After receiving command of BRK_OFF, the BRAKE signal is OFF within 2ms.
The command of BRK_ OFF enables only after asigning signal of "electromagnetic brake timing (BRAKE)"
through "output1 asignment (IO_52)", "output2 asignment (IO_53)" and "output3 asignment (IO_54)"
Although BRK_ON or BRK_OFF received in Servo ON cannot be reflected in operation, the reception of
BRAKE signals is enabled.As a result, unexpected operations may occur when the SV_OFF command is
received. So be sure always to keep BRK_ON or BRK_OFF command under control.
