Description
Defines the nominal motor frequency at which the
output voltage equals the motor nominal voltage:
Fiel dWeakeni ngPoint
Nominal motor frequency
Defines the nominal motor speed as displayed on the
motor rating plate.
Nominal motor speed
Defines the nominal motor power as displayed on the
motor rating plate.
kW Rated power as displayed on the inverter name plate.
Controls self -calibration process called Motor ID run.
During this process, the inverter operates the motor
and makes measurements to identify motor
characteristics and create a model used for internal
calculations.
The motor ID run process is not run. Identification
magnetization is performed depending on the motor
control mode. See
62. In identification magnetization, the motor model is
calculated at first start by magnetizing the motor for 10
to 15 seconds at zero speed (motor not rotating,
except that a permanent magnet synchronous motor
can rotate a fraction of a revolution). The model is
recalculated always at start after motor parameter
changes.
• Parameter 9904 = 1 (VECTOR: SPEED):
Identification magnetization is performed.
• Parameter 9904 = 3 (SCALAR: FREQ):
Identification magnetization is not performed.
Note: The parameter 9904 = 2 (VECTOR: TORQ) is
not functional in the ACS355 solar pump inverter.
