The ER-PL PILOT is a PC based graphical configuration and diagnostic tool for use with the range of ER-PL and ER-PLX digital DC drives. It greatly simplifies drive programming, installation and commissioning.

The ER-PL PILOT is included free of charge on a CDROM with every digital drive. It makes interconnecting the drive’s application blocks a simple task and allows the user to tailor the drive’s control strategy to exactly meet the demands of the process or application. It is these abilities which further strengthens Eurotherm’s commitment to providing the user with cost effective and easy to use DC drive products.
