When Soft-Starter SSW-07 is programmed to Voltage Ramp control,
this is the voltage increment ramp time.
When Soft-Starter SSW-07 is programmed to Current Limit control,
this time is used as the maximum starting time, working as a
protection against blocked rotors.

NOTE!
The programmed acceleration time is not the exact motor
acceleration time, but the time of the voltage ramp or the maximum
starting time. The motor acceleration time depends on the motor
characteristics and the load.
Please consider that in cases where the relation of the SSW-07
current and the motor nominal current is 1.00, the maximum time
that the SSW-07 can work with 3 x In is 30 seconds.
Enables and sets the time of voltage decrease.
This setting should be used only for the deceleration of pumps to
reduce the water hammer. This setting must be made to achieve
the best pump performance.
NOTE!
This function is used to lengthen the normal deceleration time of a
load and not to force a lower time than that imposed by the load itself.
