13 13.3 If the motor does not run while no trip message is displayed ... If the motor does not run while no trip message is displayed, follow these steps to track down the cause. The motor does not run. Is the 7-segment LED extinguished? Check the power supply and the MCCB. Is power being supplied normally? M-6 Make a service call. Supply the power normally. Is displayed? • The ST-CC circuit is opened. Close the circuit between CC and the terminal to which the ST (standby) function on the control circuit terminal is assigned. • Check the setting of (always active function selection). ⇒ See section 6.3.1. Is any failure message displayed? ⇒ See section 1.3.1. Are and a failure message displayed alternately? Is the RUN key lamp lighted? Is the RUN key lamp off? displayed? YES: NO : Track down and eliminate the cause of the failure and then reset the inverter. ⇒ See section 13.2. The inverter is in the process of retrying. The retry function can be disabled by normal or emergency stop operation, or by turning off the inverter. • When operation panel operation is selected ... Press the RUN key to start the operation. • Check whether the operation panel operation frequency is set properly. ⇒ See section 3.1.2 • When another control mode is selected ... Change the setting of the operation control mode selection . ⇒ See section 5.3. • When operation panel operation is selected ... Change the setting of the operation control mode selection parameter to 1. ⇒ See section 5.3. • You can check the setting of each input terminal on the monitor. ⇒ See section 8.1. • When another control mode is selected ... Check whether the external operation command is entered. • Check to see that the frequency setting signal is not set at zero. • Check the settings of the frequency setting signal parameters , , . ⇒ See section 6.5. • Check the frequency setting signal points 1 and 2 settings. ⇒ See section 6.5. • Check that the start-up frequency is not higher than the operation frequency. ⇒ See section 6.6. • Check that the frequency setting (preset-speed operation frequency, etc.) is not set at zero. • Check that the motor is not under a too large load or not locked up. →Reduce the load if necessary. Determine the cause, using the parameter display function and the status monitoring function. ⇒ See section 11 for the parameter display function or section 8 for the status motoring function. E6581381
13.4 How to determine the causes of other problems The following table provides a listing of other problems, their possible causes and remedies. Problems Causes and remedies The motor runs in the wrong direction. The motor runs but its speed does not change normally. The motor does not ac-celerate or decelerate smoothly. A too large current flows into the motor. The motor runs at a higher or lower speed than the specified one. The motor speed fluctu-ates during operation. Parameter settings cannot be changed. How to cope with parameter setting-related problems If you forget parameters which have been reset If you want to return all reset parameters to their respective default settings M-7 E6581381 • Invert the phases of the output terminals U, V and W. • Invert the forward/reverse run-signal terminals of the external input device. ⇒ See section 6.3 "Assignment of functions to control terminals". • Change the setting of the parameter in the case of panel operation. • The load is too heavy. Reduce the load. • The soft stall function is activated. Disable the soft stall function. ⇒ See section 5.12. • The maximum frequency and the upper limit frequency are set too low. Increase the maximum frequency and the upper limit frequency . • The frequency setting signal is too low. Check the signal set value, circuit, cables, etc. • Check the setting characteristics (point 1 and point 2 settings) of the frequency setting signal parameters. ⇒ See section 6.5. • If the motor runs at a low speed, check to see that the stall prevention function is activated because the torque boost amount is too large. Adjust the torque boost amount () and the acceleration time (). ⇒ See section 5.11 and 5.1. • The acceleration time () or the deceleration time () is set too short. Increase the acceleration time () or the deceleration time (). • The load is too heavy. Reduce the load. • If the motor runs at a low speed, check whether the torque boost amount is too large. ⇒ ⇒ See section 5.11. • The motor has an improper voltage rating. Use a motor with a proper voltage rating. • The motor terminal voltage is too low. Check the setting of the base frequency voltage parameter () . ⇒ See section 6.12.5. Replace the cable with a cable larger in diameter. • The reduction gear ratio, etc., are not set properly. Adjust the reduction gear ratio, etc. • The output frequency is not set correctly. Check the output frequency range. • Adjust the base frequency. ⇒ See section 5.9. • The load is too heavy or too light. Reduce the load fluctuation. • The inverter or motor used does not have a rating large enough to drive the load. Use an inverter or motor with a rating large enough. • Check whether the frequency setting signal changes. • If the V/F control selection parameter is set at , check the vector control setting, operation conditions, etc. ⇒ See section 5.10. Change the setting of the parameter (prohibition of change of parameter setting) to (permitted) if it is set at (prohibited). * For reasons of safety, some parameters cannot be reprogrammed while the inverter is running. ⇒ See section 4.2.6. • You can search for all reset parameters and change their settings. ⇒ See section 4.2.3 for details. • You can return all parameters which have been reset to their default settings. ⇒ See section 4.2.7 for details. 13
