A07531
Drive: Command Data Set CDS not present
Reaction:
NONE
Acknowledge:
NONE
Cause:
The selected command data set is not available (p0836 > p0170). The command data set was not changed over.
See also: p0810, p0811, p0812, p0813, r0836
Remedy:
- select the existing command data set.
- set up additional command data sets.
F07800
Drive: No power unit present
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
The power unit parameters cannot be read or no parameters are stored in the power unit.
Note:
This fault also occurs if an incorrect topology was selected in the commissioning software and this parameterization is then
downloaded to the Control Unit.
See also: r0200 (Power unit code number actual)
Remedy:
- carry out a POWER ON (switch-off/switch-on) for all components.
- check the power unit and replace if necessary.
- check the Control Unit, and if required replace it.
- after correcting the topology, the parameters must be again downloaded using the commissioning software.
F07801
Drive: Motor overcurrent
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.
- 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 current of power unit.
- Switch to rotating motor without flying restart function (p1200).
Note:
Limit current = 2 x minimum (p0640, 4 x p0305 x p0306) >= 2 x p0305 x p0306
Remedy:
- check the current limits (p0640).
- vector control: Check the current controller (p1715, p1717).
- U/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 for the star-delta configuration and rating plate parameterization.
- check the power unit and motor combination.
- Choose "flying restart" function (p1200) if switched to rotating motor.
F07802
Drive: Infeed or power unit not ready
Reaction:
OFF2 (NONE)
Acknowledge:
IMMEDIATELY
Cause:
After an internal switch-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.
