2. Servo ready is trouble-free output after CPU is reset and main power is connected,.
3. Before servo drive is ready, main power should be connected and all control signal be ignored.
4. When So-07 =0 or 1, after servo on is ready, please wait for at least 100ms before sending control signal,
otherwise control signal might be gnored.
