Jun 30, 2010 · I have always heard that for loads that require a high starting torque a VFD should be set to a sensorless vector mode as opposed to V/Hz mode. What specifically about the sensorless …

Jun 9, 2010 · Offering three modes of motor control: V/Hz, Sensorless Vector and Flux Vector, the ACS550 performs accurate speed and torque control of any standard squirrel cage motor.

Aug 27, 2008 · Looking for info: Can a inverter duty motor be controlled using sensorless vector control, or is a vector motor required? The application is low speed high torque chain conv. It will have direct …

May 21, 2019 · If your VFD is capable of it, I suggest changing to what's called "Sensorless Vector Control" or SVC instead of V/Hz. That adds the ability for the VFD to "see" what's happening in the …

Dec 12, 2014 · I have a 400hp motor that is running in sensorless vector control. After the original tuning and commissioning, the system was put into service. The process required roughly a 70% load for …

Feb 19, 2010 · Sensorless Vector = The drive will compensate for motor slip and has tighter speed control regardless of load. Sensorless vector does not have good speed/torque control at low …

Jul 29, 2016 · And I doubt you would need full Flux Vector Control with an encoder feedback to attain it, Sensorless Vector Control will likely be fine (although you don't say what this is for). The application …

Nov 26, 2022 · Probably Sensorless vector control not letting is go any slower. The 160 was not a Sensorless Vector Control (SVC) drive, it was a low cost “shaft turner” V/Hz drive. So is the PF4 by …

Mar 2, 2020 · I tried setting some parametters on controller but I cant seem to set anything. The troubleshooting manual already tells me to replace control board with this issue. would like to hear if …

Sep 16, 2012 · Drive is set for sensorless vector control, torque boost, slip correction all default (and is typically the case for our drives), static autotune was ran on the motor, distribution system is on a …
