max frequency for starting current.
Note : see the Appendix for the frequency to the revolution speed
conversion formulas, related to the number of motor poles.
Maximum motor current
The maximum motor current in the case of the compressor must be set
at 1000(=100.0%): as there is no necessity for quick accelerations, no peak
currents must be envisioned.

Motor electric data
The stator resistance is the resistance of the stator windings, measured
between phase and phase. In the mathematical model of the motor, Ld and
Lq are the inductance used in the reference system (d,q) rotating at rotor
speed.It is recommended to use the values indicated by CAREL depending
on the motors/compressors available. If the Autotuning is performed, these
parameters are set automatically at the end of the procedure on the basis of
the measurements detected.

Motor start-up
These parameters optimise the initial start-up phase of the motor and the
relative estimate of the position and the motor speed. It is recommended to
use the values indicated by CAREL depending on the motors/compressors
available. See paragraph 5.11 for the meaning of the parameters.

It is recommended to use the default values. Typically in the application with
compressors, the regenerative functioning mode never occurs. For particular

Frequency/voltage/rated current/power factor
The base frequency is the frequency at which the nominal voltage is applied.
If current peaks are necessary, the rated current of the motor must be lower
enough that the drive rated current. The power factor is the rated cos

of
the motor.
