Ground fault protection
The drive is equipped with an internal software that protect the motor and the drive against input and
output unbalanced currents. The response threshold can be set from 0% to 30% of the rated current.
For further information, see Programming and Software Manual .
This function is not intended to protect people against direct or indirect contacts or against fire, so an
external protection must be provided to ensure that a substantial ground fault current is promptly
interrupted. The SD750FR drives are suitable to operate with RCD components Type B, if it is required.
The EMC / EMC filters and motor cable lengths increase the earth leakage currents, so the protection
range is set according to the installation conditions. For additional information, contact Power
Electronics.
Motor thermal protection
The drive includes a motor thermal protection based on the motor performance parameters which
mathematically calculates the remaining heating capacity in the motor. When this reservoir is reduced
below the limits, this is, the motor temperature approaches the maximum, the drive automatically stops
the motor. For further information consult the Software and Programming Manual .
The drive includes as standard a PTC connection that permits monitor the motor temperature. Once
connected and configured, the drive could either stop the motor or generate a warning signal.
