Fault code 25
EEPROM fault Fault when accessing EEPROM
Æ
Use parameter P802 to set the delivery status.
Æ
Reset the fault by switching off the DC 24 V supply voltage.
Æ
Reset the unit parameters.
Consult SEW Service if the fault continues to occur.
Fault code 26
External terminal Low signal on the terminal that was programmed with the "/External fault" function
(only with SBUS slave).
Fault codes 81, 82
Start condition/output open Check the motor lead for phase failure.
Reset the fault by switching off the DC 24 V supply voltage or using communication.
Fault codes 4, 84
Thermal overload of motor • Lower the ambient temperature.
• Prevent heat build-up.
• Reduce the load on the motor.
• Increase the speed.
Reset the fault by switching off the DC 24 V supply voltage or using communication.
Fault code 89
Thermal overload of brake coil
or brake coil defective, brake coil
connected incorrectly • Increase the set ramp time.
• Brake inspection (see the motor operating instructions)
• Check the brake coil connection.
• Contact SEW Service.
• If the fault is signaled shortly after the first enable, check the combination of the drive
(brake coil) and MOVIFIT
®
-FC frequency inverter.
• For combinations of "MOVIFIT
®
-FC" and "motors with one power rating lower," check the
setting of DIP switch S10/5.
Reset the fault by switching off the DC 24 V supply voltage or using communication.
Fault code 90
Output stage detection Incorrect assignment of motor/inverter; Invalid DIP switch setting
Æ
Correct the DIP switch settings.
Reset the fault by switching off the DC 24 V supply voltage or using communication.
Fault code 94
EEPROM fault Defective EEPROM
Æ
Contact SEW Service.
Fault code 97
Copy error Error during data transmission
•
Repeat copying process.
• Set the delivery status and reset the unit parameters.
