PS: Just for fun, have you seen this video: Here someone drives the VFD/spindle to its limit. It stays just below the VFD tripping. The video shows the ampères in the VFD display at the output (=spindle) side, and how their 220 V 2.5 kW spindle is driven [to draw up to 10 A current from the output of the VFD (video)](https://youtu.be/h9q6j7POgOI?t=488): The test consists of driving a 10 mm 3-flute aluminium end mill through an 6061 aluminium block with 1000 mm/min feedrate, 10 mm depth of cut and 8 mm width of cut (_for U.S. customary unit system users: A 13/32" 3-flute end mill through an 6061 aluminium block with 40 IPM, 13/32" DOC, 5/16" WOC_). Another test possibly could be to rough with a 8 mm roughing bit in _black locust_, one of the hardest woods in Northern America, 1/2" deep at 110 ipm, as [shown here](https://forum.onefinitycnc.com/t/largest-clearance-bit-the-makita-router-can-use/13687/12) (they use a [6.6 kW HSD spindle](https://www.hsdmechatronics.com/en/product-families/electrospindles-atc/) on a [Hitachi WJ200](https://www.hitachi-ies.co.jp/english/products/inv/wj200/index.htm) VFD…) By the way, on the first video where Piotr tests the [2.5 kW Jianken ATC spindle](https://www.jian-ken.com/automatic-pneumatic-tool-change-spindle-motor/jgl-100-2-5kw-24000rpm-iso25-spindle-motor.html) you can hear that the spindle is slowed down a bit on high load. Piotr uses a [Huanyang HY](http://hy-electrical.com/productlist?product_category=5&brd=1) VFD without [vector control](https://en.wikipedia.org/wiki/Vector_control_(motor)), so this slowing down is what vector control is trying to avoid. On the black locust / HSD spindle link, a [Hitachi WJ200](https://www.hitachi-ies.co.jp/english/products/inv/wj200/index.htm) (nearly identical to [Omron MX2](https://industrial.omron.co.uk/en/products/mx2)) is used that supports sensorless vector control, and you can clearly see and hear that is not slowed down despite the high load. --- _[View the full topic](https://forum.onefinitycnc.com/t/woodworker-speed-control-vfd-settings/23278)._
