Overview of Alarms
SINAMICS-Alarms
1111: Friction characteristic record, positive direction selected (p3845) and positive direction inhibited
(p1111).
1198: Friction characteristic record selected (p3845 > 0) and negative (p1110) and positive directions
(p1111) inhibited (r1198).
1300: The control mode (p1300) has not been set to closed-loop speed control.
1755: For encoderless closed-loop control (p1300 = 20), the lowest speed value to be approached
(p3820) is less than or equal to the changeover speed, open-loop controlled operation (p1755).
1910: Motor data identification activated.
1960: Speed controller optimization activated.
3820 ... 3829: Speed (p382x) cannot be approached.
3840: Friction characteristic incorrect.
3845: Friction characteristic record de-selected.
Remedy: Fulfill the conditions to record the friction characteristic.
Re fault value = 0046:
Establish missing enable signals.
Re fault value = 0840:
Select OFF1 (p0840) only after the friction characteristic record has been completed.
Re fault value = 1082, 1084, 1087:
Select the highest speed value to be approached (p3829) less than or equal to the maximum speed
(p1082, r1084, r1087).
Re-calculate the speed points along the friction characteristic (p0340 = 5).
Re fault value = 1110:
Select the friction characteristic record, positive direction (p3845).
Re fault value = 1111:
Select the friction characteristic record, negative direction (p3845).
Re fault value = 1198:
Enable the permitted direction (p1110, p1111, r1198).
Re fault value = 1300:
Set the control mode (p1300) on the closed-loop speed control (p1300 = 20, 21).
Re fault value = 1755:
For encoderless closed-loop speed control (p1300 = 20) select the lowest speed value to be
approached (p3820) greater than the changeover speed of open-loop controlled operation (p1755).
Re-calculate the speed points along the friction characteristic (p0340 = 5).
Re fault value = 1910:
Exit the motor data identification routine (p1910).
Re fault value = 1960:
Exist the speed controller optimization routine (p1960).
Re fault value 3820 ... 3829:
- check the load at speed p382x.
- check the speed signal (r0063) for oscillation at speed p382x. If required, check the speed controller
settings.
Re fault value = 3840:
Make the friction characteristic error-free (p3820 - p3829, p3830 - p3839, p3840).
Re fault value = 3845:
Activate the friction characteristic record (p3845).
207965 <location>Drive: Save required
Message -
value:
Drive object: SERVO
Reaction: NONE
Acknowledge: NONE
Cause: The angular commutation offset (p0431) was re-defined and has still not been saved.
In order to permanently accept the new value, it must be saved in a non-volatile fashion (p0971,
p0977).
See also: p0431 (Angular commutation offset), p1990 (Encoder adjustment, determine angular com-
mutation offset)
Remedy: None necessary.
This alarm automatically disappears after the data has been saved.
