Schindler Altivar 312 Drive

This alarm indicates that a button on the ATV12 remote display terminal has been held down continuously for more than 10 seconds, or the keypad itself is disconnected. The keypad is designed to wake up when a button is pressed.

This fault indicates that the current drive configuration is inconsistent, possibly due to the addition or removal of an option card. An inconsistent configuration can prevent proper drive operation.

This fault indicates that an invalid configuration has been loaded into the drive, typically via the serial link. The loaded configuration is inconsistent and prevents the drive from operating correctly.

This fault indicates a detected communication issue on the CANopen bus. It implies a problem with the CANopen network connection or the CANopen option card itself.

A general communication error with a timeout of 50 ms has been detected. This message is displayed after 20 consecutive attempts at communication have failed. This is specific to the ATV12 remote display terminal.

This is a general fault code indicating the ATV12 remote display terminal has detected an unspecified internal fault within its Central Processing Unit (CPU) or other core components.

This fault indicates an issue with an optional communication card installed in the drive. It is a read-only fault code that remains stored even after the cause disappears and is reset only by cycling the drive's power. The specific values of this parameter depend on the type of network card.

This fault indicates a problem with the drive's internal capacitor precharge circuit, potentially due to a faulty precharge relay control or a damaged precharge resistor. This prevents the drive from powering up correctly and charging its DC bus.

An internal EEPROM memory fault has been detected, indicating an issue with the drive's non-volatile memory. This can affect drive configuration and operation stability.

This fault is triggered by an external condition, typically via a configured digital input. It indicates that an external device or safety circuit has signalled a fault condition to the drive.

An internal fault of unknown rating has occurred within the drive. This indicates a general internal hardware or software issue that prevents normal operation.

An internal fault related to the Human-Machine Interface (HMI) card has been detected. This could be due to the HMI card not being recognized, being incompatible, or the display not being present.

An internal EEPROM memory fault has been detected.

An internal industrial EEPROM memory fault has been detected.

This message indicates that the microcontroller within the device is currently undergoing its initialization sequence. It may also signify that the system is actively searching for communication configurations.

This fault indicates a loss of the 4-20 mA analog input signal, which is typically used for speed reference or process feedback. This can occur even if the [4-20mA loss] (LFL) parameter is set to [No] (nO) on page 95.

This overcurrent fault indicates that the motor current has exceeded the permissible limits, often due to incorrect drive or motor parameters, excessive mechanical load, or a mechanical locking condition. Sustained overcurrent can damage the motor or the drive.

This fault indicates that the internal temperature of the drive has exceeded its safe operating limits. This can be due to high ambient temperature, inadequate ventilation, or excessive load.

This fault is triggered by excessive motor current, indicating the motor is drawing more current than its thermal protection limits. An incorrect [Cold stator resist.] (rSC) parameter value can also lead to this fault. Continued operation under overload conditions can damage the motor.

This fault occurs when one or more phases are lost at the drive output to the motor. This can be caused by disconnected motor cables, an open output contactor, or operating with a motor whose power rating is too low for the drive. Instantaneous instability in the motor current can also trigger this fault.

This fault indicates that the incoming line voltage supply to the drive is too high or disturbed. Operating the drive with excessive input voltage can damage internal components.

This fault indicates that the DC bus voltage within the drive has exceeded its safe operating limits, often referred to as "overbraking." This usually happens when the motor regenerates energy back into the drive during deceleration, and there's no braking resistor to dissipate it.

This fault signifies a loss of one or more input phases to the drive. This can be due to incorrect power connection, a blown fuse, or using a three-phase drive on a single-phase line supply, especially under load. This protection only activates when the drive is operating under load.

This fault indicates a short-circuit or grounding fault at the drive output, affecting the motor connection. It can also be triggered by significant ground leakage current if multiple motors are connected in parallel to the drive.

This fault indicates an interruption in communication on the Modbus bus. It can also be triggered if a remote display terminal is enabled ([HMI command] (LCC) = [Yes] (YES), page 61) but is disconnected.

This overspeed fault indicates that the motor speed has exceeded its commanded or permissible limits. This typically results from system instability or an excessively high driving load, which can lead to loss of control.

This fault indicates insufficient line supply voltage, a transient voltage dip, or a damaged precharge resistor. The drive trips if the line voltage drops below specific thresholds: 160V for ATV312 M2/M3 models, 300V for N4 models, and 430V for S6 models.

This fault indicates an issue with the brake control system, where the brake release current may not have been reached or the brake engage frequency threshold ([Brake engage freq] (bEn)) is incorrectly set or not assigned despite brake control ([Brake assignment] (bLC)) being active. This can lead to improper motor braking or starting.

This error indicates a mismatch between the brand or type of the connected drive and that expected by the ATV12 remote display terminal.

The ATV12 remote display terminal has detected an anomaly in its Random Access Memory (RAM). This indicates a potential hardware issue with the terminal's volatile memory used for temporary data storage.

The ATV12 remote display terminal has detected an anomaly in its Read-Only Memory (ROM), typically identified through a checksum calculation failure. This indicates a potential hardware issue with the terminal's firmware storage.

This fault indicates that the auto-tuning procedure, which measures motor parameters, was unsuccessful. This can happen if motor parameters are incorrectly configured prior to auto-tuning, or if the procedure is interrupted.
