* 1. The factory setting depends on the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given.
* 2. The setting range is from 10% to 200% of the Inverter rated output current. The value for a 200 V Class Inverter for 0.4 kW is given.
For the motor no-load current, set E2-03 to a value less than that of E2-01.
* 3. The setting range depends on the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given. The upper limit depends on the setting of
E2-01.
* 4. The same capacity as that of the Inverter will be set if the constants are initialized.

Sets the motor iron saturation
coefficient at 50% of mag-
netic flux.
This constant is automatically
set during autotuning.

Motor
mechanical
loss
Sets motor mechanical loss as
a percentage of motor rated
output (W).
Usually setting is not neces-
sary.
Adjust in the following cir-
cumstances:
• When torque loss is large
due to motor bearing.
• When the torque loss in the
pump or fan is large.
The set mechanical loss will
compensate for torque.
