Torque Control Parameter Settings

• The inverter also provides torque control, in addition to speed control and pulse train position control.
• To use this function, set the 1st Control Method (A044) to 05 (Sensor vector control) and the V2
Control Mode Selection (P012) to 00 (Speed control mode).
• To use torque control, allocate one of the Multi-function Input S1 to S8 Selection (C001 to C008) to
52 (ATR: Torque command input permission). The torque reference input is enabled when the
terminal ATR is ON.
• In the Torque Reference Input Selection (P033), select whether to input the torque reference via an
analog input terminal or the Digital Operator.
• Because, under torque control, the speed of the inverter is determined by the balance between
torque and load, set the Speed Limit Value in Torque Control (Forward/Reverse) (P039/P040) to
prevent the inverter from going out of control.
