4.15 Motion Parameters Setting
The default setting of output pulse width for PCI-8136M is 2 micro seconds
and the control loop cycle time is 4.096ms. The setting could be changed by
M_Set_Sytem_Param() function according to the following table.

If the stepping motor or pulse type servo driver is used, the pulse width and
maximum motor speed must be set properly. If a voltage command servo
driver is used, the loop cycle time could be set higher as fast as the computer
is capable to run. If the system becomes unstable, please return to the
default setting.
