Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with
the Manufacturer Instructions, National Electrical Code and any additional
local codes.

Software Functions
•
Modified space vector modulation (SVM) technique to reduce the power stage losses
•
Field oriented current controller (update time 62.5 µs)
•
Feedback evaluation and speed controller (update time 62.5 µs)
•
Spline interpolation and position controller (update time 62.5 µs)
•
Full synchronisation up to the output stage to the control frequency with cycle times of
250 µs, 500 µs and 1 ms to 8 ms
•
The servo amplifier has a volatile data storage medium. After power-up, the parameters
are loaded into the servo amplifier via the host
•
Starting with FW version 1.82, the electrical rotary field frequency is limited to 599 Hz.
The error bit 18 is set when the frequency is above 599 Hz for more than one second.
The amplifier then changes to error status. The cause could be a high rotation speed
with motors that have a high number of poles.
