a stepper motor may be the better choice.

What option did I go for?

For my personal PrintNC CNC I made use of a servo motor. Why? Compact nature of it, this specific one had an integrated controller and quick response. So far it has worked great in my setup.

Conclusion

There is no one-size-fits-all answer to this question, as the type of motor you should use for your CNC router will depend on a number of factors. However, in general, servo motors tend to allow higher accelerations and faster response than stepper motors, making them ideal for quick response industrial situations. But this comes at a much higher entry cost and effort of setup.

If you just need a budget friendly quick to setup option, seriously consider the good old stepper motor.
