The Scott Drive family of AC Motor controllers is designed for easy integration into existing vehicles or for new OEM motive power applications. Using the latest technology and high-quality automotive grade components the SD electric motor controller range represents exceptional value and reliability for three Phase Motor control applications up to ~400kVA.

With support for both Permanent Magnet (PM) and AC Induction (ACIM) motors, the SD range can provide up to 700 Arms of motor current and bus voltages up to 900V DC continuous rating.

Communication

Ethernet TCPIP

A standard RJ45 Ethernet connection is provided for easy connection to any PC. The Ethernet port is AUTO-MDIX enabled meaning it can be connected directly to either a PC or network switch without using a cross-over cable. PC based application software is provided which can be used for initial setup, in-field firmware upgrade or to simply view to operating parameters of the Drive.

CAN Bus

The CAN 2.0 A/B bus port is provided primarily so the Drive controller can communicate with other Scott EV products or External Vehicle Control Systems. A second CAN port is available if required.

RS485

The RS45 port is included for future expandability and custom interfaces if requested. Please contact your local distributor if you wish to customize setup, control or diagnostic functions  via RS485.
