An incorrect limit switch is active, or the frequency is too low to accurately detect the direction of travel for the R&M Materials Handling Frequency Converter. This can lead to unexpected stoppages or prevent movement, indicating a problem with limit switch logic or motor speed feedback.

A board fault has been detected in the R&M Materials Handling Frequency Converter, specifically indicating that the API3 board is either not installed or not functioning correctly. This could be due to power issues, incorrect wiring connections, or a faulty board component.

The R&M Materials Handling Frequency Converter is unable to stop the motor within the configured deceleration ramp due to excessive regenerative current. This fault typically occurs when the motor's kinetic energy during deceleration exceeds the drive's capacity to dissipate it or the braking resistor capacity.

The motor's temperature has exceeded its safe operating limit, or the digital input DIA4, configured for motor overtemperature protection, has been deactivated. Prolonged operation at high temperatures or lack of protection can cause motor insulation damage.

The overvoltage regulator circuit within the R&M Materials Handling Frequency Converter has been continuously active for more than 5 seconds. This indicates a persistent overvoltage condition that the regulator is struggling to manage, suggesting an ongoing issue with supply voltage or regenerative energy.

An overvoltage condition was detected by the R&M Materials Handling Frequency Converter at the moment of starting. This is typically caused by the incoming supply voltage being too high for the drive's specifications, potentially leading to immediate shutdown.

The External Stop (ES) signal is not active, indicating that the E-stop button has been pressed and needs to be released to resume operation. This is a safety feature designed to halt operations immediately.

The power unit of the R&M Materials Handling Frequency Converter has stopped functioning, possibly due to an internal fault or an Emergency Stop (E-stop) activation while the unit was running. This prevents the drive from supplying power to the motor.

An overspeed condition has been detected by the R&M Materials Handling Frequency Converter, or there is interference affecting the speed signal from the encoder connected to ENC1A. This can lead to uncontrolled motor speed, posing a safety risk if not corrected.

A significant speed difference has been detected between expected and actual motor speed, or between different speed feedback channels, by the R&M Materials Handling Frequency Converter. This can be caused by mechanical failures, issues with load measurement, or problems with encoder signals (ENC1A, ENC2A-B) including incorrect wiring.

The motor is not running, indicating a stall condition detected by the R&M Materials Handling Frequency Converter. This can be due to a mechanical failure in the gear system or a missing speed signal from the encoder connected to ENC1A, preventing the drive from detecting motor movement.
