Hi,
I control a servo drive using 7344 board (PID controled, 131072 lines
per revolution encoder, torque controled by DAQ ouput of the board).
I 'd like to achieve very low speed change in a long time. Therefore, I
ask speed profile whith acceleration as low as 0.01 rounds/s², with
speeds as high as 1500 rounds/s.
When I do this, i notice that after a certain time where the drive
accelerate, a limit speed is reached. This limit speed is proportionnal
to the acceleration asked (or the time of acceleration). If i reorder a
move on this board, this limit speed is never reached. To get an idea,
limit speed is aroung 500 rounds/s for a 1 rounds/s² acceleration (and
50 rounds/s for a 0.1 rounds/s² acceleration)
Does anybody as an idea on the origin of this problem?
Thanks in advance,
Matthieu.
