Step pulse duration too short. Can I lengthen?

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
