5 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
