Overtemperature

A stop with inhibit indicates thermal overload of the inverter. If a braking resistor is integrated in the heat sink, this could exacerbate the issue by generating additional heat.

F110

Ex-e protection

The maximum allowed duration for operating the motor below 5 Hz in Ex-e protection mode has been exceeded. This fault initiates an emergency stop to comply with safety regulations for explosion-protected motors, which have thermal limitations at low speeds.

F111

System bus (SBus) error

Communication between the FSE24B fieldbus interface and the MOVITRAC® B inverter has been interrupted. This fault is signaled to the EtherCAT or fieldbus master, indicating a break in the SBus connection. MOVITRAC® B itself would register an F47 internal error for this condition.

F113

Analog input wire break

A wire break has been detected at the AI1 analog input terminal. This fault indicates an open circuit in the signal path to analog input 1, preventing correct signal measurement. The response to this fault can be configured programmatically.

F116

Error application module

A general error originating from an application module, indicating a problem in the drive's specialized control functions. This fault has several specific sub-errors that further define the nature of the issue, such as encoder problems or limit switch activations.

F17-F24

System error

An immediate switch-off with inhibit, indicating a fault in the inverter electronics, potentially due to EMC issues. This is a general system error for the range F17 to F24, pointing to an internal electronic malfunction.

F25

EEPROM

A stop with inhibit, indicating an error during access to the EEPROM. This can often be resolved by restoring factory settings and parameters, suggesting a data corruption or access issue.

F26

External terminal

This programmable fault is triggered by an external fault signal read via a configurable input terminal. The response can be configured (e.g., Immediate stop, Rapid stop) based on the specific application requirements.

F31

TF/TH trip

Motor overtemperature detected by the TF sensor. This fault causes a stop without inhibiting the drive, meaning the "Ready" signal is maintained. This indicates the motor has exceeded its thermal limits and requires cooling.

F32

IPOS index overflow

An internal stack overflow has occurred within the inverter's IPOS user program. This fault is typically caused by violations of programming principles in the user-defined control logic and results in an immediate switch-off with inhibit.

F34

Ramp timeout

The drive has failed to reach the start/stop speed within the specified ramp time. This fault can occur during a controlled stop if the stop ramp time t13 is exceeded, or if the set stop ramp (P136 / P146) is too short. It causes an immediate switch-off with inhibit.

F35

Ex-e protection operating mode

An invalid operating mode was selected for Ex-e protection, or the Ex-e motor was not correctly integrated into the system. This fault triggers an immediate switch-off with inhibit, indicating a potential safety or operational violation for explosion-protected motors.

F36

Option missing

An option card is either incorrect, missing, or has incompatible settings for its setpoint source, control signal, or operating mode. This fault indicates a configuration mismatch or hardware absence, leading to an immediate switch-off with inhibit.

F37

System watchdog

An error has occurred in the fundamental system software sequence, indicating a potential internal processing issue. This fault causes an immediate switch-off with inhibit, often related to environmental electrical interference.

F38

System software

A general system error has been detected within the inverter's core software. This fault signifies a critical internal issue and results in an immediate switch-off with inhibit. It often points to electrical noise or hardware instability.

F43

RS485 timeout

Communication over the RS485 interface between the inverter and a PC, or to the FSE24B module, has been interrupted. This fault does not lock the drive and clears automatically once communication is reestablished, indicating a transient or connection issue.

F44

Unit utilization

The inverter's internal utilization (I × t value) has exceeded its safe operating limits, indicating a prolonged or excessive overload condition. This fault causes an immediate switch-off with inhibit to protect the inverter from damage.

F47

System bus 1 timeout

A stop without inhibit occurs due to a communication fault via system bus 1. This can be related to the bus connection, parameter P808, the voltage supply of the FSE24B module, or EtherCAT communication issues with the connected FSE24B.

F77

IPOS control word

A stop with inhibit occurs due to an internal system error, indicating a problem with the IPOS control word. This suggests an internal firmware or configuration issue within the IPOS logic.

F80

RAM test

An immediate switch-off occurs due to an internal unit error, specifically a defective RAM. This is a hardware fault within the inverter's memory system.

F81

Start condition

An immediate switch-off with inhibit occurs only in 'VFC hoist' operating mode. The motor could not be supplied with the correct amount of current during the pre-magnetizing time, possibly due to mismatched motor/inverter power or insufficient motor cable cross-section.

F82

Open output

An immediate switch-off with inhibit occurs only in 'VFC hoist' operating mode. This indicates that two or all output phases are interrupted, or the rated motor power is too small relative to the inverter's rated power, preventing proper motor operation.

F84

Motor protection

A stop with inhibit indicating that motor utilization is too high, often detected by IN-UL monitoring (P345/P346). This protects the motor from sustained overload conditions.

F94

EEPROM checksum

An immediate switch-off with inhibit indicates a defective EEPROM. This is a critical hardware fault in the non-volatile memory that stores configuration data.

F97

Copy error

An immediate switch-off with inhibit occurs if the parameter module is removed during a copying process or if the unit is switched off/on while copying. This indicates an interruption during data transfer to or from the parameter module.

F98

CRC error flash

An immediate switch-off indicates an internal unit error, specifically a defective flash memory (CRC error). This is a severe hardware fault in the unit's permanent storage.
