8 Maximum elapsed time/maximum motion angle

8 Maximum elapsed time/maximum motion angle

8.1 Overview

The values in this chapter shows the elapsed time and motion angle until the power supply to the motor is
blocked after SS1 function is activated. When the motion speed is lower, as the time needed for deceleration
gets shorter, the processing is executed in shorter elapsed time and in less motion angle than the values shown
in this chapter. If the robot is not used properly, the maximum elapsed time and maximum motion angle may be
larger than the values in this chapter.

8-60 Overview
Meaning
Robot arm extention Rate of robot arm extension for each axis of rotation. Please refer
to "8.3 Robot arm extention rate" for details.
rate
Load rate Rate of robot load against maximum load. For example, M=66%
means that the robot load is 2.64kg for the robot whose
maximum load is 4kg.
Over The speed of robot movement.
Stopping time Maximum elapsed time until the power supply to the motor is
blocked after SS1 function is activated.
Stopping angle Maximum motion angle until the power supply to the motor is
blocked after SS1 function is activated.
Stopping distance Maximum motion distance until the power supply to the motor is
blocked after SS1 function is activated.
(only for J3 axis of RH-FH series)
