LIN Frames and Signals
MOTOROLA
C.2 Node ID
The controlled axis specifies the relation to the LIN basic messages;
each LIN Stepper Controller node relation to LIN messaging is specified
by two parameters
•
the configured axis
•
exclusive Node ID
The Node ID is used for configuration. The LIN Master Request and
Slave Response Frames (Command frames) used for configuration are
broadcast frames (each slave node acts upon them). We must

(0x1C)
l_u8_wr_AppErrFlagsA1_1
Application Error Flags. The LIN
Stepper Controller provider sends
the error byte with the flags
bit0
HighTemperature
- Power Die
over temperature
bit1
HB_OverCur
- H-bridge
overcurrent flag
bit2
HighVoltage
- H-bridge high
voltage
bit3
LowVoltage
- H-bridge low
voltage
bit4
PowerDieError
- Power Die error
bit5
LINTxRxError
-
NOT
IMPLEMENTED
bit6
SICurrLim
- serial input current
limitation
bit7
StopSpeedError
- speed was too
enough when motor stopped
(possible loss of the step - used for
software debugging)
0
1
0 - False
1 - True
l_u8_wr_analogValueA1_1
NOT IMPLEMENTED
- any analog
value like temperature, DC bus
voltage, etc. can be send out from
the LIN Stepper Controller provider
