Rotor locked [422]
With the rotor locked function enabled, the AC drive will
protect the motor and application when this is stalled whilst
increasing the motor speed from standstill. This protection
will coast the motor to stop and indicate a fault when the
Torque Limit has been active at very low speed for more
than 5 seconds.
Communication information
Motor lost [423]
With the motor lost function enabled, the AC drive is able
to detect a fault in the motor circuit: motor, motor cable,
thermal relay or output filter. Motor lost will cause a trip,
and the motor will coast to standstill, when a missing motor
phase is detected during a period of 500 ms. The detection
time during DC-start is 50 ms and during Fast-start 10 ms. .
Communication information
Overvolt control [424]
Used to switch off the overvoltage control function when
only braking by brake chopper and resistor is required. The
overvoltage control function, limits the braking torque so
that the DC link voltage level is controlled at a high, but
safe, level. This is achieved by limiting the actual
deceleration rate during stopping. In case of a defect at the
brake chopper or the brake resistor the AC drive will trip for
“Overvoltage” to avoid a fall of the load e.g. in crane
applications.
