Functions
Torque Control
This function is enabled only when Sensorless Vector Control is selected for control method (A044/A244 = 03).
To operate in the torque control, allocate "52: ATR" to any multi-function input terminal. While
the ATR terminal is turned on, the torque reference input is enabled.
The torque reference source canbe seledted from two analog types, Digital Operator, etc.
using P033. When analog setting is used, the full-scale value is 200%. (When voltage is used,
10 V corresponds to 200%.)
The torque control speed depends on the balance between torque and load. To prevent the
Inverter from running out of control, set a speed limit value in P039 (forward) or P040 (reverse).
Increasing the speed/torque control switching time reduces the switching shock. The torque reference
value under this function assumes that the torque corresponding to the Inverter's rated current is
100%. Accordingly, the absolute value of torque varies depending on the motor to be combined.
Torque Bias Function
This function is used to apply a bias to the torque reference generated by torque control. This function
is enabled only when Sensorless Vector Control is selected for control method (A044/A244 = 03).
The torque bias value under this function assumes that the torque corresponding to the Inverter's rated
current is 100%. Accordingly, the absolute value of torque varies depending on the motor to be combined.
