  1. The power voltage must not exceed 230V +10% (253V). If it is likely that it will exceed this limit, use a step-down transformer. For types SGDH-08AE-S and SGDH-15AE-S, voltage is 200 to 230V + 10% -5%.
  2. Use the servo amplifier within the ambient temperature range. When enclosed, the temperatures inside the cabinet must not exceed the specified range.
  3. Speed regulation is defined as follows:
    Speed Regulation = (no-load motor speed - full load motor speed) / rated motor speed x 100%
  4. Forward is clockwise viewed from the non-load side of the servomotor, (counterclockwise viewed from the load and shaft end).\
  5. The built-in open collector power supply is not electrically isolated from the control circuit in the servo amplifier.
