FM-4 Programming Module Reference Manual

Introduction

The FM-4 module is a compact and rugged function module that attaches to the front of the drive. It provides eight digital
input lines and four digital output lines, in addition to the four input and three output lines available on the drive.
Unlike other function modules, the FM-4 module offers complex motion profiling, along with multi-tasking user programs.
A complex motion profile consists of two or more indexes that are executed in sequence such that the final velocity of each
index except the last is non-zero. Logical instructions between index statements can provide a powerful tool for altering
motion profiles 'on the fly'. The FM-4 module defines complex motion by a configuration file that includes setups, function
assignments and programs. The configuration file is created using EMERSON Control Techniques PowerTools Pro software
on a PC running Windows® 98, 2000, 2003, 2008, XP (SP2) (32-bit) or Vista (32-bit) operating system. Setup views have
the same look and feel as dialog boxes. The wiring of input and output functions is done through assignments in the software.
Complete diagnostics are provided for quick troubleshooting. A diagnostic display on the front of the drive as well as the
display on the module inform the user of the operational or fault status. The last 10 faults are stored in non-volatile memory
along with a time stamp for easy recall.

Note that the drive's firmware is disabled whenever a Function Module, such as the FM-4 module is attached. Therefore, if
the drive's hardware is FM compatible, then the drive's firmware can be any ve rsion because the programming features reside
in the function module's flash memory. Flash files used for firmware upgrades are available on the Control Techniques
webpage.
The FM-4 module stores drive setup parameters within the module itself. This allows you to transfer the FM-4 module to
another drive without losing setup parameters.
