1146
List Manual, 09/2017, A5E33842890
Fault value (r0949, interpret bitwise binary):
Bit 0: Phase U.
Bit 1: Phase V.
Bit 2: Phase W.
Remedy:
- check the motor data - if required, carry out commissioning.
- check the motor circuit configuration (star-delta)
- U/f operation: Increase up ramp.
- U/f operation: Check assignment of rated currents of motor and power unit.
- check the power cable connections.
- check the power cables for short-circuit or ground fault.
- check the length of the power cables.
- replace power unit.
F30105
PU: Actual value sensing fault
Message class:
Power electronics faulted (5)
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
At least one incorrect actual value channel was detected on the Power Stack Adapter (PSA).
The incorrect actual value channels are displayed in the following diagnostic parameters.
Remedy:
Evaluate the diagnostic parameters.
If the actual value channel is incorrect, check the components and if required, replace.
A30502
Power unit: DC link overvoltage
Message class:
DC link overvoltage (4)
Reaction:
NONE
Acknowledge:
NONE
Cause:
The power unit has detected overvoltage in the DC link on a pulse inhibit.
- device connection voltage too high.
- line reactor incorrectly dimensioned.
Alarm value (r0949, interpret decimal):
DC link voltage [1 bit = 100 mV].
See also: r0070 (Actual DC link voltage)
Remedy:
- check the device supply voltage (p0210).
- check the dimensioning of the line reactor.
See also: p0210 (Drive unit line supply voltage)
F30600
SI P2: STOP A initiated
Message class:
Safety monitoring channel has identified an error (10)
Reaction:
OFF2
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
The drive-integrated "Safety Integrated" function on processor 2 has detected an error and initiated a STOP A.
- forced checking procedure (test stop) of the safety switch-off signal path on processor 2 unsuccessful.
- subsequent response to fault F30611 (defect in a monitoring channel).
Fault value (r0949, interpret decimal):
0: Stop request from processor 1.
1005:
- pulses suppressed although STO not selected and there is no internal STOP A present.
- For a Power Module with "STO via terminals at the Power Module" (STO_A/STO_B), these terminals are active
(DIP switch to "ON"). However, the "STO via terminals at the Power Module" function has not been enabled (p9601.7
= p9801.7 = 0).
1010: Pulses enabled although STO is selected or an internal STOP A is present.
1011: Internal fault for the pulse enable in the Power Module.
1030: Feedback signal of the safety switch-off signal paths for the "STO via terminals at the Power Module" function
different.
9999: Subsequent response to fault F30611.
