Hello jeet; Here is the link to the posted thread: vector control - basics If you use the search box at the right of the page (with a search term such as "Vector control") you can find many more threads dealing with similar issues. Hope this helps, Daniel Chartier |

Hi all; You can also find valuable information from one of the Sinamics product Function Manual ex: G120 https://www.automation.siemens.com/doconweb/pdf/SINAMICS_1008_E/G120_FH.pdf?HTTPS=REDIR&p=1 after page 106lots of info about V/f &Vector Control Regards |

In addition to above discussion, you can find nice detail in this Manual Vector control - should be used where high torque and precise speed control iss required where as V/F control can be used where not high torque at low speed is required Here is what MM440 OPI says The V/f characteristic represents the simplest control technique. In this case the stator voltage of the induction motor or synchronous motor is controlled proportionally to the stator frequency. This technique has proven itself for a wide range of "basic" applications, such as Pumps, fans Belt drives and similar processesWhen compared to V/f control, Vector control has the following advantages: Stable during load and setpoint changes Short rise times for setpoint changes (→ better control performance) Short rise times for load changes (→ better noise/disturbance characteristics) Accelerating and braking are possible with a max. adjustable torque The motor and driven machine are protected using the adjustable torque limit,both when motoring and regenerating The drive and braking torque are controlled independently of the speed Full holding torque is possible at 0 speed |
