Module booting was interrupted several times. As a consequence, the module boots with the factory setting. Possible reasons for booting being interrupted:

• Power supply interrupted.
• CPU crashed.
• Parameterization invalid.

After this fault is output, then the module is booted with the factory settings.

• Carry out a POWER ON (power off/on). After switching on, the module reboots from the valid parameterization (if available).
• Restore the valid parameterization Examples:
• Carry out a first commissioning, save, carry out a POWER ON (switch-off/switchon).
• Load another valid parameter backup (e.g. from the memory card), save, carry out a POWER ON (switch-off/switch-on).

Note:
If the fault situation is repeated, this fault is again output after several interrupted boots.

• Carry out a POWER ON (power off/on) for all components.
• Upgrade software.
• Replace the Control Unit.

The reception of setpoints from the fieldbus interface (Modbus/USS) has been interrupted.

• Bus connection interrupted.
• Controller switched off.
• Controller set into the STOP state.

• Motor overloaded
• Motor surrounding temperature too high
• Wire breakage or sensor not connected
• Motor temperature model incorrectly parameterized

• Reduce the motor load.
• Check the surrounding temperature and the motor ventilation.
• Check the wiring and the connection.
• Check the motor temperature model parameters.

Open-loop/closed-loop control parameters have had to be changed for the following reasons:

• As a result of other parameters, they have exceeded the dynamic limits.
• They cannot be used due to the fact that the hardware detected not having certain features.

The "master control by PLC" signal was missing in operation.

• Input for "master control by PLC" is incorrect.
• The higher-level control has withdrawn the "master control by PLC" signal.
• Data transfer via the fieldbus (master/drive) was interrupted.

• Check the input for "master control by PLC".
• Check the "master control by PLC" signal and, if required, switch in.
• Check the data transfer via the fieldbus (master/drive).

• Check the line supply voltage.
• Check the infeed.
• Reduce the lower DC link threshold.
• Switch out (disable) the DC link voltage monitoring.

• Check the line supply voltage.
• Check the infeed module or the brake module.
• Increase the upper DC link voltage threshold.
• Switch out (disable) the DC link voltage monitoring.

The condition "I_act = 0 and Uq_set_1 longer than 16 ms at its limit" is present and can be caused by the following:

• Motor not connected or motor contactor open.
• No DC link voltage present.
• Motor Module defective.

• Connect the motor or check the motor contactor.
• Check the DC link voltage.
• Check the Motor Module.

An incorrect commutation angle was detected that can result in a positive coupling in the speed controller. Possible causes:

• The motor encoder is incorrectly adjusted with respect to the magnet position.
• The motor encoder is damaged.
• Data to calculate the motor model has been incorrectly set.
• Pole position identification might have calculated an incorrect value when activated.
• The motor encoder speed signal is faulted.
• The control loop is instable due to incorrect parameterization.

• If the encoder mounting was changed, readjust the encoder.
• Replace the defective motor encoder.
• Correctly set the motor stator resistance, cable resistance and motor-stator leakage inductance.
  Calculate the cable resistance from the cross-section and length, check the inductance and stator resistance using the motor data sheet, measure the stator resistance, e.g. using a multimeter - and if required, again identify the values using the stationary motor data identification.
• With pole position identification activated, check the procedure for pole position identification and force a new pole position identification procedure by means of de-selection followed by selection.

• Reduce the numerator or denominator natural frequency of the current setpoint filter involved.
• Switch out the filter involved (p1656).

• Do not attempt to change over to closedloop torque-controlled operation.
• Check the encoder cable connection.

• Do not attempt to change over to encoderless operation.
• Check the encoder cable connection.

Make the ration between the multiturn resolution and the modulo range an integer number. The ratio v is calculated as follows:

• Motor encoder without position tracking (p29243 = 0):
  – For multiturn encoders:
  v = (4096 * p29247 * p29248)/(p29249 * p29246)
  – For singleturn encoders:
  v = (p29247 * p29248)/(p29249 * p29246)
• Motor encoder with position trakcing (p29243 = 1):
  v = (p29244 * 29247)/p29246

The reference point coordinate received when adjusting the encoder via connector input p2599 lies outside the half of the encoder range and cannot be set as actual axis position.

Fault value (r0949, interpret decimal):

Maximum permissible value for the reference point coordinate.

Set the reference point coordinate to a lower value than specified in the fault value.

See also: p2599 (EPOS reference point coordinate value.

For a motor with an absolute encoder, the maximum permissible encoder range is calculated by the following formula:

• For multiturn encoders: (4096 * p29247) / 2
• For singleturn encoders: p29247 / 2

After the standstill monitoring time expired, the drive left the standstill window.

• Position loop gain too low.
• Position loop gain too high (instability/ oscillation).
• Mechanical overload.
• Connecting cable, motor/drive converter incorrect (phase missing, interchange).

When the position monitoring time (p2545) expired, the drive had still not reached the positioning window (p2544).

• Positioning window parameterized too small (p2544).
• Position monitoring time parameterized too short (p2545).
• Position loop gain is too low.
• Position loop gain is too high (instability/ oscillation).
• Drive mechanically locked.

The difference between the position setpoint and position actual value (following error dynamic model) is greater than the tolerance (p2546).

• The value of p2546 is too small.
• The gain of position loop is too small.
• The drive torque or accelerating capacity exceeded.
• Position measuring system fault.
• Position control sense incorrect.
• Mechanical system locked.
• Excessively high traversing velocity or excessively high position reference value (setpoint) differences.

• Check the "reference cam" input.
• Check the maximum permissible distance to the reference cam (p2606).

See also: p2606 (EPOS search for reference reference cam maximum distance)

• Check the encoder regarding zero mark.
• Check the maximum permissible distance between the reference cam and zero mark (p2609).
• Use an external encoder zero mark (equivalent zero mark).

max distance ref cam and zero mark)

During the search for reference, when the axis reached the zero mark it also reached the end of the traversing range without detecting an edge at the binector input "reference cam".

Maximum traversing range: -2147483648
[LU] ... -2147483647 [LU]

• Check the "reference cam" input.
• Repeat the search for reference.
