ASDA-M Chapter 6 Control Mode of OperationRevision December, 2014 6-556.6 Others6.6.1 The Use of Speed LimitThe maximum speed in each mode is limited by internal parameters (P1-55), not matter itis in position, speed or torque mode.The issuing method of speed limit command and speed command is the same. Thecommand source could be external analog voltage or internal parameter (P1-09 ~ P1-11).Please refer to Section 6.3.1 for descriptions.Speed limit can be used in torque mode (T) only. It is used for limiting the motor speed.When the command in torque mode is issued by external analog voltage, DI signal isenough and can be regarded as SPD0~SPD1 which is used to determine the speed limitcommand (internal parameters). If the DI signal is not enough, speed limit command canbe issued by analog voltage. When the function of disable/enable limit function in P1-02is set to 1, the speed limit function is enabled. See the timing diagram as below.6.6.2 The Use of Torque LimitThe issuing method of torque limit command and torque command is the same. Thecommand source could be external analog voltage or internal parameter (P1-12 ~ P1-14).Please refer to Chapter 6.4.1 for descriptions.Torque limit can be used in position mode (PT, PR) or speed mode (S). It is used forlimiting the motor torque output. When the command in position mode is issued byexternal 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 isnot enough, torque limit command can be issued by analog voltage. When the function ofdisable/enable torque limit function in P1-02 is set to 1, the torque limit function isenabled. See the timing diagram as below.
