Software functions
•
Modified space vector modulation (SVM) technology to reduce power
output loss.
•
Field oriented current regulator (update every 62.5 µs)
•
Feedback evaluation and speed controller (update every 62.5µs)
•
Spline interpolation and position controller (update every 62.5µs)
•
Full synchronization up to the output stage to the control frequency
with cycle times of 250µs, 500µs and 1ms to 8 ms
•
The servo amplifier has a volatile data storage medium. After power-
up, the parameters are loaded to the servo amplifier through the host.
•
Since FW version 1.82 the electrical rotary field frequency is limited to
599 Hz. Error bit 18 is set, if the frequency is higher than 599 Hz for
longer than one second. The drive then goes to error status. Reason
might be a too high rotational speed of the motors with a high pole
number.
