Data Sheet
Exit safe start
Command 0x83
Format Quick
Data none
ticcmd ticcmd --exit-safe-start
Arduino lib tic.exitSafeStart()
In Serial / I²C / USB control mode, this command causes the “safe start violation” error to be cleared for
200 ms. If there are no other errors, this allows the system to start up.
In the Tic Control Center, the green “Resume” button in the lower left will additionally exit safe start if
the control mode is Serial / I²C / USB.
Enter safe start
Command 0x8F
Format Quick
Data none
ticcmd ticcmd --enter-safe-start
Arduino lib tic.enterSafeStart()
If safe start is enabled and the control mode is Serial / I²C / USB, RC speed, analog speed, or encoder
speed, this command causes the Tic to stop the motor (using the configured soft error response
behavior) and set its “safe start violation” error bit. If safe start is disabled, or if the Tic is not in one of
the listed modes, this command will cause a brief interruption in motor control (during which the soft
error response behavior will be triggered) but otherwise have no effect.
In Serial mode, an “exit safe start” command is required before the Tic will move the motor again. In
the speed control modes, the input must be moved to a neutral position before the Tic will exit safe
start and move the motor again. See Section 5.4 for more information about safe start.
