11.1
Unit information
11.1.1 Fault memory
The inverter stores the error message in fault memory P080. The inverter does not save
a new fault until the error message has been acknowledged. The local operating panel
shows the most recent fault. Whenever double faults occur, the value stored in P080
does not correspond to the value displayed on the operating panel. This is an example
of what happens with F-07 DC link overvoltage followed by F34 Ramp timeout.
The inverter stores the following information when a malfunction occurs:
•
Fault occurred
•
Status of the binary inputs / binary outputs
•
Operating status of the inverter
•
Inverter status
•
Heat sink temperature
•
Speed
•
Output current
•
Active current
•
Unit utilization
•
DC link voltage
11.1.2 Switch-off responses
There are 3 switch-off responses depending on the fault:
Immediate switch
off
This fault response causes immediate locking of the output stage with simultaneous
control of the brake output so that an existing brake is applied. The "fault message" is
set and the "ready message" is revoked.
This status can only be exited by an explicit fault reset.
Stop
This fault response causes a stop at the set stop ramp. This fault stop is subject to time
monitoring. If the drive does not reach the start / stop speed within a specified time
period, the unit jumps to the fault state, the output stage is inhibited and an existing
brake is applied. The fault message "F34 Ramp timeout" is generated. The original fault
message is overwritten. If the drive reaches the start/stop speed, the unit jumps to the
fault state, the brake is applied and the output stage is inhibited. The "fault message" is
set and the "ready message" is revoked.
This status can only be exited by an explicit fault reset.
