@Name
_8136_M_Set_System_Param – Set motion cycle time and speed
_8136_M_Set_IO_Active – Enable/disable motion I/O

_8136_A_Set_Source – Switch DAC source
_8136_M_Set_Feedback – Set axis0~2 encoder feedback on/off
@Description
_8136_M_Set_System_Param:
This function is for users to choose motion system's maximum
speed and motion loop's cycle time. The following table shows the
choices in PCI-8136. There are six types for speed selection, 32k,
64k, 128k, 256k, 512k, and 1024k. The corresponding pulse width
for these speeds are 32us, 16us, 8us, 4us, 2us, and 1us. If users
use pulse type motor driver, please make sure your specification.
The cycle time for motion loop is adjustable only for 512k and
1024k. The other speed types have fixed cycle time. The
corresponding cycle time for 32k, 64k, 128k, 256k are 32.768ms,
16.384ms, 8.192ms and 4.096ms. Windows NT system is not a
real time system so please choose the most suitable and stable
cycle time for your system.
_8136_M_Set_IO_Active
This function enables PEL/MEL/ALM/ORG checking when
sending pulses. For example, one user needs to use axis0 and
axis 1 for motion control. He must use this function to enable
PEL/MEL/ALM/ORG checking for these two axes. If not , these
I/Os can be us ed for general purpose I/O.
_8136_M_Switch_Logic
This function is for setting three I/O types, ORG, EL, ALM, for
generating interrupt or doing their particular job. These I/O may be
active high or low. Use this function to set their logic properly if you
use interrupt functions or motion function.
_8136_A_Set_Source
When users use one axis for closed loop motion control by
C_Initial(). The DA channel is used for generating V command
from motion pattern. This function can switch this axis for general
purpose DA channel or closed loop control mode.
