After the OFF command is received, the pumps are switched off in either of the two stop modes:
● With OFF1 command received, the pump stop mode is selected in parameter p29533 as
follows:
– p29533 = 0: normal stop
– p29533 = 1: sequence stop
● With OFF2/OFF3 command received, the pumps are switched off with normal stop.
Note
Sequence stop
During sequence stop, the motors are switched off in the reverse sequence in which they are
switched on. It is therefore important that the motor configuration parameter p29521 is not
changed while the converter is running. Otherwise, the parameter value may no longer
correspond to the mapping of the motors connected.
