(*1) Use amplifier and motor as a specified pair of types given in the table of 9.3 (3) (d).
If the RYS401 (0.4 [kW]) type amplifier and GYS201 (0.2 [kW]) motor (which is a step smaller than the optimum combination) is
combined as a pair, allowable breakdown (max.) torque of 0.2 [kW] motor can be obtained as 450% (in the case of the breakdown
torque of the motor itself is 450% and above) of the rated torque.
Furthermore, in this case, other data are as follows :
• The moment of load inertia after conversion into motor shaft extension is at most 30 times the moment of inertia of motor rotor.
• Acceleration/deceleration time up to rated speed is 2 [ms] or more.
• The motor shaft extension is directly mechanically connected and is subjected to no external radial or thrust force.
