SINAMICS S List Manual (LH1), 07/2007
F07404
Drive: Upper DC link voltage threshold reached
Drive object:
SERVO
Reaction:
OFF2 (NONE, OFF1, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The DC link voltage monitoring is active (p1240 = 1, 3) and the upper DC link voltage threshold (p1244) was reached
in the "Operation" state.
Remedy:
- check the line supply voltage.
- check the infeed module or the Braking Module.
- increase the upper DC link voltage threshold (p1244).
- switch-out (disable) the DC link voltage monitoring (p1240 = 0).
F07404
Drive: Upper DC link voltage threshold reached
Drive object:
VECTOR
Reaction:
OFF2 (NONE, OFF1, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The DC link voltage monitoring is active (p1240 , p1280 = 4, 6) and the upper DC link voltage threshold (r1242,
r1282) was reached in the "Operation" state.
Remedy:
- check the line supply voltage.
- check the infeed module
- adapt the device supply voltage (p0210).
- disable the DC link voltage monitoring (p1240, p1280 = 0).
F07405 (N, A)
Drive: Kinetic buffering minimum speed not reached
Drive object:
VECTOR
Reaction:
OFF2 (IASC / DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge:
IMMEDIATELY
Cause:
During kinetic buffering the speed fell below minimum speed (p1257 or p1297 for vector drives with V/f control) and
the line supply did not return.
Remedy:
Check the speed threshold for the Vdc_min controller (kinetic buffering) (p1257, p1297).
See also: p1257 (Vdc_min controller speed threshold)
Reaction upon N:
NONE
Acknowl. upon N:
NONE
Reaction upon A:
NONE
Acknowl. upon A:
NONE
F07406 (N, A)
Drive: Kinetic buffering maximum time exceeded
Drive object:
VECTOR
Reaction:
OFF3 (IASC / DCBRAKE, NONE, OFF1, OFF2, STOP1, STOP2)
Acknowledge:
IMMEDIATELY
Cause:
The maximum buffer time (p1255 and p1295 for vector drives with V/f control) has been exceeded without the line
supply having returned.
Remedy:
Check the time threshold for Vdc-min controller (kinetic buffering) (p1255, p1295).
See also: p1255 (Vdc_min controller time threshold)
Reaction upon N:
NONE
Acknowl. upon N:
NONE
Reaction upon A:
NONE
Acknowl. upon A:
NONE
A07409
Drive: V/f control, current limiting controller active
Drive object:
VECTOR
Reaction:
NONE
Acknowledge:
NONE
Cause:
The current limiting controller of the V/f control was activated because the current limit was exceeded.
Remedy:
The alarm is automatically withdrawn when increasing the current limit (p0640), reducing the load or using a slower
up ramp for the setpoint (reference) speed.
