Fault 9 Control mode
Fault: 9.1 (0901hex | 2305dec) Description: Magnetization of motor not possible | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
User-defined current limit or output stage monitoring reduced possible maximum current to such a degree that required magnetizing current cannot be set. | – Reduce output stage utilization by reducing the PWM frequency or reducing the load. – Increase the user-defined current limit. – Connect a smaller motor. | |
Fault: 9.2 (0902hex | 2306dec) Description: Operating mode not possible with active control mode | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The active control mode does not support the operating mode selected in the current FCB. EXAMPLE: The V/f control mode does not support the FCB "Position control" or "Torque control". | – Use a control mode that allows the required operating mode. You might have to connect an encoder. or – Choose an operating mode that is supported by the current control mode. | |
Fault: 9.3 (0903hex | 2307dec) Description: Absolute rotor position not available | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The active control mode requires an absolute rotor position. The encoder selected as the source for the actual speed does not provide an absolute rotor position. | – Use an absolute encoder. or – Identify the rotor position using FCB 18. | |
Fault: 9.4 (0904hex | 2308dec) Description: Correct current supply of motor not possible | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
With active current monitoring during premagnetization, the required current could not be impressed into the motor. | – Check the motor supply cable. – Check the motor winding connection (star, delta) – Check motor windings. – If the error occurs repeatedly, contact SEW-EURODRIVE Service. NOTE to SEW-EURODRIVE Service: Check output stage. | |
Fault: 9.5 (0905hex | 2309dec) Description: Maximum output frequency exceeded | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Maximum output frequency exceeded. | – Reduce the maximum motor speed/speed. – Reduce the setpoint. | |
Fault: 9.6 (0906hex | 2310dec) Description: Maximum model speed exceeded | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The motor speed calculated in ELSM® control mode is too high for motor control. | – Reduce the sampling cycle ("Speed/position controller sampling cycle" parameter. Reduce the motor speed. | |
Fault: 9.8 (0908hex | 2312dec) Description: Motor protection function – demagnetization | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The motor is blocked. | Check the motor for blockage. | |
Motor has already been operated at a speed below the transition speed for too long. | Check the drive selection. | |
Motor has not been started up properly. | Perform motor startup again and run the drive function "FCB 25 Motor parameter measurement". | |
Fault: 9.9 (0909hex | 2313dec) Description: Parameter measurement not possible with active motor type | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Only the parameters of an asynchronous motor or synchronous motor can be measured. | Omit parameter measurement. | |
Fault: 9.10 (090Ahex | 2314dec) Description: Rotor stall monitoring | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Current control cannot hold load torque. | Reduce the load. | |
Fault: 9.11 (090Bhex | 2315dec) Description: Standstill current function not possible | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
In ELSM® control mode, the standstill current function can only be used if the rotor position can be measured. | Activate rotor position measurement and perform the drive function "FCB 25 Motor parameter measurement". | |
Fault: 9.13 (090Dhex | 2317dec) Description: Torque control not within valid speed range | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Motor speed too low.
| – Perform motor startup again and run the drive function "FCB 25 Motor parameter measurement". – If the error occurs repeatedly, contact SEW-EURODRIVE Service. | |
The flying start function is deactivated. | Activate the flying start function. | |
The motor is blocked. | Check the motor for blockage. | |
Fault: 9.14 (090Ehex | 2318dec) Description: Transition of open-loop speed control to closed-loop speed control failed | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The motor is blocked. | Check the motor for blockage. | |
The motor accelerates too slowly. | Check the setting of the speed controller parameter "Load mass moment of inertia". | |
Ohmic resistance was measured incorrectly. | If the ohmic resistance of the motor cable is smaller than 10% of the ohmic resistance of the motor winding, deactivate the parameter "Measure stator resistance". | |
Motor has not been started up properly. | Perform motor startup again and run the drive function "FCB 25 Motor parameter measurement". | |
The drive is overloaded by mechanical sluggishness. | – Reduce the load. – Check the mechanics. – Check the drive selection. | |
Fault: 9.15 (090Fhex | 2319dec) Description: Timeout | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The parameterization of the motor model is implausible. | – Perform motor startup again and run the drive function "FCB 25 Motor parameter measurement". – If the error occurs repeatedly, contact SEW-EURODRIVE Service. | |
Fault: 9.16 (0910hex | 2320dec) Description: Deviation of motor inductance too large | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The measured motor inductance differs greatly from the inductance in the motor data set. | – Check the motor startup and perform it again. – Check the connection type of the motor winding (star/delta). | |
