Safety Functions
The following safety functions bring about controlled stop of the spindle according
predefined deceleration times:
Safety stop because of converter excess temperature after delay-time of 10s
is exceeded
Safety stop by overload and time delay exceeded (default 10sec)
Safety stop will occur immediately by exceeding the maximum admissible spindle
current.

EMC (electromagnetic compatibility)
The compliance with the limit values of EMC is the responsibility of the manufacturer of the
machine or device.
This device was developed for use in industrial environments. For trouble-free operation and
to reduce emitted interference, the following should be observed during wiring of the
equipment:
The EMC of a machine or device is affected by all connected components (motor spindle,
length and type of cables, wiring, etc..). Under certain conditions the use of additional filters
can be necessary to maintain the current laws.
The earth and shield connections of all those devices used in conjunction with the frequency
converter should be as short as possible and have as large a cross-section as possible.
Control devices used with the frequency converter (PLC, CNC, IPC, ...) should be connected to
a common earth/earth terminal bar
All connections both to and from the frequency converter should be via shielded cable.
Supply cables, motor cables and control cables must be completely isolated from each other.
Where crossing cannot be avoided, cables should be laid at 90° to each other.
The control cable should be laid as far away as possible from the load cable.
