PG DRIVES TECHNOLOGY  AC TRACTION – HAND-HELD PROGRAMMER 
1 Introduction 
 
 
The Sigmadrive Hand-held Programmer is a powerful tool that can be used to configure all Sigmadrive controllers as well as the 
Sigmagauge display. In addition to multiple programming menus, there are status and test functions with powerful, real-time 
system information, making set-up or diagnosis particularly intuitive. The Programmer also has an interface for updating the 
controller’s flash memory, as well as updating the Programmer’s own software. 
 
1.1   Interface Switch 
On the top-right-hand side of the Programmer, there is a 3-way switch that is used to select the operating mode of the 
Programmer. 
 
 
For normal Sigmadrive programming and diagnostics, this switch must be set to position 2. 
Positions 1 and 3 are for Sigmadrive and Programmer software upgrades. Refer to the section Software Upgrades later in this 
manual for more details.
