*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%. An
example is given below. If the load ratio of the first axis is 90%, use a load ratio of 40% for the second axis so
that 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 SERVOPACK is customized by using the MechatroCloud BTO service.
This service is available on the e-mechatronics website. You need a BTO number to order SERVOPACKs with
customized specifications. Refer to the following catalog for details.
