ASDA-A2 Chapter 6 Control Mode of Operation

6.6.2 The Use of Torque Limit

The issuing method of torque limit command and torque command is the same. The command
source could be external analog voltage or internal parameters (P1-12 ~ P1-14). Please refer to
section 6.4.1 for descriptions.
Torque limit can be used in position mode (PT, PR) or speed mode (S). It is used for limiting the
motor torque output. When the command in position mode is issued by external pulse or the
command in speed mode is issued by external analog voltage, DI signal is enough and can be
regarded as TCM0 ~ TCM1, which is used to determine torque limit command (internal
parameters). If the DI signal is not enough, torque limit command can be issued by analog voltage.
When the disable/enable torque limit function in P1-02 is set to 1, the torque limit function is
enabled. See the timing diagram as below.
