DAT series AC servo driver including DAT2030C, DAT2050C and DAT2075C are developed with universal serial bus, absolute encoder interface, it is a brand new product which realizes real-time communication between the AC servo drivers and the CNC controller, and the accuracy of speed and position is improved remarkably. DAT series AC servo drivers are the best solution for CNC machines and other automation facilities.
With GSKLink universal serial bus, realizes remote servo debugging and real-time monitoring.
Use absolute encoder (BISS, 17bit/round, 12bit/round) as position feedback, not only improves the accuracy of speed and position, further more, CNC machines use CNC controller with GSKLink universal serial bus and DAT series AC servo drivers can be run without Zero Point Switches.
Max. frequency of position pulse is 1MHz, with 0.1um type CNC realizes 0.1um grade accuracy.
Realize speed advance control, which improves the dynamic response and reduces the following error.
Improves braking current and shorten braking time. Outer brake resistance is also acceptable to suit the high speed start and stop, and high inertia load.
Improves the power fail detecting and brake control, so the brake act faster when power fail.
