G MOTOR POWER
This parameter matches the motor rated power, adjustable between 0.7 hp and
1340 hp. The drive uses this parameter for motor overload and kWh
information displays. The left key switches the display between hp and kWh.
To change the display, press and hold the left key for two seconds.
Press [Up Arrow] or [Down Arrow] to select the motor power value for your
motor. Press [ * ] to confirm the selection and move to the next parameter.
H MOTOR POWER
FACTOR
This parameter matches the motor power factor (at rated speed and load on
sinusoidal power), adjustable between 0.10 and 1.0. The drive uses this
parameter for motor torque and power information displays.
Press [Up Arrow] or [Down Arrow] to select the motor power factor value for
your motor. Press [ * ] to confirm the selection and move to the next
parameter.
I MOTOR BASE
FREQUENCY
This parameter is used to set the designed frequency of the motor, adjustable
from 30 Hz to 500 Hz in 10 Hz increments. Changing this value will
automatically set the FWP to the same value.
Press [Up Arrow] or [Down Arrow] to select the base frequency value for
your motor. Press [ * ] to confirm the selection and move to the next
parameter.
J MOTOR BASE R.P.M.
This parameter is used to set the nameplate speed of the motor and is
adjustable from 200 to the maximum 2 pole motor speed based on Start-up
Data Parameter I (Motor Base Frequency).
Press [Up Arrow] or [Down Arrow] to set the motor nameplate speed value
for your motor. Press [ * ] to confirm the selection and move to the next
parameter.
K MOTOR NOM.
VOLTAGE
The default is 460 V for 480-volt units, 380 V for 380-volt units, and 230 V
for 230-volt units. Changing this parameter automatically changes the
Maximum Output Voltage.
Press [Up Arrow] or [Down Arrow] to select the motor rated voltage for your
motor. Press [ * ] to confirm the selection and return to Operating Data
Parameter 1 (Output Frequency).
Note: If the motor rated voltage is lower than the supply voltage, make sure
that the motor insulation is rated for the DC bus voltage level which is
