 Check if the motor can be separated from the pump
 If it can be separated, set the Parameter 01-07 as 5 and carry out the parameter measurement
of the synchronous motor
 If it cannot be separated, open the safety valve, set the Parameter 01-07 as 5 and carry out
the parameter measurement of the synchronous motor

 During the automatic measurement process of the synchronous motor, the digital keypad will
show the message “tun”. After the measurement is finished, the motor automatically shuts
down, and the measurement values are stored into Parameters 01-22 to 01-25.If the digital
