Note: Set frequency (speed) values are not permitted to be inside
the jump frequency ranges, if defined. When a frequency ref-
erence value from a real-time source (such as keypad potenti-
ometer or analog input) are inside a jump frequency range, the actual
speed is automatically forced to equal the lowest point of the jump range.
Auto-tuning Procedure
The SJ300 auto-tuning feature calibrates the inverter to the parameters of
a specific motor such as winding resistance and reactance. For optimum
sensorless vector control, it is important to auto-tune during the initial
installation, and after replacing either the motor or the inverter.
Auto-tuning requires that you configure the inverter for the desired type
of vector control (set A044 = 03, 04, or 05). Then you can perform the
auto-tuning procedure, which is detailed in the SJ300 Inverter Instruction
Manual.
