DC Magnetizing

When DC Magnetizing is activated, the drive automatically magnetizes the motor
before starting. This feature guarantees the highest possible breakaway torque, up to
180% of the motor nominal torque. By adjusting the paramagnetism time, it is
possible to synchronize the motor start. The Automatic Start feature and DC
Magnetizing cannot be activated at the same time.

Acceleration and deceleration ramps

Two user-selectable acceleration and
deceleration ramps are available. It is possible to
adjust the acceleration/deceleration times and
the ramp shape. Switching between the two
ramps can be controlled via a digital input or
fieldbus.
The available ramp shape alternatives are
Linear and S-curve.
Linear: Suitable for drives requiring steady or
slow acceleration/deceleration.
S-curve: Ideal for conveyors carrying fragile loads, or other applications where a
smooth transition is required when changing the speed.
