Motor mechanical loss
Sets motor mechanical loss as a
percentage of motor rated out-
put (W).
Usually setting is not necessary.
Adjust in the following circum-
stances:
• 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.
