1) Shaded parts in Table show the codes for which different setting values are set in M1 to M2
(M3) in the operation with reduced number of inverters.
Set the same setting values for other codes in M1 up to M2 (M3).
2) ACR constant *2 should be less than the standard set value when operating at direct parallel
connection. (Adjustment the constants while operating the motor.)
Use the reference setting values in the operation reduced to one unit of the inverter.
3) Use motor constants by assigning motor M2 selection and motor M3 selection [MCH2,
MCH3] of the X terminal function.
Table below indicates the setting values of motor constants in the cases of the direct parallel connection
system of two or three units of inverters and a single inverter, taking the motor constants of a 280 kW
motor as an example.
