Vfd options for the US

Is anyone else using a VFD that are not from pwncnc or Huanyang? And what are your thoughts on the pros and cons?

I am using a vfd (Mollom VFD 220V 2.2KW 3HP 9.6A… https://www.amazon.com/dp/B0BM5RRX9M?ref=ppx_pop_mob_ap_share) on another piece of equipment. Based on it not being a certified ul device (ie:affordable) I only leave power to it when I am using it and in the shop.

Hey Sylthecru,

that’s a good price:

Note: Hitachi WJ200 is practically identical to Omron MX2 (PDF Manual). This means all settings for Omron MX2 you find in the forum also apply to Hitachi WJ200 and vice-versa. The only difference I could find is that the Hitachi offers 0–400 Hz while the Omron offers 0–580 Hz.

PS: The Hitachi WJ-C1(-022SFE) supersedes the WJ-200(-022SF). It is downward-compatible to WJ200.

Product Update: Hitachi WJ200 Series

Posted by Theresa Hoffman on Feb 14th 2024

Attention Hitachi WJ200 Series users!

Hitachi has announced the phase out of WJ200 series. But don’t worry, they’ve already introduced the WJ-C1 as its replacement.

We’ve taken a closer look at the update, and here’s what you need to know.

What’s the same?

We get it: seeing “discontinued” on equipment you rely on can be unsettling and confusing.

Deciding on alternatives or replacements is a daunting task, often leaving you with more questions than answers.

The good news is, the Hitachi WJ-C1 series is designed for an easy transition!

It’s identical mounting footprint to the WJ200 makes it a straightforward replacement.

And, by maintaining the same communication protocols, it allows for integration with an existing control system.


New Look

Say goodbye to the up and down arrows!

Hitachi developed the new WJ-C1 Series with a JOG dial as a replacement for those traditional controls.

This innovative dial allows for precise movement in small increments, which is perfect for tasks like calibration and fine-tuning.

That’s not all! By running your motor at a low speed, you can use the JOG function to diagnose potential problems before they arise.


Certifications and Functionality

In addition to CE, UL and c-UL certifications, the new WJ-C1 is also EU-RoHS2 compliant.

Restricting the use of hazardous materials, Hitachi WJ-C1 aligns with in-demand, eco-friendly products.

Now, the question you’ve been waiting for: will it function the same?

As mentioned before, the WJ200 and WJ-C1 share basic functionalities.

The WJ200 Series has a built-in PLC functionality and caters to customization, while WJ-C1 Series focuses on user-friendliness with simplified features like RS485 communication, PID control and an intuitive LCD screen.

Price:€ 344,00 The industrial inverters WJ-C1 series are easily configurable, very efficient and fully compatible to the older series. It offers excellent performance and flexibility.
The WJ-C1 inverters can be used to drive both induction motors (IM) and permanent magnetic motors (PM). Ideally suited for applications such as textile machines, materials handling, roller shutters, pump and fans and much more.

The WC-J1, is this drive compatible with the Masso controller?

Hey hyspead,

yes of course. Masso does not support controlling VFDs by Modbus like the Buildbotics Controller does, but it controls them by the 10 V analog voltage for SPEED / digital input terminal for RUN/REV/STOP. This is supported by practically all VFDs. See Spindle VFD examples – Masso Documentation and Hitachi WJ200/Omron MX2 wiring to Masso GX12 6-pin connector.
