Remedy: Contact the manufacturer.
F30015 (N, A) Power unit: Phase failure motor cable
Message value: -
Message class: Application / technological function faulted (17)
Drive object: VECTOR_G
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: A phase failure in the motor feeder cable was detected.
The signal can also be output in the following cases:
- The motor is correctly connected, but the drive has stalled in U/f control. In this case, a current of 0 A is possibly
measured in one phase due to asymmetry of the currents.
- the motor is correctly connected, however the closed-speed control is instable and therefore an oscillating torque is
generated.
Note:
Chassis power units do not feature phase failure monitoring.
Remedy: - check the motor feeder cables.
- increase the ramp-up or ramp-down time (p1120) if the drive has stalled in U/f control.
- check the speed controller settings.
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
A30016 (N) Power unit: Load supply switched out
Message value: %1
Message class: Network fault (2)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: The DC link voltage is too low.
Alarm value (r2124, interpret decimal):
DC link voltage at the time of trip [0.1 V].
Remedy: - switch on load supply.
- check the line supply if necessary.
Reaction upon N: NONE
Acknowl. upon N: NONE
F30017 Power unit: Hardware current limit has responded too often
Message value: Fault cause: %1 bin
Message class: Power electronics faulted (5)
Drive object: B_INF, VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The hardware current limitation in the relevant phase (see A30031, A30032, A30033) has responded too often. The
number of times the limit has been exceeded depends on the design and type of power unit.
For infeed units, the following applies:
- closed-loop control is incorrectly parameterized.
- load on the infeed is too high.
