The function uses two drive parameters as timer to control the movement of the motor: the
first timer is the delay to reset the command STOP, the second timer is the delay to disable
the drive. Using the DS402 protocol, the function can use other two timers, 0x2065 and
0x2067 objects, to set the delay time to open or close the motor brake.

according to the fault reaction code option.
