*1 In order to avoid missing the command at the time of a communication error, maintain the state of Bit 7 = 1 on the Fault Reset command
for at least 10 ms when the communication cycle is 4 ms or less, or at least 20 ms when the communication cycle is 8 ms or less.
In order to transition from the "Switch on disabled" state to the "Operation enabled" state, it is necessary to give the
commands "Shutdown", "Switch On", and "Enable operation" sequentially. It is also possible to transition directly from the
current state to the target state with one command.
