Siemens A07926

What the Fault Means

Alarm: Drive: Envelope curve parameter invalid

Likely causes

• Invalid parameter values were entered for the envelope characteristic of the load monitoring
• The following rules apply for the speed thresholds: p2182 < p2183 < p2184 The following rules apply for the torque thresholds: p2185 > p2186 p2187 > p2188 p2189 > p2190 Load monitoring configuration and response must match
• It is not permissible that the individual load torque monitoring areas overlap
• Alarm value (r2124, interpret decimal): Number of the parameter with the invalid value

Solution and Safe First Checks

1. set the parameters for the load monitoring according to the applicable rules.
2. if necessary, de-activate the load monitoring (p2181 = 0, p2193 = 0).

Safety: do not work inside the panel without isolating the power; if unsure, consult a qualified technician.
