SINAMICS S110 List Manual (LH7), 06/2012, 6SL3097-4AP10-0BP3
Remedy: - connect the data line to power unit and restart the CU (POWER ON).
- check or replace the CU.
- Check the cable between the CU and power unit.
- after correcting the topology, the parameters must be again downloaded using the commissioning software.
F07801 Drive: Motor overcurrent
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: The permissible motor limit current was exceeded.
- effective current limit set too low.
- current controller not correctly set.
- motor was braked with an excessively high stall torque correction factor.
- U/f operation: Up ramp was set too short or the load is too high.
- U/f operation: Short-circuit in the motor cable or ground fault.
- U/f operation: Motor current does not match the current of Motor Module.
Note:
Synchronous motor: Limit current= 1.3 x p0323
Induction motor: Limit current= 1.3 x r0209
Remedy: - check the current limits (p0323, p0640).
- check the current controller (p1715, p1717).
- reduce the stall torque correction factor (p0326).
- increase the up ramp (p1318) or reduce the load.
- check the motor and motor cables for short-circuit and ground fault.
- check the Motor Module and motor combination.
F07802 Drive: Infeed or power unit not ready
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: After an internal power-on command, the infeed or drive does not signal ready.
- monitoring time is too short.
- DC link voltage is not present.
- associated infeed or drive of the signaling component is defective.
- supply voltage incorrectly set.
Remedy: - increase the monitoring time (p0857).
- ensure that there is a DC link voltage. Check the DC link busbar. Enable the infeed.
- replace the associated infeed or drive of the signaling component.
- check the line supply voltage setting (p0210).

A07805 (N) Drive: Power unit overload I2t
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: Alarm threshold for I2t overload (p0294) of the power unit exceeded.
The response parameterized in p0290 becomes active.
See also: p0290 (Power unit overload response)
Remedy: - reduce the continuous load.
- adapt the load duty cycle.
- check the assignment of the rated currents of the motor and Motor Module.
Reaction upon N: NONE
Acknowl. upon N: NONE
