Vector control

Differences with respect to vector V/f control

Compared with vector V/f control, vector control offers the following benefits:

● Stability for load and setpoint changes

● Short rise times for setpoint changes (→ better control behavior)

● Short settling times for load changes (→ better response to disturbances)

● Acceleration and braking are possible with maximum settable torque

● Motor protection due to variable torque limitation in motor and regenerative mode

● Drive and braking torque controlled independently of the speed

● Maximum breakaway torque possible at speed 0
