Remedy: Reduce the power when generating.
Note:
- once the internal braking resistor has thermally recovered, it is enabled for further use.
- for a DC link coupling, the generating power of all the coupled power units must be taken into consideration.
F30078 Power unit: defective fan or line reactor has overheated
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The temperature monitoring of the internal braking resistor or the line reactor has responded. In addition to the OFF2
response, the use of the internal braking resistor was inhibited.
Note:
- an overtemperature condition of the internal braking resistor can only be initiated as a result of a defective fan.
- an overtemperature condition of the line reactor can occur when a DC link coupling is used – and if the power when
motoring, which is fed into the DC link - is not evenly distributed across the rectifiers of the power units.
Remedy: - check the converter fan and replace if necessary.
- reduce the motoring power.
A30502 Power unit: DC link overvoltage
Reaction: NONE
Acknowledge: NONE
Cause: The power unit has detected overvoltage in the DC link on a pulse inhibit.
- device supply 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: STO initiated
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The "Safety Integrated" function integrated in the drive has identified a fault in monitoring channel 2, and has initiated STO.
- forced checking procedure (test stop) of the safety switch-off signal path of monitoring channel 2 unsuccessful.
- subsequent response to fault F30611 (defect in a monitoring channel).
Fault value (r0949, decimal interpretation):
0: Stop request from another monitoring channel.
1005: STO active, although no STO is selected and no stop response with STO is active.
1010: STO inactive, although STO is selected or a stop response with STO is active.
1011: internal error for STO deselected in monitoring channel 2.
9999: Subsequent response to fault F30611.
Remedy: - select Safe Torque Off and deselect again.
- carry out a POWER ON (switch-off/switch-on) for all components.
- replace drive.
For fault value = 9999:
- carry out diagnostics for fault F30611.
Note:
SI: Safety Integrated
STO: Safe Torque Off
