Introduction
Sevcon Gen4 controllers are designed to control 3-phase AC induction motors and Permanent
Magnet AC (PMAC) motors in battery powered traction and pump applications. A range of
models is available to suit a wide number of applications and cooling regimes.
The controller adapts its output current to suit the loading conditions and the ambient in which it
is operating (temporarily shutting down if necessary). It will also protect itself if incorrectly wired.
Signal wiring and power connections have been designed to be as simple and straight forward
as possible. Analogue and digital signal inputs and outputs are provided for switches, sensors,
contactors, hydraulic valves and CAN communications. These electrical signals can be mapped
to Gen4’s software functions to suit a wide range of traction and pump applications.
NOTE:
Given Gen4’s mapping versatility it is important to ensure you map your application
signals to the correct software functions (see ‘Object mapping’ on page 6-11). A common
configuration is supplied by default which may suit your needs or act as a starting point for
further configuration.
Configuration and control of Gen4 is fully customizable using
Sevcon’s Calibrator handset or
DVT, an intuitive Windows based configuration software tool.
A single green LED is provided to give a visual indication of the state of the controller. This signal
can be replicated on a dashboard mounted light for example.
