Conguraon
Before operang the pump congure the motor controller sengs so that they are suitable for
the applicaon.

change the majority of the motor controller sengs once the pump is installed on the system.
The pump is supplied with all sengs at factory default values, as shown in Table 45 on page
95. If any of the motor controller sengs are to be changed, change them before installing
the pump on the system.

via the serial interface or via the USB service port.
