Fault 28 FCB drive functions
Error: 28.10 (1C0Ahex | 7178dec) Description: FCB 25 – Unbalanced motor phases | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Significantly different values determined in the 3 phases while measuring stator resistances. | – Check whether the motor is connected correctly. – Check all contact points on the motor and inverter. – Check the motor and motor cable for damage. | |
Error: 28.11 (1C0Bhex | 7179dec) Description: FCB 25 – High impedance motor phase | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
At least one motor phase could not be measured during motor parameter measurement. | – Check whether the motor is connected correctly. – Check all contact points on the motor and inverter. – Check the motor and motor cable for damage. | |
Error: 28.12 (1C0Chex | 7180dec) Description: FCB 25 – Stator resistance measurement timeout | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Motor parameter measurement activated while motor is turning. | – Stop motor. – Start motor parameter measurement when the motor is at standstill. | |
Error: 28.13 (1C0Dhex | 7181dec) Description: FCB 25 – Characteristic curve identification not possible | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The characteristic curve cannot be clearly identified by the motor parameter measurement. | Contact SEW-EURODRIVE Service. | |
Error: 28.15 (1C0Fhex | 7183dec) Description: FCB 25 – Timeout | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Measuring of rotor resistance, leakage inductance, and stator inductance not completed. | Contact SEW-EURODRIVE Service. | |
Error: 28.23 (1C17hex | 7191dec) Description: Minimum speed too high | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Minimum speed greater than application limit of the speed. | – Reduce the minimum speed. or – Increase the application limit. | |
Error: 28.24 (1C18hex | 7192dec) Description: FCB 05 – Limits of skip range outside setpoint limits | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The speed range of the active speed resonance skip function is larger than the permitted setpoint range. Both the minimum speed as well as the application limit lie within the skip range. As such, each setpoint falls within the skip range. | – Adjust the speed resonance range skip function. – Adjust the minimum speed. – Adjust the application limit. | |
