However, other controlsare available with SPCU (activated when SSC=oFF)v OffParameters affected when SSC = oFFParameter StatusDescriptioncodeACC controlled by Acceleration time, see page 52.dEC voltage variation Deceleration time, see page 52.SPCU active Start-stop profile control voltageNote: SSC is set to oFF when dLtA =dLt. In this case, SSC value is not used and is not relevant.SPCU M Start-stop profile control voltage R/W* 0Acceleration and deceleration are controlled by voltage variationNote: SPCU is forced to "profile 0" when dLtA = dLt. SPCU is inactive When SSC = On.In these cases, SPCU values are not used and are not relevant.0123v Start-stop profile 0: open loop with simple voltage ramp-up.v Start-stop profile 1v Start-stop profile 2v Start-stop profile 3Profiles 1, 2 and 3, are controlling voltage ramp-up with reduction of the over-torque at the end of starting.Advice : evaluate behavior on the application from profile 0 up to profile 3. If the application is instable, come backto the previous profile.Torquetime(1)Only available when Advanced mode LAC page 50 is set to On.*: Write only when the soft starter is stopped54 BBV51330 08/2012
