■
Shock resistance
Install the shaft of servo motor in a horizontal direction (shown in the figure below). This shaft
should withstand shock acceleration up to 98m/s2 (when shock is applied in an
upward/downward direction) for two (2) times. However, since a precision motor encoder is
fixed to the counter-load side of the flange, any shock applied to the shaft may cause damage
to the motor encoder. Therefore, try to avoid shock to the shaft under any circumstances.
■
Mechanical strength
The axis strength of the servo motor can withstand peak torque at stall.
■
Working accuracy
The following table shows the accuracy and precision of the servo motor output shaft
(Total Indicator Reading) of the parts surrounding the shaft.
