SMC-4DF-PCI, SMC-8DF-PCI

Frame (bank) sequence operation function

This product handles the set of parameters which are necessary for motor operations such as travel

distance, travel speed, acceleration/deceleration rate, and so on as 1 frame, and can store up to 1024

frames for each axis. It is possible to repeatedly execute the frame after executing a frame once (loop

operation). By storing and executing continuous multiple frames in the memory of the board, the

following benefits can be got.

- Decrease the CPU load on the PC for complex control

- Shorten the idling time for the operation switchover of each frame

- By combination with synchronization control function, multi-axial continuous interpolation control

is available.

Difference in minimum time when possible to the frame (bank) sequence operation by system

configuration

When the time of a frame (bank) is short, the frame (bank) sequence operation might not be able to be

done normally. Time of a frame (bank) sequence operation that can be normally operated depends on the

speed of CPU. Information on PC (CPU and Chip Set), the number of axes for operation, and

time of operation a frame that confirms normal operation are showed in the following table.

Table 4.1. When it inserts in the expansion slot of a personal computer

CPU / Chip Set / Number of operation axes Time of a frame (bank) sequence (Min.)

Core 2 Duo E6300 / Q965 / 1 axis 200μsec

Core 2 Duo E6300 / Q965 / 4 axes 200μsec

Core 2 Duo E6300 / Q965 / 8 axes 400μsec

Pentium III 800MHz / i815 / 1 axis 400μsec

Pentium III 800MHz / i815 / 4 axes 600μsec

Pentium III 800MHz / i815 / 8 axes 800μsec

Table 4.2. When CONTEC's expansion unit ECH(PCI)BE-H2B, ECH(PCI)BE-H4B,

ECH(PCI)BE-F2B, ECH(PCI)BE-F4B and ECH(PCI)BE-H4A are used

CPU / Chip Set / Number of operation axes Time of a frame (bank) sequence (Min.)

Core 2 Duo E6300 / Q965 / 1 axis 200μsec

Core 2 Duo E6300 / Q965 / 4 axes 200μsec

Core 2 Duo E6300 / Q965 / 8 axes 400μsec

Pentium III 800MHz / i815 / 1 axis 500μsec

Pentium III 800MHz / i815 / 4 axes 600μsec

Pentium III 800MHz / i815 / 8 axes 900μsec

These values may not be satisfied depending on the system configuration including other boards and

applications.
