Parameter
Number Parameter Name Description
P2.11.1 Firemode Freq Frequency to be used in when fire mode is activated. This will be hidden if in Multi-Pump Mode
Parameter
Number Parameter Name Description
P2.12.1 Number of motors Total number of motors/pumps used with the Multi-Pump System
P2.12.2 Interlock function Input tells the drive if a motor/pump is connected or not
P2.12.3 Include FC Input tells the drive if the motor/pump is included in the autochange and interlock system
P2.12.4 Autochange Autochange will rotate the starting order/priority of the motors in the system to get equal wear on all motors
P2.12.5 Autochange interval Defines how often to rotate starting order of motors/pumps
P2.12.6 Autochange:
frequency limit
An autochange is done when the autochange interval has elapsed and the drive is running below autochange
frequency limit
P2.12.7 Autochange:
motor limit
An autochange is done when the autochange interval has elapsed and the number of running motors is less than
autochange motor limit
P2.12.8 Bandwidth Percentage of the setpoint defining when motor disconnection of removal will not take place
P2.12.9 Bandwidth delay With feedback outside the bandwidth, this time must pass before pumps are added or removed
