PCI-1241/1242 User Manual 44
Software Limit : Besides the hardware limitation switch, PCI-1241/42
also provides a software limit as the secondary safety factor. If the soft-
ware limit was reached the motion card will stop outputting commands.
Encoder : There are three types of encoders that can be defined here.
They are A/B phase type, CW/CCW type, and Pulse/Direction type. Also
if the pulse phase was inversed you could also define that here.
Driver : The motor driver’s specifications can be input here. You can
define the motion card’s pulse output mode according to the motor driver
types. PCI-1241/42 supports CW/CCW, A/B and Pulse/Direction output
modes. You can even choose no pulse output for simulation purposes.
“Pulse Width” defines the pulse type motion card’s high-level width of
output pulse.
“P gain” is only used for voltage type motion cards, like PCI-1241. Its
default value is 40.
Hardware Limit Mode : In this column you can set the limit switch type
according to the physical limit switch. It can be normal open, normal
close, or not check. If the mode was set as “not check” here, the limit
switch status will not be updated even when acquiring with API.
