Time-out during cyclic data reception, e.g. due to an interrupted communication link to the master or missing cyclic data.

• Check wiring of the network.
• Eliminate EMC interferences.

Trouble (configurable)

Network - Disruption of cyclic data exchange

The communication partner has interrupted the cyclic data exchange.

• Check wiring of the network.
• The slave must receive new parameterisation and configuration files by the master, in order to be able to exchange data again.

No response (configurable)

Network - Initialization error

The initialisation of the communication stack has been interrupted due to an incorrect address setting or communication configuration.

Check master/slave configuration and restart the devices.

Trouble (configurable)

Network - Invalid cyclic process data

The cyclic process data received are invalid.

Check cyclic process data sent by the master.

Trouble (configurable)

Modbus: network time-out

No valid messages have been received via the Modbus for a longer time than the time-out time set in 0x2858:002 (P515.02).

• Check communication with the master.
• Check wiring.
• Check bus termination.

Fault (configurable)

Modbus: incorrect request by master

The request by the master is invalid, e. g. invalid CRC checksum, non-supported function code, or impermissible data access.

Check request by the master:

• Value in the valid range?
• Function code valid?
• No impermissible write access? (e. g. with regard to read-only parameters)

Warning The inverter (slave) responds to the master with an error code:

• 0x01 = invalid function code
• 0x02 = invalid data address
• 0x03 = invalid data value
• 0x04 = slave device failure

Network communication faulty

In case of the Ethernet communication interface, an internal software error has occurred.

• Switch inverter off and on again.
• In the event of a power failure during a firmware download, it is required to reload the firmware via the USB module and then restart the inverter.

Trouble

POWERLINK: Loss of SoC

SoC of master was not received.

Check configuration and system setup.

Trouble (configurable)

POWERLINK: CRC error

CRC frame defective.

Check system setup.

Trouble (configurable)

Network - PDO mapping error

• Invalid PDO assignment by the master.
• Internal PDO assignment was changed and does not comply with the configuration available in the master.

Check data mapping in the master and slave.

Trouble (configurable) Setting parameters: 0x2859:003 (P515.03)

CAN: RPDO1 time-out

RPDO1 was not received within the time-out period set in 0x1400:005 (P540.05) or with the sync configured.

Fault (configurable)

CAN: RPDO2 time-out

RPDO2 was not received within the time-out period set in 0x1401:005 (P541.05) or with the sync configured.

Fault (configurable)

CAN: RPDO3 time-out

RPDO3 was not received within the time-out period set in 0x1402:005 (P542.05) or with the sync configured.

Fault (configurable)

Torque limit reached

Motor has reached the torque limit:

• 0x2949:003 (P337.03): Actual positive torque limit
• 0x2949:004 (P337.04): Actual negative torque limit

• Observe load requirements.
• Reduce motor load.
• Check set torque limits and sources for the torque limits.

No response (configurable)

Function not allowed in selected operating mode

The selected function is not permissible in the chosen operating mode.

• Selection of torque mode [-1] in 0x6060 (P301.00) with incompatible motor control in 0x2C00 (P300.00).
• Selection of invalid drive mode [0] in 0x6060 (P301.00).

• Note: selection of torque mode [-1] in 0x6060 (P301.00) with incompatible motor control in 0x2C00 (P300.00).
• Check settings of operation modes.
• 0x6060 (P301.00)

Warning

Keypad removed

The keypad was removed while the keypad control was activated.

• Plug keypad back in or activate another control source.

Fault

Fault - Brake resistor overload

The calculated thermal load of the brake resistor has reached the error threshold set in 0x2550:009 (P707.09). The regenerative energy is too high.

• Check drive dimensioning.
• Check settings for the brake energy management. Note: The error status will be reset if the thermal load falls below the error threshold - 20 %.

Fault (configurable)

• The event can only be reset after a blocking time. Setting parameters: 0x2550:011 (P707.11)

Safety option - Internal error

The safety module or safety circuit of the device was detected as being defective. The integrated safety technology is defective.

Hardware error: it is necessary to contact the manufacturer since the device must be replaced. The inverter must be replaced. Note! The user is not allowed to change inverters that come with integrated safety technology.

• The safety module must not be removed.
• The user must not carry out any repairs on the safety module.
• The safety module is not a spare part.

Fault

• The inverter is disabled immediately. The motor has no torque (is coasting).
• The event can only be reset by mains switching.

Motor overspeed

The motor speed has reached the error threshold for overspeed set in 0x2D44:001 (P350.01).

Adapt the maximum motor speed 0x6080 (P322.00) and the warning threshold or error threshold 0x2D44:001 (P350.01).

Fault (configurable)

• The event can only be reset after a blocking time. Setting parameters: 0x2D44:002 (P350.02)
