machmotion.comalarm occurred. Check the power consumed by DB resistance (Un00B) to see how many times the DB has been used. Or, check the alarm history display Fn000 to see if the DB overload alarm A.730 or A.731 was reported. Change the SERVOPACK model, operating conditions, or the mechanism so that the DB does not need to be used so frequently.
