SINAMICS S List Manual (LH1), 07/2007
Note:
Synchronous motor: Limit current= 1.3 * p0323
Induction motor: Limit current= 1.3 * 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.
F07801
Drive: Motor overcurrent
Drive object:
VECTOR
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.
- V/f operation: Up ramp was set too short or the load is too high.
- V/f operation: Short-circuit in the motor cable or ground fault.
- V/f operation: Motor current does not match the current of Motor Module.
Note:
Limit current = 2 * Minimum( p0640, 4 * p0305) >= 2 * p0305
Remedy:
- check the current limits (p0640).
- vector control: Check the current controller (p1715, p1717).
- V/f control: Check the current limiting controller (p1340 ... p1346).
- increase the up ramp (p1120) 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
Drive object:
SERVO, VECTOR
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)
Infeed: Power unit overload I2t
Drive object:
A_INF, B_INF, S_INF
Reaction:
NONE
Acknowledge:
NONE
Cause:
Alarm threshold for I2t overload (p0294) of the power unit exceeded.
Remedy:
- reduce the continuous load.
- adapt the load duty cycle.
Reaction upon N:
NONE
Acknowl. upon N:
NONE
