7 Troubleshooting ‹ Auto-Tuning Errors 30 I67E-EN V1000 Quick Start Guide LED Operator Display Cause Corrective Action Er-01 Motor data fault The input motor data are not valid (e.g. the base frequency and base speed do not fit). Re-enter the data and repeat Auto-Tuning. Er-02 Minor Fault • The wiring is faulty. • The load is too heavy. • Check the wiring. • Check the load. Always perform Auto-Tuning with the load decoupled from the motor. Er-03 The STOP button was pressed and Auto-Tuning was canceled. Repeat the Auto-Tuning. Er-04 Resistance fault • Wrong input data. • Auto tuning exceeded the given time frame. • Calculated values out of range. • Check the input data. • Check the wiring.
• Re-enter the data and repeat the Auto-Tun- ing. Er-05 No-Load Current Error • Incorrect data was entered. • Auto tuning took too long. • Calculated values out of range. Er-08 Rated Slip Error • Wrong data input. • Auto tuning exceeded the given time frame. • Calculated values out of range. Er-09 Acceleration error The motor did not accelerate for the speci- fied acceleration time. • Increase the acceleration time C1-01. • Check the torque limits L7-01 and L7-02. Er-11 Motor speed fault. The torque reference was too high. • Increase the acceleration time (C1-01). • If possible, disconnect the load. Er-12 Current detection error • One or all output phases are lost.
• Current is either too low or exceeds the drives rating. • The current sensors are faulty. • Check the wiring. • Make sure, that the drive rating fits to the motor. • Check the load. (Auto-Tuning should have been performed without the load con- nected). • Replace the drive. End1 Rated current alarm • The torque reference exceeded 20% dur- ing Auto-Tuning. • The calculated no-load current is above 80% of the motor rated current. • Check the V/f pattern setting. • Perform Auto-Tuning without the load con- nected. • Check the input data and repeat Auto-Tuning. End2 Motor iron-core saturation alarm • Calculated core saturation values out of range. • Incorrect data was entered.
• Check the input data. • Check the motor wiring. • Perform Auto-Tuning without load con- nected. End3 Rated current alarm Check the input data and repeat tuning.
