Parameter Unit Description / Notes
P409 0.00...9.99
Motor Resistance [ According to
the inverter type ]
0.01
This
parameter is shown
of the display only
when in Vector
Control (P202=2)
Value estimated by the Self-Tuning routine.
The table in item 9.3 shows the stator resistance for standard, IV
pole, 60Hz, 220/380V motors.
The value of the stator resistance can also be entered at P409 directly,
if this value is known.
NOTE!
P409 shall contain the equivalent value of the stator resistance
of one phase, by supposing that the the motor is star
connected (Y).
NOTE!
If the value of P409 is to high for the motor, a disabling of the
inverter can occur due to overcurrent (E00).
