E6581595M-61313.3 If the motor does not run while no trip message isdisplayed ...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 LEDextinguished?Check the power supply and the MCCB.Is power being supplied normally?Supply the powernormally.Make a service call.Is  displayed? • The ST-CC circuit is opened. Close the circuit between CC and the terminal to whichthe ST (standby) function on the control circuit terminal is assigned.• The FRR and CC circuit is closed. Open across CC and the terminal that is assignedthe FRR (coast) on the control terminal block.• Check the always active functions selection parameter () setting. (See 6.3.2in E6581595.)Is any failure messagedisplayed?(See 1.3.1)Track down and eliminate the cause of the failure and then reset the inverter.See 13.2.Are  and a failuremessage displayed alternately?The inverter is in the process of retrying. The retry function can be disabled by normalor emergency stop operation, or by turning off the inverter. displayed?Is the LED of the RUN/STOPkey lighted?Is the LED of the RUN/STOPkey off?• Check to see that the frequency setting signal is not set at zero.• Check the settings of the frequency setting signal parameters . (See 3.2)• Check the settings of frequency setting signal points 1 and 2. (See 6.5.2 in E6581594.)• Check the operation start frequency setting to see if it is larger than the operationfrequency. (See 6.6 in E6581594.)• Check that the frequency setting (preset-speed operation frequency, etc.) is not set atzero.• 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.Refer to Section 11 for the parameter display function or Section 8 for the status motoring function.• 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 3.2.2.)• When another control mode is selected ... Change the setting of the operation controlmode selection . (See 3.2.1)• When operation panel is selected: Change the run operation selection parameter setting to 1 or 2. (See 3.2.)• You can check the setting of each input terminal on the monitor. (See 8.2.)• When another control mode is selected ... Check whether the external operationcommand is entered.YES:NO :efesotomasyon.com -Toshiba inverter,drive,servo,plc
