Used to turn on the servo driver main power from the external
equipment. Once the servo power is turned on, it is
maintained even after this signal turns off.
This signal can be used only in the EXT. SIGNAL mode.
To prevent an internal damage after servo OFF, the interval
time is seven (7) seconds when the servo is turned on for the
number of times that is a multiple of 3.
If servo is to be turned on again for the first and second times,
the EX_SVON signal can be accepted after the SV_RDY
signal is turned off. However, be aware that an interval time is
included in the third EX_SVON signal.
