1.1 Basic Understanding of AC Servos111.1.3 Features of Σ-Series Servos1) Σ-Series SGM/SGMP Servomotors are synchronous type servomotors and have the fol-lowing features:• Size and weight reduced to one-third those ofour conventional models.Compact Servomotor for saving installationspace.• Servo performance (power rating) enhanced tothree times that of our conventional models.Enhanced power rating (kW/s) to satisfy everyneed.• A wide product range covering rated output of30 W to 750 W.Supply Voltage Rated Output100 VAC: 30 W, 50 W, 100 W, 200 W, 300 W(0.04 HP, 0.07 HP, 0.13 HP, 0.27 HP, 0.40 HP)200 VAC: 30 W, 50 W, 100 W, 200 W, 400 W, 750 W(0.04 HP, 0.07 HP, 0.13 HP, 0.27 HP, 0.53 HP, 1.01 HP)2) SGDA Servopacks are divided into the followingtwo types according to usage:• For Speed/Torque Control: SGDA-jjjS TypeThis type uses speed or torque reference input.Reference input is by analog voltage.• For Position Control: SGDA-jjjP TypeThis type uses position reference input. Referenceinput is by pulse train.TERMS Power rating (kW/s)A constant that represents response performance of a servomotor. It can be determined bydividing squared rated torque by motor inertia. Power rating is the electric power (kW) that aservomotor can generate per second.The greater the power rating, the more powerful the servomotor.1SGM typeSGMP type
