mshaver Posted August 5, 2016 Share Posted August 5, 2016 I am using a Axis Expansion Board ACC-24E2A (with a Power PMAC) to drive stepper motors using step and direction outputs. The step pulses from the ACC-24E2A are low for only about 4 microseconds. One of the amplifiers I am using needs considerably longer "off" times of about 80 or so microseconds in order for it to recognize this as a step pulse. I can determine exactly what it needs for off time using a signal generator if needed. The other 3 amplifiers are a different type and model and deal just fine with the 4 microsecond off times. Is there any way to lengthen the "off" time of the step pulses going just to the 4th axis outputs of the ACC-24E2A? Thanks Link to comment Share on other sites More sharing options...
steve.milici Posted August 12, 2016 Share Posted August 12, 2016 This is set indirectly by: Gate1.PwmDeadTime. See the description in the Power PMAC Software Reference Manual for details. Link to comment Share on other sites More sharing options...
