Power limit
Power limitation is used to protect the input bridge and the DC intermediate circuit.
If the maximum allowed power is exceeded, the drive torque is automatically limited.
Maximum overload and continuous power limits depend on the drive hardware.
For specific values, see chapter
on page
Automatic resets
The drive can automatically reset itself after overcurrent, overvoltage, undervoltage,
external and “analog input below a minimum” faults. The Automatic resets must be
activated by the user.

Supervisions
The drive monitors whether certain user selectable variables are within the user-
defined limits. The user may set limits for speed, current etc. The supervision status
can be indicated through relay or digital output.
The supervision function outputs can be used for triggering some drive functionality
(start/stop, sleep, pump cleaning).
The supervision functions operate on a 2 ms time level.
