Unit Description / Notes
 Used in applications with hydraulic pumps.
99 to 60
 Set the rated voltage (%Un), which will be applied to the motor
[ 100=Inactive ]
instantaneously when the Soft-Starter SSW-06 receives the ramp
deceleration command.
 For more details about programming and use, refer to Pump Control
at P202.
 Used in hydraulic pump applications.
1 to 299
 Enables and sets the time of the voltage decrement ramp.
[ 0=Inactive ]
 For more details about programming and use, refer to Pump Control.
1s
 It can be used as Voltage Ramp control, Pump Control, Current Limit
and Current Ramp.
 Used in hydraulic pump applications.
30 to 55
 Sets the rated voltage (%Un), which will be applied to the motor at
[ 30 ]
- the end of the deceleration ramp.
 For more details about the programming and use, refer to Pump
Control.
 Defines the current limit during the motor start as a percentage of
150 to 500
[ 300% ]
the rated 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 immediately.
 For more information about selection of the Current Limit control,
refer to P202.
NOTE!
To enable this function, you must set a deceleration ramp time.
NOTE!
This function is used to lengthen the normal deceleration time of
a load and not to force a shorter time than that imposed by the
load.
