After reset, the BLDC control MCU software is in manual mode. In order
to control the system from PC master software, it is necessary to set PC
master software mode, and then to provide the MCU software control
from PC master software via application interface variables.
Commands defined for the BLDC control MCU software are listed in
Table 3-1. The commands are very simple. If the software executes the
command, it responds with OK byte 00. If it is unable to execute the
command, it responds with failed code 55. The commands "Set PC
master software mode", "Set manual mode" can only be executed when
the START/STOP switch on the demonstration suitcase is set to STOP
and the motor is stopped. Otherwise, a failed response is sent.
