PCI-8174

Advanced DSP-based 4-axis Stepper & Servo Motion Control Card

Advanced DSP-based 4-axis Motion Controller

The ADLINK PCI-8174 offers an on-board DSP with motion ASIC to

easily allow implementation of time-critical motion sequences. The

DSP will execute the sequence via the motion ASIC without consuming

CPU resources, making it ideal for interrupt control and synchronization

among multiple axes. All processes are executed in the hardware

layer, so the PCI-8174 operates as a standalone controller.

Motion Control Feature

The PCI-8174 provides powerful position or speed changing function

while axis is moving. After motion begins, target of speed or position

can be changed on the fly at the user's discretion.

Linear & Circular Interpolation

In multi-axis operation, the PCI-8174 provides linear interpolation by

any 2, any 3, or even all-4 axes. Besides any 2 axes can perform

circular interpolation.

Continuous Contouring

The pre-register architecture of PCI-8174 offers the feature to build

the continuous interpolation function, ie, the 2nd motion may follow

previous motion instantly without latency. Thus perfect velocity continuity

can be established.

Hardware Position Compare and Trigger Output

The PCI-8174 provides position compare and trigger functions. The

CMP channel will output a trigger pulse when encoder counter reached

the compared value preset by user. Comparison is done by hardware

without time delay problem.

Position Latch

The latch function is to capture the instant counter value of one certain

axis when the latch signal activates. The LTC channel is used to

receive the latch pulse. The latch function is implemented with hardware.

Automatic Backlash Compensation

Whenever direction change is occurred, the PCI-8174 outputs backlash

corrective pulses before sending commands. During interpolation

mode, this function will be ineffective.

13 Home Return Modes

To fit into various mechanical design and operating restrictions, the

PCI-8174 provides 13 home moving modes for users to choose as

their best convenience.

Simultaneously Start/Stop

By using software program or external input signal, the PCI-8174 can

perform simultaneously start/stop function on multi-axis in one card or

multi-axis in multi-card. Also, the simultaneously stop function is selectable

to be active when some axes are abnormally stopped.
