Fault Number : 87

Fault Display : IXo VoltageRange

Fault Name : IXo Voltage Range

Fault Type : None

Fault Description : Voltage calculated for motor inductive impedance exceeds 25% of [Motor NP Votls].

Corrective Action : Parameter 53 [Motor Cntl Sel] must be set to a value of 4 (FVC Vector) for this fault to occur. A calculation of motor impedance has had a problem. The setting for parameter 64 [IXo Voltage Drop] is incorrect. This can be caused by parameters 40-49 [motor nameplate data] being entered in incorrectly. A problem with the motor may also exist.

This fault is only available in the Powerflex 70 EC v2
