Indramat ECODRIVE Controller

This warning indicates that a parameter storage procedure is currently running within the drive controller. During this process, the drive's parameters are being written to non-volatile memory. It is critical not to switch off the drive power while this warning is displayed, as doing so could lead to parameter loss or corruption.

This warning indicates that the currently effective acceleration value in the position command value is zero. This can occur if a selected positioning block has been parameterized with an acceleration of a=0. Operating with zero acceleration in interpolation modes can lead to unexpected motion profiles or lack of movement.

In "drive-internal interpolation" and "block-controlled mode", a positioning speed must be entered in parameter S-0-0259. This warning is generated if the value set in S-0-0259, Positioning speed, exceeds the permissible maximum value defined in S-0-0091, bipolar speed limit value. This indicates a potential attempt to command a speed beyond the drive's or application's safe operating limits.

The temperature of the heatsink in the ECODRIVE DKC01.1/DKC11.1 drive controller has reached the maximum allowable warning temperature. The drive continues to follow the command value for 30 seconds, allowing for a controlled shutdown before an F218 shutdown occurs.

As soon as the motor temperature warning threshold (145°C) is exceeded, warning E251 is generated. The ECODRIVE DKC01.1/DKC11.1 drive continues to comply with the command value. A shutdown (F219) occurs only if the temperature error threshold (155°C) is exceeded.

The internal or external braking resistor (bleeder) has reached a high operating temperature, nearing its maximum permissible limit. This warning indicates that continuous operation under these conditions may lead to an F220 shutdown of the ECODRIVE DKC01.1/DKC11.1 drive.

This warning indicates that the ECODRIVE DKC01.1/DKC11.1 speed controller is entering its limit, meaning the acceleration capacity of the drive has been exceeded. In position control mode, this results in an ever-increasing deviation between command and actual values (lag error).

When using the 'command controlled operation' mode, the target position of the selected additive process block is verified. This warning occurs if the target position lies outside the represented or permissible travel range for the ECODRIVE DKC01.1/DKC11.1 drive.

The mechanical system energy reflected via the motor was so large for a moment that the bleeder could not completely convert it to heat. This caused the DC bus voltage in the ECODRIVE DKC01.1/DKC11.1 drive to rise above the maximum allowable value. The motor is then switched to torque-free operation, and the controller will turn on again if the DC bus voltage falls below the maximum allowable value.

The drive has received a command value that resulted in the axis reaching a position outside the defined positive travel range. The axis is stopped by setting the velocity command value to zero. This is treated as a warning when Bit 2 of S-0-0090 (Command Value Transmit Time - TMTSG) is set to "Exceeding the travel limit is considered as a warning", allowing automatic recovery if command values lead back to the valid range.

The drive has received a command value that resulted in the axis reaching a position outside the defined negative travel range. The axis is stopped by setting the velocity command value to zero. This is treated as a warning when Bit 2 of S-0-0090 (Command Value Transmit Time - TMTSG) is set to "Exceeding the travel limit is considered as a warning", allowing automatic recovery if command values lead back to the valid range.

The temperature of the heatsink in the ECODRIVE DKC01.1/DKC11.1 drive controller has reached the maximum allowable temperature. After 30 seconds of this condition, the drive reacts according to parameter P-0-0119 (Best Possible Deceleration) to bring the motor to a standstill.

The motor temperature has risen to an unacceptable level. As soon as the temperature error threshold (155°C) is exceeded, the drive will immediately bring the motor to a standstill as set in parameter P-0-0119 (best possible standstill).

The drive has detected that the regenerated energy from the machine's mechanism via the motor has exceeded the power capability of the bleeder resistor. To protect the bleeder from temperature damage, the drive will shut down according to the configured error reaction.

The drive controller monitors the DC bus voltage. If the DC bus voltage falls below a predefined minimal threshold, the drive independently shuts down, triggering the configured error reaction. This protects the drive from operation with insufficient power.

The drive was unable to process the given command value, resulting in a deviation from the commanded position/velocity that exceeded an allowable limit. The drive reacted by shutting down according to the set error reaction to prevent mechanical damage or uncontrolled movement.

An error was detected during the evaluation of the motor encoder signals, indicating an issue with the encoder feedback. This error typically signifies corrupted or missing encoder pulses, affecting the drive's ability to accurately determine motor position or speed.

The internal battery, typically used for backing up encoder position data (e.g., absolute encoder) or internal parameters, has fallen below its minimum voltage threshold. This can lead to loss of position reference or stored data if not addressed.

This fault indicates that a digital output on the drive controller has exceeded its permissible current limit or experienced a short circuit. The drive triggers a shutdown to protect the output circuitry from damage. The specific current limit may vary depending on the output channel, with some outputs having a limit of 350mA and others 80mA.

When the drive controller with an absolute (multiturn) encoder is powered off, the actual feedback position is stored. Upon power-up, this stored position is compared to the position reported by the encoder. If the deviation between these two values is larger than the value parameterized in P-0-0097, AbsoluteEncoderMonitoring Window, this error is generated. This can indicate movement during power-off, an initialization issue, or an encoder defect.

This is a fatal error indicating an internal short circuit within the ECODRIVE DKC01.1/DKC11.1 drive's power stage, leading to excessive current flow. This fault immediately causes the drive to shut down to prevent further damage.

The ECODRIVE DKC01.1/DKC11.1 drive requires a 24V control voltage. If this voltage deviates more than +/- 20% from 24V, the drive immediately switches to torque-free operation, activates an optional brake, and switches off encoder emulation.

The voltage supply for the ECODRIVE DKC01.1/DKC11.1 drive's internal driver stage is monitored. If this voltage is detected as too low, the drive is turned off to prevent damage.

The velocity control loop of the ECODRIVE DKC01.1/DKC11.1 drive has detected an error, indicating a significant deviation between the commanded velocity and the actual motor velocity. This can result in instability or inability to maintain speed.
