6. IMPORTANT NOTICE OF CANopen
- The default bitrate is 125 kbps.
- In order to enable the EPC DC/DC Converter, CANopen device must be in operational
state and object 0x6200:02 must be switched ON (value 0xFD).
- Current values are shown in mA, voltage values in mV, time values in ms and power
values in W.
- Input objects show information of low side voltage connector.
- Output objects show information of high side voltage connector.
- In control mode, just one target value can be nonzero (i.e., if high side current is
desired to be controlled, low side current and high side power must be zero
commanded).
- Positive current is defined as charging current (energy goes from HVDC to LVDC
side). Negative current is defined as discharging current (energy goes from LVDC to
HVDC side).
- In case of an EPC error, the CAN - CANopen interface will send an error message to
the CANopen bus and change to pre-operational state. It is mandatory reset the
error before enabling the EPC again.
- TPDO is transmitted if one of the mapped objects changes its value.
