Official Troubleshooting Steps
Message value: Parameter: %1 Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR Reaction: NONE Acknowledge: IMMEDIATELY (POWER ON) Cause: The closed-loop control parameters have been param eterized incorrectly (e.g. p0356 = L_spread = 0). Fault value (r0949, interpret decimal): The fault value includes the parameter number involved. The following parameter numbers only occur as fault values for vector drives: p0310, for synchronous motors: p0341, p0344, p0350, p0357 The following parameter numbers do not occur as fault values for synchronous motors: p0354, p0358, p0360 See also: p0310, p0311, p0341, p0344, p0350, p0354, p0356, p0357, p0358, p0360, p0400, p0404, p0408, p0640, p1082, p1300 Remedy: Modify the parameter indicated in the faul t value (r0949) (e.g. p0640 = current limit > 0). See also: p0311, p0341, p0344, p0350, p0354, p0356, p0358, p0360, p0400, p0404, p0408, p0640, p1082
