Analog Input Configuration
The following tables show the parameter settings required for vari-
ous analog input signal types.
Analog Output Function Listing
The following table shows all three functions available for assign-
ment to the analog output terminal:
• Terminal [FM], option set by C_23
Auto-tuning Procedure
The SJ100 auto-tuning feature calibrates the inverter to the parame-
ters 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 SLV control
(set A_44 = 02). Then you can perform the auto-tuning procedure,
which is detailed in the SJ100 Inverter Instruction Manual.
