*1 Maximum speed available when the shaft is rotated by external force at the time of power failure or the like. Also, if power is switched on
at the servo motor speed of 3000 r/min or higher, position mismatch may occur due to external force or the like.
*2 The data-holding time by the battery using MR-BAT6V1BJ. Replace the batteries within three years since the operation start regardless
of the power supply of the servo amplifier on/off. If the battery is used out of specification, [AL. 25 Absolute position erased] may occur.
*3 The power-on time ratio of 25% is equivalent to when the power is on for 8 hours a day on weekdays and off on weekends.
