Claim 5:
6. A control method for a regenerative brake in a robot system,
the robot system including:
one or more combinations of:
a driving section configured to receive supply of electric power and generate a rotation output of an output shaft and receive supply of a rotating force to the output shaft and generate electric power;
a movable section moved by the rotation output;
a detecting section configured to detect an angular position of the output shaft;
resistor equipment having electric resistance and coupled to the driving section; and
a switch configured to turn on and off coupling of the resistor equipment and the driving section,

the control method comprising executing first braking control targeting the driving section to which the electric power is not supplied, the executing the first braking control calculating speed of the rotation output of the driving section based on an output of the detecting section and causing the switch to turn on and off the coupling of the resistor equipment and the driving section at timing determined in a time-series manner according to target deceleration determined in advance for the driving section and the speed of the rotation output.
