1.2 Model Designations1.2.1 Interpreting SERVOPACK Model Numbers1-31 Basic Information on SERVOPACKs1.2 Model Designations1.2.1 Interpreting SERVOPACK Model Numbers*1. You can use these models with either a single-phase or three-phase input.*2. If you use the Servomotor with a single-phase 200-VAC power supply input, derate the load ratio to 65%. Anexample is given below. If the load ratio of the first axis is 90%, use a load ratio of 40% for the second axis sothat average load ratio for both axes is 65%.((90% + 40%)/2 = 65%)*3. The same SERVOPACKs are used for both Rotary Servomotors and Linear Servomotors.*4. The BTO specification indicates if the SEVOPACK is customized by using the MechatroCloud BTO service. Youneed a BTO number to order SERVOPACKs with customized specifications.Refer to the following catalog for details on the BTO specification.AC Servo Drives Σ-7 Series (Catalog No.: KAEP S800001 23)SGD7W - 1R6 A 20 A 000Σ-7-SeriesΣ-7WSERVOPACKs4thdigit1st+2nd+3rddigits5th+6thdigits 8th+9th+10thdigits7thdigitF70 B11th+12th+13thdigits14thdigitWithout options000Maximum ApplicableMotor Capacity per AxisA 200 VACVoltageCode Specification1R6*12R8*15R5*1*27R60.2 kW0.4 kW0.75 kW1.0 kWVoltage Code SpecificationThree-Phase,200 VAC1st+2nd+3rd digits 4th digitCode SpecificationHardware OptionsSpecification8th+9th+10th digits20AInterface*3Code SpecificationMECHATROLINK-IIIcommunications referenceDesign Revision Order5th+6th digits7th digitSpecificationCodeFT/EX SpecificationSpecificationCodeBTO Specification*4NoneBNoneBTO specificationF70 For gantry applications11th+12th+13th digits14th digit
