Chapter 1 Introduction

1.1 Introduction

PCI-1242 is a 4-Axis Pulse-type Motion Control Card and PCI-1241 is a

4-axis Pulse/Voltage-command Motion Control Card. In pulse output

control, these motion control cards use a synchronous DDA (Digital Dif-

ferential Analyzer) pulse generator to send out pulses evenly and simulta-

neously, which successfully realizes synchronous four-axis positioning

and motion control.

With a powerful control library, it is suitable for the pulse-type servo

motor or stepping motor control. It also can read back motor encoder val-

ues through the encoder’s input interface.

PCI-1241 provides a proportional control algorithm, which generates

voltage output signals between –10V and 10V to drive velocity-type

servo motors. This means it can be used for multi-axis precision servo

control.

There are three input points for each axis control, including Home posi-

tion, upper travel limit, and lower travel limit. In addition, there is a

servo-on signal output point for each axis. A position ready output point

and an emergency stop point is available for the board.

PCI-1241/1242 also supports the PCLD-8241 remote I/O module that

saves wires. PCLD-8241 provides 64-ch isolated digital input, 64-ch iso-

lated digital output and the output channels support both sink type and

source type output. PCI-1242 can connect with one PCLD-8241 module

and PCI-1241 can connect with two PCLD-8241 modules.
