·
Offline auto tuning must be performed.
·
The number of motor poles is any of 2, 4, and 6. (4 poles only for the constant-torque motor)
·
Single-motor operation (one motor for one inverter) is performed.
·
The wiring length between the inverter and motor is within 30m (98.42 feet). (If the length is over 30m
(98.42 feet), perform offline auto tuning with the cables wired.)
