Deceleration Control shall be built in and be selectable with the following adjustments, all of which shall be completely independent of any acceleration setting. 

Ramp Type for stop: For the stop ramp, it shall be possible to select between a voltage ramp and torque control. 

Ramp Time for Stop: The deceleration time shall adjustable from 0-30 seconds to allow controlled deceleration and soft stop of the motor. 

End Voltage Level: End voltage level shall be adjustable from 20-60% of line voltage. The end voltage shall be set simultaneously as the initial voltage (at start). 

Torque Control:  Torque control feature shall be based on closed-loop principle with self-adjusting output to thyristors. The self-adjustment in the closed-loop shall be in relation to an actual and ideal load characteristic, where the ideal torque is set up using the soft starter parameters. The objective of the torque control feature shall be to obtain smoothest possible stop-ramp for pumps where output torque curve closely follows the load curve in order to prevent pressure surges and water hammering. 

## (6) Motor and Load Protection 

Motor and Load Protection shall be integrated with the soft starter and all the protection functions shall under no circumstances be disconnected or disabled when the integrated by-pass contactors are used. 

All the different protection functions shall be selectable individually and all be switched off as default except for the Motor Overload Protection. In order to protect both the load and motor the Soft starter shall be provided with the following functions: 

Motor Overload Protection: This protection shall be possible to turn on and off. When active, (On) it shall be possible to select between some predefined standard overload trip curves. The trip curves shall be selectable between the following tripping classes - Class 10A, 10, 20 and 30. The overload protection shall be based on a thermal register retained in memory until the motor is completely cooled down (no risk of re-starting the motor). 

Motor Underload Protection: This protection shall be possible to turn on and off. When active (On) it shall be possible to set between 0,2 - 1,0 times the set rated current value. 

Locked Rotor Protection: This Locked Rotor Protection shall be possible to turn on and off. When active (On) it shall be possible to set between 0,5 – 7 times the set Ie value. 

Manual or Automatic Reset:  For the three different protections above it shall in be possible to select between manual reset and automatic reset in unattended remote applications. The factory default shall be manual reset. 

Thermal Memory: The over load protection shall not lose track on the motor temperature if the control supply voltage is lost or shut down, or the motor is stopped. Upon reapplication of power within two hours, the microprocessor shall be updated as to the motor temperature and adjusted for real time cooling while the power was off. 

Thermal Capacity Reset Level : If the Motor Overload Protection is tripping, the softstarter shall not allow a restart (reset) until the motor has cooled down to 60% of its total thermal capacity. 

Phase Reversal: The soft starter shall be totally insensitive for Phase Reversal and shall be able to start in all various combination of incoming phase orders. 

## (7) Softstarter Protection 

Soft starter protection shall be provided to maintain reliability of both the driven equipment and the electrical components, with the following features:
