Unit Description / Notes
 When the Soft-Starter SSW-06 has been programmed to Voltage
1 to 999
[ 20 ]
Ramp Control or Pump Control, this will be the ramp time of the
1s
voltage increment as shown in Figure 6.2.
 When the Soft-Starter SSW-06 has been programmed to Current
Limit control, Torque Control or Current Ramp, this time acts as
maximum starting time, as a protection against locked rotor.

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION
NOTE!
When another control type is selected, not the Voltage Ramp
or Pump Control, the initial voltage will be attenuated due to the
limit imposed by the current.

NOTE!
The time set at P102 is not the exact motor acceleration time,
but the voltage ramp time or the maximum start time. The motor
acceleration time will depend on the motor and the load
characteristics.
