The board carries the control electronics of that unit, so the drive&#8217;s own diagnostics and its output control run through it. It is a drive board, not the lift controller: when it fails the controller is still alive, but the motor gets no drive.<\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">Q2: Is it the same as an MC1 or MC2 board?<\/strong><\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">A:<\/strong>\u00a0No. MC1 and MC2 are controller boards, and this one belongs to the inverter section. They are different parts in different places in the cabinet, and one cannot stand in for the other. If you are not sure which section your board comes from, send us a photo of the cabinet with the board in place.<\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">Q3: Does the revision matter?<\/strong><\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">A:<\/strong>\u00a0Yes. The board is listed in more than one revision, and Rev 2.0 is the one most distributors carry. A different revision may not behave like the board you are taking out, even where the marking looks the same. Read the revision printed next to the marking and tell us both before ordering.<\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">Q4: Which TKE inverters use this board?<\/strong><\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">A:<\/strong>\u00a0The public listings for MNCU-8C do not name the drive families, so we will not guess at them. What identifies it is the marking on the board, the revision, and the drive label in the cabinet. Send us those photos and we will confirm the fit for your installation.<\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">Q5: The drive trips and the lift stops. How do I know the board is at fault?<\/strong><\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">A:<\/strong>\u00a0Note the fault code the drive displays first, because it points at the section that failed. Check the supply and the motor connections before the board: a loose power terminal or a motor insulation fault produces the same stop. If the supply and the motor are sound and the code keeps returning, the main board is the next suspect.<\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">Q6: What should I send before ordering?<\/strong><\/p>\n<p class=\"!mt-2 !mb-2 leading-relaxed\"><strong class=\"font-semibold text-zinc-900 dark:text-zinc-100\">A:<\/strong>\u00a0A photo of the old board, front and back, with the marking and the revision readable. A photo of the drive label, and the fault codes the drive has stored. With those three we confirm the board, the revision and the fit before dispatch.<\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"!mt-2 !mb-2 leading-relaxed\">MNCU-8C is the main board of the TKE elevator inverter, the control board of the drive unit that feeds the hoisting motor, mounted in the drive section, not in the car. Distributors also list it as PWB-PL MNCU-8C, and it is supplied in more than one revision, including Rev 2.0. A failed board takes the drive down, so the lift stops even when the controller is healthy.
