Hello,
In the past we used a single Altivar 71 to control 4 motors on a gantry crane. We used this in the open loop V/Hz function . A laser distance meter with PID control was used to automatically drive this crane into the correct position. Now we are using an ATV 930 drive, which only has vector control. It looks as though the ATV and laser are fighting each other to correct the AI into the drive to obtain the correct speed whenever there is a sudden load change. Is there a way to allow the ATV930 to work similar to v/Hz mode?
