Settings; Diagnostics - ABB ACS310 User Manual

When the speed regulated motor reaches the full output, it is disconnected from the
drive and switched to direct on-line connection, with a slight delay in between.
Auxiliary motor 2 is connected to drive output. After a slight delay the motor speed is
increased to fulfil the pumping capacity needed.
Auxiliary motors 3 and 4 are started according to the same routine.
The motor stopping routine follows always the normal PFC routine.
The most important differences between PFC control and SPFC control default
settings are in acceleration time (2202), deceleration time (2203) and auxiliary motor
stop delay (8116) parameters.
