Travel operation is suspended when overtemperature is detected. An error signal is sent
to the bus master via the bus. Operation can only restart after the supply voltage is shut
off.
•
The motor windings are only checked for interruption when supplied with hold current,
not during drive operation. The corresponding output is shut off. The other coil winding
is supplied with hold current. An error signal is sent. Operation can only restart after the
supply voltage is shut off.
•
The corresponding output is shut off. The other coil winding is supplied with hold cur-
rent. An error signal is sent. Operation can only restart after the supply voltage is shut
off.
•
The corresponding output is shut off. The other coil winding is supplied with hold cur-
rent. An error signal is sent. Operation can only restart after the supply voltage is shut
off.
An error signal is sent to the microcontroller by clamping the bus to ground for 3 sec-
onds. If the error should occur during a data transmission, the above described
reactions will happen immediately except for the clamping. This will take place about
200 µs after the end of the stopbit of the lowbyte to guarantee a correct command rec-
ognintion in the second headlamp. The error signal timing is shown in Figure 15.
