This chapter provides information you should know before using the product.
About the Board
This product is a PCI board that supports stepping motors and ("pulse string input" types of)
servomotors.
SMC-4DF-PCI can perform motor control for up to 4 axes.
SMC-8DF-PCI can perform motor control for up to 8 axes.
Multi-axis independent control and linear/circular interpolation control are performed via a motor driver
unit. It can store positioning information for up to 1024 frames per axis and control multiple axes
simultaneously. In addition, it can override speed/target positions during operation. Windows driver is
bundled with this product.
These various functions make it possible to build complex positioning control systems for variety of uses
such as manufacturing devices and test devices.
Features
- Capable of multi-axis independent control and pulse output up to 6.5Mpps
SMC-4DF-PCI : Control for up to 4 axes and motor control pulse output up to 6.5Mpps are available.
SMC-8DF-PCI : Control for up to 8 axes and motor control pulse output up to 6.5Mpps are available.
Command pulse for motor control supports common pulse, independent pulse and 90°C phase
difference pulse.
Limit input 3channels/axis, general-purpose input 7channels/axis, and general-purpose output
3channels/axis are equipped. Also, depending on the software setting, 6 general-purpose inputs can
be used as alarm inputs, and general-purpose outputs as deviation counter clear outputs.
- Capable of various control operations such as positioning, linear/circular interpolation, frame
continuous operations, synchronization control, and so on
Various control operations such as positioning, origin returning, linear/circular interpolation, S-curve
acceleration/deceleration, frame continuous motion, synchronization control, and so on are available.
Changing speed/target position during operation is available.
" PCL6045 series" from Nippon Pulse Motor CO., LTD. is used as the motor control IC.
- Provided with various input/output formats enabling connection to an encoder input circuit as well as
pulse output circuit.
Encoder input circuits can be connected with differential output, TTL level output, and open-collector
output. Pulse output circuits can be connected with differential input, opto-coupler and TTL level
input.
- Capable of storing positioning information up to 1024 frames for each axis and control without extra
CPU load
The parameters which are necessary for motor operations such as travel distance, travel speed,
acceleration/deceleration rate, and so on as 1 frame can be stored up to 1024 frames for each axis. In
addition, the control from the ending of 1 frame to the beginning of the next frame is mainly
performed by hardware, complex continuous positioning can operate at a high speed. It is possible to
repeatedly execute the frame after executing a frame once (loop operation).
