xiaomupeng2009 Posted September 27, 2011 Share Posted September 27, 2011 when i use Torque mode to control the motor,how can i detect the current of the motor in the PMAC card! Link to comment Share on other sites More sharing options...
curtwilson Posted September 28, 2011 Share Posted September 28, 2011 When the PMAC is controlling the motor with a torque-command output to the amplifier, it does not see any measurement of the motor current. A torque-mode amplifier is comparing the command value to the measured current internally, and setting a voltage to the motor to try to match the command and actual current levels. Your best estimate of the motor current is the numerical torque command output from the servo loop to the amplifier in this mode. Link to comment Share on other sites More sharing options...
