TORQUE MONITOR FUNCTION
This is a function for monitoring motor presumed output torque
when sensorless vector control, 0Hz domain sensorless vector
control, and vector control with sensor are selected in selection
method.
When monitor is carried out in digital operator, select display
code d012.
When monitor is carried out in control terminal, refer to the explanation about another section of the chapter4, FM
terminal, AM terminal, or AMI terminal.
When control method is selected VC, VP1.7 power or free V/f setting, take care that this function is
invalid, and display or output signal of control terminal is unstable.
Torque monitor value of this function displays 100% output torque when the motor rotates at
synchronized
revolution in the rated frequency equivalent to the rated output of the motor.
This funcion presumes output torque prior to motor current, therefore error is about 20% when the
motor which output is same as inverter is used.
