Page Causes and corrective actions 2 Warning When the protective function is activated, the output is not shut off. Daily inspection must be performed to prevent any fault from occurring due to the adverse effects of the operating environment, such as temperature, humidity, dust, dirt and vibration, changes in the parts with time, service life, and other factors.

The motor capacity should be equal to or one rank lower than the inverter capacity. Page 2 IPM parameter initialization list The parameter settings in the following table are changed to the settings required to perform PM sensorless vector control by selecting PM sensorless vector control with the IPM parameter initialization mode on the operation panel or with Pr.


Set the holding time of Pr. Operation Screen at power-ON The monitor display appears. Page Causes and corrective actions 3 Alarm When an alarm occurs, the output is not shut off. Page 54 Precautions for use of the inverter 13 Provide electrical and mechanical interlocks for MC1 and MC2 which are used for bypass operation.
