As part of our configured package the calibration parameters including thermal models are optimised and signed off for a particular application allowing higher phase current. CAN communications can also be configured.
Helix inverters support communication via controller area network (CAN) bus according to ISO 11898. Helix implements the Classical CAN frame format allowing bit rates up to 1 Mbit/s and payloads up to 8 byte per frame. The interface definition is defined in a DBC file shared with the customer in order to define and agree the necessary interfaces to the inverter
Safety critical messages on the CAN are protected with end-to-end counters and checksums
Helix has well-defined interfaces to support all aspects of inverter operation: torque control, speed control, fault and status reporting, for example. However, the customer can request CAN DBC modifications to facilitate the introduction of specific features and functions within the inverter control software
Helix can map an inverter to a customer motor. The process involves a combination of desktop mapping based on modelling the motor characteristics and a final dyno optimisation to ensure best-in-class torque accuracy optimisation. Application optimisation may also be required to suit the client resolver.
MCUSS is a high integrity, independent safety processor providing safety rated torque monitoring, safe state implementation and avoidance of hazardous DC voltage conditions after a crash. It features an independent processor and sensing hardware to guarantee freedom from interference. Primary MCUSS functions are:
Monitoring (and reporting) delivered motor torque
Ensuring that safe-state is achieved and maintained in the event of a safety related shutdown
Preventing exposure to hazardous levels of DC voltage after a crash.
The safety system has been developed as a System Element Out Of Context (SeooC). Helix can provide a detailed safety manual and support customers with the testing required to bring the MCUSS into the vehicle context.
