2-7-2 Maximum speed setting
In operation of a single-axis robot with a long stroke ball screw, resonance of the ball screw may
occur. In this case, the maximum speed must be reduced to an appropriate level. The maximum
speed can be reduced by lowering the SPEED setting in automatic operation or by programming.
Use the desired method that matches your application. For maximum speed setting versus the
robot stroke length, see Chapter 4, “Specifications”.
If the maximum speed does not reach a hazardous level, reducing the speed is unnecessary even
when a robot has a long stroke axis.
CAUTION
Do not operate the robot if the ball screw is vibrating. The ball screw may otherwise
wear out prematurely.
2-7-3 Duty
To achieve maximum service life for the YAMAHA single-axis robots, the robot must be oper-
ated within the allowable duty (50%). The duty is calculated as follows:
Duty(%)=
Operation time
Operation time + Non-operation time
×
100
If the robot duty is too high, an error such as “overload” or “overheat” occurs. In this case,
increase the stop time to reduce the duty.
