1.3.2 Functional Description
Ramp up
During ramp-up the controller will gradually increase the
voltage to the motor until it reaches full line voltage. The
motor speed will depend on the actual load on the motor
shaft. A motor with little or no load will reach full speed
before the voltage has reached its maximum value. The
actual ramp time is digitally calculated and will not be
influenced by other settings, net frequency or load
variations.
Initial torque
The initial torque is used to set the initial starting voltage.
This way it is possible to adapt the controller to an
application requiring a higher starting torque. In some
cases the application will need a high break-away torque.
Here, the initial starting torque level can be combined with
a kick start function. The kick start is a period of 200 ms
where the motor receives full voltage.
Soft stop
During ramp-down the controller will gradually reduce the
voltage to the motor thus reducing the torque and
current. As a consequence the motor speed will fade off.
The soft stop feature is advantageous to avoid liquid
hammering and cavitation on pumps, and to avoid goods
tilting on conveyors.

- Thanks to the adjustable initial torque and the unique breakaway kick start function the soft starter can be optimized for almost any application the mcd 100 soft starters are typically used on motor applications where a smooth stat and or stop is advantageous such as conveyors fans pumps compressors and high inertia loads mcd 100 soft starters are also obvious as replacement for star delta starters 2
- The digitally controlled soft starter features accurate settings and easy installation the controller has individually adjustable acceleration and deceleration times 2
- The mcd 100 soft starters are designed for soft starting and stopping of 3 phase a c motors thus reducing the inrush current and eliminating the damaging effects of high starting torque surges 2
