Figure 4.6: General/PtP Configuration Page
4.3.3 System Configuration
Some important system parameters are defined in this page.
Interpolation Time: Since a software driver calculates the interpolation
of PCI-1241/42, the interpolation time defines how often the motion card
will raise interpolation requests to the CPU of the system. If users set the
interpolation time to be smaller, the velocity profile will be smoother.
However, that will also consume more CPU resources. Generally, 10 ms
is recommended for most applications.
Command Mode: This setting is only for PCI-1241, which can be set as
pulse output or voltage output. For PCI-1242 and PCI-1261, it has to be
“Pulse Command”.
