To celebrate the launch of the completely redesigned main granitedevices.com web site, we have started an ARGON & IONI sale campaign that lasts for one week. Grab the discount coupon code from the main site front page before it’s gone!
The new site
The web site is the first complete renewal since the original site introduced 2007. All content has been written my self to guarantee maximum accuracy in details. I hope it’s more clear and informative than the old one :)
We’re proud to announce ATOMI, the revolutionary multi axis drive for CNC applications. It is a closed loop stepper drive that essentially turns stepping motors into servo motors. ATOMI gives the benefits of both worlds: reliability of servos and high torque of steppers.
ATOMI age is coming
ATOMI will be launched in the Indiegogo on Q2/2016. Stay tuned and grab the early bird specials!
Ps. it is largely based on IONI technology. IONI Pro will get all the same features than ATOMI through firmware upgrades.
To celebrate the new year 2016, we have released a new IONI firmware version 1.4.0. It includes rewritten torque controller that uses 32 bit floating point precision arithmetics instead of integer arithmetics. As IONI has hardware FPU, it yielded faster code execution time as well. This makes more room for the new upcoming features.
IONI Pro HC model maximum output current in AC/BLDC/Stepper modes increased to 25A (was 23A)
Re-implemented torque controller using 32 bit floating point arithmetics instead of integer arithmetics (at least theoretical precision improvement)
DC motor mode no longer requires parallel connection of drive output phases if current is at most 50% of drive’s maximum output current capability (sensitivity of overcurrent fault with Fault ID 440219 is greatly reduced).
Changed limit switch polarity: earlier limit switches needed to be normally open (NO), while drive specifications say that they are normally closed type (NC). Now limit switchers are NC (switch conducting -> motion allowed, switch open -> motion stops).
Fix an issue where AC/BLDC motor initialization could become incorrectly phased when Hall sensors are enabled
Address an issue where torque was 5% lower than setpoint with TBW parameter value of 4700 Hz
We have released new firmware files for Argon and Ioni today. Also Granity has been updated.
Argon V2.0.0 beta 4
All reported bugs have been addressed. Beta 4 is a release candidate and it will become official 2.0 if no further problems are found. Once tested, please send feedback about it (email or comment here, also please tell which control mode you are using: torque, velocity or position). Or give vote on the poll on the right sidebar. Get the firmware from here.
This update includes lots of changes since the last release. For full change log and downloads, see this wiki page. Feedback is very welcome.
The latest Granity includes support for the Ioni V1.3.0 as well as some improvements. Starting from this release, it includes also Linux version!
Thousands thanks for contributing premium name suggestions! After a lot of consideration we chose to go with IONI Pro HC ending after drive model because:
HC extension indicates about something additional to original model. We didn’t want to remove “Pro” from the name to avoid confusion.
Short and simple
Works also with non-pro version (IONI HC)
Logical and extensible, maybe we add IONI Pro HV (high voltage) someday
Oddly, Pro HC ending never crossed my mind, I was just thinking HC Pro which I didn’t like that much. Pro HC was suggested by Thomas in Facebook comments. Congratulations for your very first serial numbered IONI Pro HC drive!
We’ll keep the other names in reserve for possible future use. If your contribution is picked later, you will be rewarded for sure.
Tomorrow (Friday 9 Oct) is the last day the new web shop launch campaign is running. So act now to avoid missing it! Also, SimpleMotion V2 USB adapter (SMV2USB) is now back in stock in large quantities.
GD at ELKOM exhibition
On the other news, we have got a very positive visit to ELKOM exhibition at Helsinki during 6-8 Oct. To celebrate the fair, we are giving extra 5% off from Argon drives before 9 Oct with coupon code “ELKOM”.
We will be soon receiving a pilot batch of the new enhanced IONI model with the best-in-class power MOSFET transistors to increase the current capacity. Other change is an increase of voltage sense range, which will allow few volts more usable voltage range.
We’re thinking the naming of it. I thinki IONI HC Pro would sound clumsy. Perhaps something like IONI XPro would suit better. What do you think? Or perhaps give an idea in comments. If your suggestion is chosen, you will win a free high current IONI with the very first serial number!
Update: we will arrange a poll within our staff to pick the winner! All entries before Monday 12 October will make it to the voting. Keep the ideas coming!
Dear Granite Devices customers, we have temporarily ran out of Argon servo drives recently due to increased popularity (great!) and unfavorable variations in the production time (not so cool) occurring at the same time. A longer than usual production lead time is caused by limited stock availability of certain third party electric components. We have to wait until beginning of August to receive new 300 pcs delivery of Argon drives.
However, we have kept back a small number of Argons for emergency needs. If you need one very urgently and absolutely can’t wait for the delayed delivery, contact us by email at sales (at) granitedevices.fi. Those who have ordered the drive before the outage and are waiting over the unexpected delay will receive a 100 euro discount/refund per drive as compensation. Discounted orders are the ones made between the dates 13.6 and 25.6.
To reduce greatly the chance of outages in the future, we are starting to stock the most critical components in order reduce lead time variations.
Meanwhile all IONI series products are in stock and shipping normally. If you wish to change your order from ARGON to IONI, or make other changes to your order, please drop us email.
