(*)The values are the standard values at 20°C and the tolerance is "10%.
The speed–torque characteristics very depending on the type of software, parameter
setting, and input voltage of the digital servo motor. (The above figures show average
values.) These values may be changed without prior notice.
The 2000 to 3000 rpm range of this servo motor is the intermittent operation range,
and is used mainly for positioning. In the intermittent operation range (S3 to 60%),
ON operation of six minutes and OFF operation of four minutes in a 10-minute cycle
is possible.
