Toshiba TH Series Instruction Manual page 79

Reference: The power capacity of each servo motor is calculated by the following
equation.
(Power capacity of servo driver) = Servo rated output / 0.7
c) Example of calculating power capacity
The power capacity of TH series robot is listed in the following table.
Type of robot
TH250A
TH350A
TH180
TH350A‐T
Note: The above power capacity is required when all axes are continuously operated
under 100% load. If the power capacity is insufficient when the robot is
operated, troubles such as a drop in master power voltage, a malfunction, or
resetting of the control power may take place. Thus, the robot may not be
correctly operated.
Also, an electric current that is three (3) times the rated current may be
required at the start of the robot. Thus, it is necessary to select a power
supply in which the peak current of the power is three (3) times the rated
current for 100 ms.
