Code Name Causes Possible Solutions Er-15 Torque Saturation Error During Inertia Tuning, the output torque was more than the value set in L7-01 to L7-04 [Torque Limit]. Increase the value set in L7-01 to L7-04 [Torque Limit] as much as possible. Decrease the values set for the frequency and amplitude of the test signals used when doing inertia tuning. First, decrease the test signal amplitude, and then do Inertia Tuning. If the error continues, decrease the test signal frequency and do Inertia Tuning again.
