12.1  Overview 
This chapter describes the specifications for the positioning module, its operation, and its programming. On 
the analog input/output module, four channels receive analog signals (voltage or current), and converts those 
signals into 16-bit digital signals. In addition, the analog input/output module receives two blocks of 16-bit 
digital data from a CPU module, and converts the digital data into analog signals (voltage or current). The 
analog input/output module sends the analog signals by two channels 
12.1.1. Characteristics 
(1)  Use the AS02/04 PU-A module, based on its practical application. 
AS02PU-A: 2-axis differential output, 1 encoder 
AS04PU-A: 4-axis NPN transistor (sinking) output 
(2)  High-speed input/output 
AS02PU-A: high speed output frequency at 200 k Hz (A/B/Z phase) and 2-axis 200 k HZ differential 
output 
AS04PU: 4-axis NPN transistor (sinking) output at 100 k Hz 
(3)  Input/output 
AS02PU-A: 5 direct current input points (sinking or souring) 
AS04PU-A: 6 direct current input points (sinking or souring) 
(4)  Use the utility software to configure the module. 
The HWCONFIG utility software is built into ISPSoft. You can set modes and parameters directly in 
HWCONFIG without spending time writing programs to set registers to manage functions. 
(5)  Specially designed instructions for the module 
You can use specially designed instructions to control the modules without spending too much time to 
figure out how to achieve the required applications.
