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.
