  • Features
  • Specifications
  • Models


ACS is a flexible standard platform
  • Power levels 4-80 kVA and nominal voltages 24-96 V
  • Supports AC induction, AC synchronous and brushless DC motors
  • Standard firmware with extensive configurability and an application layer for vehicle specific functionality
  •  Auto tuning functionality for pairing the controller with a motor already installed in a vehicle
  • Support for traction, pump or generator applications including functions such as hill-hold, programmable braking/acceleration characteristics and dual traction
  • Software quality is assured through development processes in compliance with Automotive SPICE© and ISO 13849-1
  • CAN communication, J1939 and/or CANopen (slave or master) with support for diagnostics and software download

Monitoring of operation for optimal performance

  • I/O version allows vehicle control to reside in the ACS, directly interfacing vehicle sensors and actuators 
  • State-of-the-art vector control with optimal efficiency throughout the full speed range

Safety and protection

  • Dual CPUs and dual feedback channels for redundant cross monitoring and supervision allows ISO13849-1, category 3 and category 2 implementation of safety functions to achieve PL = c/d
  • Limitation of the output as a function of motor speed, motor and controller temperature, battery voltage, DC power, DC current and/or motor torque to protect powertrain components.
