3.4.4 Instruction of commissioning process
1. If the system of multiple circulation variable frequency motors does not need the auxiliary
power frequency motor, set P22.14 and P22.15 to 0. For the system of multiple circulation
variable frequency motors+multiple auxiliary power frequency motors, set the parameters as
above table and part of the parameters such as PID1 reference according to the actual
situations. For the system of multi-motor in operation at the same time, PID1 feedback
