External Timebase timer resolution ?

Hi, I'm wondering that what is the precision of "TM" and "DELAY" in using external timebase. In "Turbo SRM.pdf", it explaines that the resolution of "TM" is 0.5 msec when using LINEAR or CIRCLE commands. And "DELAY" is a floating point variable. But In "Turbo PMAC User Manual.pdf", there's an example about External timebase which is different from explained aboves. In this example, ... TM 585.9375 X10000 DELAY 500 TM 953.125 ... Is this sample code is right? Please confirm that what is the resolution of TM and DELAY in external timebase exactly. I think it is very important in using external timebase. Have a nice day!

In Turbo SRM it explains that: - TM is defined in msec units - In linear and circular moves has a range of 0.5 to 2^23 msec - In linear and circular moves has a floating point resolution - In Spline and PVT moves it has a range of 1 servo period to 4096 msec - In Spline and PVT moves it has a resolution of 1/4 microseconds All these also apply to the external timebase setup.
