*1 The current becomes the maximum during the excited-phase detection of the servo motor performed when the servo is
turned on for the first time following the power on. (Normal: Approx. 1 to 2 seconds, Maximum: 10 seconds)
*2 The current becomes the maximum during the excited-phase detection performed when the servo is turned on for the first
time following the power on. (Normal: 100 msec)
*3 The ambient operating temperature of a ROBONET system is 0 to 40qC.
