BDI_CTR_empty: e “empty” parameter for the charge-tracking-reset curve, in mV per cell.
BDI_OCR: e open-circuit reset value, in mV per cell.
BDI_integration_time: e integration time, in minutes.
B+_nominal: e nominal B+ system voltage, in volts, e.g. 24, 36, 48.
can_baud_rate_struct_length: is parameter indicates the number of CAN ports that have baud rate
denitions.
can_baud_rate: is parameter is enumerated as follows:
Value Baud Rate
-2 20k
-1 50k
0 125k
1 250k
2 500k
3 800k
4 1M
can_node_id_struct_length: This parameter indicates the number of CAN ports that have Node ID
denitions.
can_node_id: 0-127 indicating the node ID of the display.
can_pdo_timeout_period: 0-32767 indicates the time in milliseconds that the last CAN-commanded
data will be displayed. If no PDO1_RX messages are received within this time, all icons
and the backlight will turn o, Hourmeter Enable will be set to zero (stopping the internal
hourmeter from counting), and the large text display will show “***” until the next
PDO1_RX message receipt. If the large text source is “BSoC”, then the large text display
will continue to show the internal BSoC calculation.
If no PDO2_RX messages are received within this time and the small text source is set for
“CAN”, the small text display will change to “******” until the next PDO2_RX message
receipt. Otherwise, the small text display will continue to show the internal hourmeter
value.
Note: If both PDOs time out, then the unit enters Pre-operational mode. When
this occurs, the display will go blank and the backlight will turn o.
P_User_1 ~ P_User_10: ese objects are 32-bit general purpose non-volatile objects. ese objects will be
stored in EEPROM if “save” is written to canopen_store_all_parameters.
