This IC both isolates the microcontroller from the high voltage MOSFET and switches the MOSFET with a higher voltage and current than the microcontroller could. Model Year. 1. I wasn’t able to get the rotation direction to reverse. A wide variety of mini lathe speed controller options are available to you, such as totally enclosed. With the motor speed turned down too low, the cutter moves very slowly across the blank. Wood. Based on the data sheet, the pinout didn’t match exactly, but it was close. I also noticed that the input from the microcontroller went to two pins each. Apparently most of the newer 7x12 mini lathes are now coming with a KBIC-240D speed controller stock. Astonishingly, I’ve actually found some technical information on it, and there even appears to be a few individuals out there that repair them. if you want a more in-depth answer. 3.0 (1) 2 Orders. Terms of Use If my choice was the stock controller or a KBIC/KBLC I would go with the KBIC/KBLC, even though they're SCR simply for the significantly greater performance and adjustability they offer. Change gears: 21, 30, 35, 40 (2), 45, 50, 55, 57, 60, and 65 Change ), You are commenting using your Twitter account. The output from the comparator will either turn on the green “normal” LED and send Vcc to the gate driver IC, or will turn on the red “OP” LED and cut off Vcc to the gate drive IC. My guess for why they have both a 12 V tap on the transformer and a 12 V voltage regulator is so that they could use a smaller voltage regulator to feed only the logic ICs instead of the higher current relay coils. Use with motor controller boards. I knew it would be the perfect addition for my home shop if I could get it working. Click here to see if this fits your lathe Kit | Affiliate, Product Listing Policy The power board supplies 5 VDC and ground to the logic board. Limited Time Sale Easy Return. This high quality high accuracy precision lathe is designed for model engineers’ use in the home workshop, repair workshop or schools.

Kit includes: nuts, bolts, wiring, control box, motor, motor pulley, assembly templates and assembly instructions for Turncrafter, Jet and Delta lathes. However, when you pressed the forward button on mine, the lathe would do nothing for a few seconds and then beep loudly and flash ‘A001″ on the display. Taking a closer look at the logic board, I found a 8 pin DIP IC with its part number marking intentionally removed, which made investigating this IC challenging. John Mattis All the other components between the output of the gate driver and the MOSFET gate seemed fine, but there was never any voltage on the gate pin when the controller was attempting to start up the motor. Peter replace the speed pot and upgraded the board to provide more low-speed torque. Maximum Current: 20A. Bolton CQ6118 7x12 lathe.
