automatically by "P132: Motor Constant Measuring Function".
・Overcurrent trip may occur if the value of voltage compensation constant is
too large.
・The torque may be insufficient at lower speed if the value of voltage
compensation contant is too small.
・The change from manual torqe boost to auto torque boost or vice versa
cannot be made during operation.
●Please use the inverter in the following conditions when set to "auto torque
boost".
・The motor must be the squirrel-cage induction type for general purpose.
・ Please select the inverter with capacity equivalent to or one level higher
than motor capacity.
Example 1) Please select a 0.75 kW inverter for motor ranging from 0.4 kW to
0.75 kW.
Example 2) Please select a 1.5 kW inverter for motor ranging from 0.75 kW to
1.5 kW.
・Number of motor poles must be "2", "4" or "6".
・It must operate in standalone mode (i.e., one motor is driven by one
inverter).
・The maximum wiring length between the inverter and motor must not exceed
30 m.
If the above conditions are not satisfied, it is unlikely to achieve sound
operation performance.
・The output frequency for auto torque boost setting ranges from 1 Hz to 120
Hz.
