(*1) 15 micrometers for over the rated speed.
(*2) Direction of gear-output-shaft rotation is CCW (counter-clockwise), when motor shaft rotates forward(*).
The direction is viewed from a point facing the drive-end of motor.
(*3) Breakdown (max.) torque and maximum current values are selected in accordance with the following paired combination of amplifier
and motor types.
Lower value/higher value：
When the same output [kW] rating of amplifier and motor/when amplifier size is one step larger than the motor frame No. size
corresponding with amplifier.
Refer to 2.3.
(*4) Rated torque are continuous operating torque , on condition that motors are mounted heat sink which size are bellow table.
