Automatic torque
boost selection
(Motor capacity)
You can set the motor capacity and exercise
automatic torque boost control.
"- - -" specifies V/F control.
Set the motor capacity used.
•
The motor capacity should be equal to or
one rank lower than the inverter capacity.
•
The number of motor poles should be 2, 4 or
6. (Only 4 poles for constant-torque motor)
•
Single-motor operation (one motor run by
one inverter) should be performed.
•
Wiring length from inverter to motor should
be within 30m (98.43feet).
When using a constant-torque motor, set "1" in
Pr. 71.
<Example> For 1.5kW, set "1.5".
