Overview The VS-616G5 is a full-scale flux vector (or Adaptive Vector Cotrol, AVC ) AC drive. The VS-616G5 directly s the direct curret that results i the motor torque. The VS-616G5 itegrates four fuctios i oe drive. User-friedly built-i programmable parameters (more tha 200) make most of the system tasks as easy as 1-2-3. The VS-616G5 is the ultimate drive for a wide rage of applicatios. With its extesive features it is ideal for use as a stad-aloe drive or as part of a system ad offers smooth start up from low speeds. Iteractive digital operator The user-friedly iteractive digital operator allows : Customized programmig of AC drive based o applicatios Extesive moitorig of AC drive operatig coditios 3
Torque at zero speed VS-616G5 allows smooth operatio from 1/100 th of rated speed to high startig torque. Overcomes tough starts eve without a PG*. Whe a additioal PG is istalled, it eables full torque operatio eve at zero speed. High startig torque at low speeds without PG [Speed rage 100:1 (1000:1 with PG)] Accurate Torque Cotrol The VS-616G5 offers excellet output torque respose of 150Hz with a torque accuracy of ±5%. Olie switchig from torque to speed is possible! * PG = Pulse Geerator (speed sesor) 4
Itegrated Cotrol The VS-616G5 comes with four itegrated fuctios. Speed-sesorless V/f V/f with speed sesor Speed-sesorless vector Vector with speed sesor The fuctios ca be applied to a wide rage of applicatios startig from stad-aloe drive to multi-drive systems by a simple switchig of parameters through a digital operator.
