End Deceleration [ 30 ]
Voltage 1% Un of the Motor

Used in hydraulic pump applications.

Sets the nominal voltage (%Un), which will be applied to the motor
at the end of the deceleration ramp.

For more details about the programming and use, refer to Pump
Control at P202.

Automatic Detection [ 0=By Time ]
of the Acceleration 1
End with Voltage
Ramp

It allows applying full voltage to the motor as soon as it reaches its
nominal speed, before the end of the time programmed in P102, for
voltage ramp starting.

The end of the acceleration ramp is detected when P007 reaches
95% of the line voltage at P004.

This function is used to avoid that the motor maintain operated at
the nominal speed with voltage below the nominal, thus avoiding
possible SCR burning due to the synchronism loose in that con-
dition.

Current Limit [ 300 ]
1% In of the Motor

Defines the current limit during the motor start as a percentage of
the nominal motor current set at P401.

When the current limit is reached during the motor start, the
Soft-Starter SSW-06 will maintain the current at this limit until the
motor reaches the end of the start.

When the current limit is not reached, the motor will start immedia-
tely.

For more information about selection of the Current Limit control,
refer to P202.
