Servo Amplifier Ratings and Specifications Table 2
Notes:
*1
Supply voltage must not exceed 230V +10% (253V) or 115V + 10% (127V). A step-down
transformer is required if the voltage exceeds these values.
*2
Use the servo amplifier within the ambient temperature range. When enclosed, internal
temperatures must not exceed the specified range.
