Faults and alarms
List of faults and alarms
Note:
For long-stator motors (p3870.0 = 1), the following applies:
The encoder must have completed the unparking procedure (r3875.0 = 1) before a changeover can be made to
closed-loop control with encoder. The encoder is unparked using binector input p3876 = 0/1 signal and remains until
a 0 signal in this state.
F07434 Drive: It is not possible to change the direction of rotation with the pulses enabled
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A drive data set was selected - with the pulses enabled - which has a different parameterized direction of rotation
(p1821).
It is only possible to change the motor direction of rotation using p1821 when the pulses are inhibited.
Remedy: - change over the drive data set with the pulses inhibited.
- ensure that the changeover to a drive data set does not result in the motor direction of rotation being changed (i.e.
for these drive data sets, the same value must be in p1821).

F07439 Drive: Higher current controller dynamic performance not possible
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The function "Current controller dynamics higher" (p1810.11 = 1) is selected, however is not supported by the power
unit (r0192.27 = 0) or by the safety technology without encoder (9506 = 1).
Fault value (r0949, decimal interpretation):
1:
- firmware of the booksize power unit is not up-to-date.
- blocksize or S120 combi power unit was used.
2:
- a sine-cosine encoder with encoderless safety technology is used.
Remedy: In general:
- Deselect the function "Current controller dynamics higher" (p1810.11 = 0) and if required, set the current, speed
and position controller again or calculate (p0340 = 4).
For fault value = 1:
- If necessary, upgrade the firmware of the booksize power unit to a later version (version >= 4.4).
- Use a booksize power unit (version >= 4.4).
For fault value = 2:
- Re-parameterize encoderless safety technology (9506 = 1) to safety technology with an encoder (p9506 = 0).

A07440 EPOS: Jerk time is limited
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: The calculation of the jerk time Tr = max(p2572, p2573) / p2574 resulted in an excessively high value so that the jerk
time is internally limited to 1000 ms.
Note:
The alarm is also output if jerk limiting is not active.
Remedy: - increase the jerk limiting (p2574).
- reduce maximum acceleration or maximum deceleration (p2572, p2573).
