SINAMICS S110 List Manual (LH7), 06/2012, 6SL3097-4AP10-0BP3
13: DI/DO 13 (X132.10)
14: DI/DO 14 (X132.12)
15: DI/DO 15 (X132.13)
To the terminal designation:
The first designation is valid for CU320, the second for CU305.
Remedy: - set the terminal as input (p0728).
- de-select the measuring probe (p0488, p0489, p0580).
Reaction upon F: OFF1
Acknowl. upon F: IMMEDIATELY
A07400 (N) Drive: DC link voltage maximum controller active
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: The DC link voltage controller has been activated because of the upper switch-in threshold (r1244).
A system deviation can occur between the setpoint and actual speed.
See also: r0056 (Status word, closed-loop control), p1240 (Vdc controller or Vdc monitoring configuration)
Remedy: Not necessary.
This alarm automatically disappears after the upper threshold has been distinctly undershot.
Otherwise, apply the following measures:
- use a Braking Module or regenerative feedback unit.
- increase the ramp-down times (p1121, p1135).
- shut down the Vdc_max controller (p1240 = 0).
Reaction upon N: NONE
Acknowl. upon N: NONE
A07402 (N) Drive: DC link voltage minimum controller active
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: The DC link voltage controller has been activated due to the lower switch-in threshold (r1248).
A system deviation can occur between the setpoint and actual speed.
A possible cause can be e.g. that the line supply has failed.
See also: r0056 (Status word, closed-loop control), p1240 (Vdc controller or Vdc monitoring configuration), p1248
(DC link voltage threshold lower)
Remedy: Not necessary.
This alarm automatically disappears after the lower threshold has been distinctly exceeded.
Otherwise, apply the following measures:
- check the line supply and infeed.
- increase the ramp-up times (p1120).
- shut down the Vdc_min controller (p1240 = 0).
Reaction upon N: NONE
Acknowl. upon N: NONE
F07403 (N, A) Drive: Lower DC link voltage threshold reached
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The DC link voltage monitoring is active (p1240 = 5, 6) and the lower DC link voltage threshold (p1248) was reached
in the "Operation" state.
Remedy: - check the line supply voltage.
- check the infeed.
- reduce the lower DC link threshold (p1248).
- switch out (disable) the DC link voltage monitoring (p1240 = 0).
