WARNING!
When the vector control mode is in use, never open the output contactor while the
drive controls the motor. The vector control operates extremely fast, much faster
than it takes for the contactor to open its contacts. When the contactor starts
opening while the drive controls the motor, the vector control will try to maintain
the load current by immediately increasing the drive output voltage to the maximum.
This will damage, or even burn the contactor completely.
Implementing a bypass connection
If bypassing is required, employ mechanically or electrically interlocked contactors between
the motor and the drive and between the motor and the power line. Make sure with
interlocking that the contactors cannot be closed simultaneously. The installation must be
clearly marked as defined in IEC/EN 61800-5-1, subclause 6.5.3, for example, “THIS
MACHINE STARTS AUTOMATICALLY”.
WARNING!
Never connect the drive output to the electrical power network. The connection
may damage the drive.
