been reached, the acceleration continues with the same rate
to the value defined by parameter
If the reference increases faster than the set acceleration
rate, the motor will follow the acceleration rate.
If the reference increases slower than the set acceleration
rate, the motor frequency will follow the reference.
If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to exceed
the drive torque limits.

Note: If a short deceleration time is needed for a high inertia
application, the drive should be equipped with braking
equipment such as a brake chopper and brake resistor.
