I am using P7000 Tools to setup a 3rd party stepper + NI motion controllers. I have everything working correctly, except that the motor gets hot when idle (but not killed). I know that this can be aleviated by enabling "Current Reduction" in P7000 Tools, under the "Advanced" tab. However, I'm interested to know whats actually happening and what the time and % fields control. I currently have my system to enable (on), ms (100), and % (90).
1.) I undestand that Current Reduction reduces the holding current when the motor is idle. Does this mean that my motor will support less static weight when enabled?
2.) Does the percentage field mean "reduce to" or "reduce by"? So with current reduction set to "90%", am I a reducing TO 90%, or BY 90%?
3.) What does the time field control?
4.) How does Current Reduction affect acceleration? If I'm not holding at 90%, does the motor go immediatly from 90% to 100% for acceleration?
