6-6-2 Torque Limit
The command source of torque limit command is the same as torque command. It can be the external
analog voltage but also can be internal parameters (P1-12 to P1-14). For more information of torque
command source, please refer to chapter 6-4-1.
The speed limit only can be used in position mode (Pt and Pr mode) and speed mode (S mode) to limit the
output torque of servo motor. When the position and speed command is the external analog voltage, there
should be surplus DI signal that can be treated as TCM0~1 used to select torque limit command (internal
parameter). If there is not enough DI signal, the external voltage input can be used as torque limit command.
When the setting value of Y in P1-02 is equal to 1, the torque limit function is activated.
The timing chart of torque limit is shown as the figure below:
Y=1 in P1-02
TCM0~1 INVALID
TCM0~1 VALID
Y=0 in P1-02
