CHAPTER 5 - START-UP

5.3 START-UP

This Section describes the start-up procedure when operating via the
Keypad (HMI). Three types of control will be considered:
Start-up by Voltage Ramp:
The start by voltage ramp is the most used method and its programming
and parameter setting is very easy to do. The Soft-Starter SSW-06
applies the voltage to the motor without any feedback of the voltage or
current applied to the motor
Start-up by Current Limit:
The maximum current level is maintained during the start-up and it is
set according to the application requirements. This programming is
very easy.
Start-up by Current Ramp:
The maximum current level is also limited during the start-up, however
higher or lower start-up current limits can be set.
Start-up by Pump Control:
Optimized control method, providing the required torque to start/stop
hydraulic centrifugal pumps smoothly.
Start-up by Torque Control:
The Soft-Starter SSW-06 is fitted with a torque control algorithm of high
performance and is totally flexible to meet any application requirement
during the motor start or stop and its coupled load.
The method allows a torque control with 1 setting point, a torque control
with 2 setting points and a torque control with 3 setting points.
NOTE!
Every time the content of the Parameter P202 is changed, the Soft-
Starter will execute a setting sequence routine according to the selected
control type.
For more details, refer to Parameter P202 in Chapter 6 and 7.
The following sequence is valid for Drive 1 (see item 3.3.1). The SSW-06
Soft-Starter must already be installed and the electronics, fans and
power must already be energized, according to chapter 3, with the
setting sequence of the initial Start-up complete, as described
(Item 5.2).
