4-2 Function Mode 4 Functions •You can select any of the following four torque limit functions from torque limit selection b040. Sets torque limits 1 to 4 (b041 to b044) for four quadrants (forward power running, regeneration, reverse power running, and regeneration). Switches over torque limits 1 to 4 (b041 to b044), depending on combinations of torque limit switchings 1 and 2 (TRQ1 and TRQ2) allocated to multi-function inputs. Selected torque limit values are enabled for all operation modes. Sets a torque limit value depending on the voltage applied to terminal 02 on the control terminal block. 0 to 10 V correspond to torque limit values of 0% to 200%.
Selected torque limit values are enabled for all operation modes. Enabled when an optional 3G3AX-DI01 board is used. For details, refer to the optional board instruction manual. •If the torque limit enable function (TL) is set for a multi-function input, the torque limit function set in b040 is enabled only when TL is turned on. When TL is off, the torque limit setting is disabled, and the maximum value is defined as the torque limit value. Unless the torque limit enable function (TL) is set for a multi-function input, the torque limit function set in torque limit selection b040 is always enabled.
•With this function, the torque limit value is set with the Inverter's maximum output current as 200%. This means output torque varies depending on the combination of motors. Note that the torque limit value is not the absolute one. •When the torque limit signal is selected in the multi-function output selection, the torque limit signal is turned on when the above torque limit function is activated. •The following figure shows torque limits 1 to 4 with "00" (four-quadrant separate setting) selected in torque limit selection b040.
