torque control (T)
1
Used to select the inverter control mode: speed control or torque control.
ST500 multifunction digital terminal has two related functions on torque control: torque
control banned (function 29), and speed control / torque control switching (function 46). The two
terminals must use in conjunction with FA.00 so as to switch between speed control and torque
control.
When the speed control / torque control switching terminal is invalid, the control mode is
determined by FA.00, if the terminal is valid, the control manner is equivalent to the FA.00's value
negated.
In any case, when the torque control ban terminal is valid, the inverter is fixed at speed
control mode.

☆
FA.01 is used to select the torque setting source, there are 9 torque setting modes in all.
The torque setting adopts the relative value, the 100.0% corresponds to the rated torque of
inverter. Setting range is from -200.0% to 200.0%, indicating that the maximum torque of inverter
is 2 times of the rated torque of inverter.
