Section 1: Introduction

The PCL501(PC) is an economical single axis step motor controller containing 2 Kbytes of non volatile 

stored programming space. The user can write the program and then have the PCL501(PC) autostart 

the program on power up. It provides flexible, independent control of step motors from computers or any 

machine controller with a serial port. It is also capable of stand-alone operation making it an embedded 

machine controller. The easy to use Windows software, SMC50WIN, can be used to directly control motion 

and to program the PCL501(PC). The PCL501(PC) also has the ability for real time functions. A “Direct 

Mode” is used to directly control motion for Real Time Movements through serial communication. The 

PCL501(PC) has 20 commands which are easy-to-remember for direct movement of a step motor. The 

PCL501 communicates via RS485 communication and up to 32 PCL501s can be networked from one 

communications port on your PC or PLC. The PCL501PC is for single unit communication. It is a RS232 

version of the PCL501. The PCL501(PC) has 2 programmable open drain outputs and 4 TTL compatible 

inputs and can be powered with DC (5-24VDC) or AC (8-16VAC) voltages.

Description

The PCL501(PC) controller is an open-loop system, meaning that no information is sent back to the 

PCL501(PC) from the motor to verify the number of steps that were taken. A step motor is essentially a 

digital device - you give the step motor driver 10 step pulses, and the motor moves 10 steps.

The PCL501 is designed to communicate over a RS485 bidirectional serial data bus.

The PCL501(PC) provides independent programming of acceleration/deceleration, base speed (start up 

speed), max speed (running speed), and the number of steps to be taken in both relative and absolute 

positioning modes. On absolute positioning moves, the PCL501(PC) automatically determines the proper 

direction to go and the number of steps to take. The relative positioning will move a number of steps in 

the direction that the user defines. The PCL501(PC) has a high level command set including: looping, 

conditional statements, time delays, and I/O.

Hard, soft, and home limit switch inputs are provided for each axis. These features are generally required 

in most machine control designs. 4 testable inputs and 2 programmable outputs are provided per axis. 

These I/O may be used for monitoring and controlling machine operation and/or interaxis coordination. 

These I/O are accessible independent of the busy state of the axis controls. The 4 inputs are TTL/CMOS 

compatible. The 2 outputs are current sinking, open drain FETs.

The PCL501(PC) has a built-in programmable reset circuit. Reset is automatic on power-up or by pressing 

the external reset button. A CD is provided when you purchase the unit. This CD allows you to write and 

change programs that are to be stored in the PCL501(PC) for autostart use. This CD also allows you to 

save the programs onto your computer hard drive, and easily retrieve them when needed.

Technical Support

Everyone needs help on occasion. If you have problems using any of the equipment covered by this 

manual, please read the manual to see if it will answer the questions you have. Be sure to look in the 

troubleshooting section located near the back of this manual. If you need assistance beyond what this 

manual can provide, you can call the factory direct for application assistance. If possible, have this manual 

in hand. It is often helpful to have the unit connected to a computer with the software installed.
