Note 1: the RDY output signal of becomes low when there is no fault to the servo and the bus voltage
has been established (if the input voltage is 230V, the bus voltage is above 150V; if the input
voltage is 400V, the bus voltage is above 380V);
Note 2: the servo enabling signal is valid when the the RDY output signal of becomes low.
